OVER VIEW
1.1.
PROTECTION OF DISTRIBUTION LINES
Distribution lines have their own equipment outdoors, the types of loads are various, and the
configurations of the networks are flexible and complicated. There are many kinds of fault causes
such as direct contact of trees or birds, natural phenomenon of lightning or heavy snow, and fault
spread-out due to customer’s facilities. Among these faults, most of faults are temporary and the
dominant fault type is ground-fault.
For rapid fault detection and fault section isolation, blackout area minimization, many protection
devices such as Recloser, Sectionalizer, and Line Fuse are adopted. Among these devices,
Automatic Circuit Recloser is the most important protection device, whose main functions are fault
current trip and auto-reclosing.
One distribution line has over 2 Reclosers of serial connections or Recloser – Sectionalizer - Line
Fuse of serial connections. This configuration is the concept of Primary Protection and Back-up
Protection. In other words, protection coordination is required in the way that a protection device
nearer to fault point operates first to eliminate the fault and other devices farther from fault point
are configured to operate later with time delays.
1.2.
FUNCTION OF AUTOMATIC CIRCUIT RECLOSER
When a fault occurs on the load side of Recloser installed location, Recloser detects fault current,
trips fault current at high speed, and does reclosing actions after the set time to re-activate the
faulted section. In case of temporary fault, the fault can be removed by itself according to highspeed trip and dead time before reclosing actions. But, in case of permanent fault, because fault
current is still detected after trip and reclosing actions of pre-set counts, Recloser is locked out
finally as opened.
Recloser has the time delay element in protection function of its controller and can be freely
configured for protection coordination with other protection devices.

2.5.2.2 IEC60870-5-101
IEC 60870-5-101 is primarily used with relatively slow transmission media on the asynchronous
V.24 interface. The standard promises baud rates of up to 9600 bit/s, with much higher baud rates
(<115200 bit/s) actually being used. X.24/X.27 interfaces with baud rates up to 64000 bit/s, also
part of the standard's description, could not establish themselves and are rarely used.
2.5.2.3 IEC60870-5-104
IEC 60870-5-104 (also known as IEC 870-5-104) is an international standard, released in 2000 by
the IEC (International Electrotechnical Commission). As can be seen from the standard's full
designation 'Network access for IEC 60870-5-101 using standard transport profiles', its application
layer is based on IEC 60870-5-101. IEC 60870-5-104 enables communication between control

WAVEFORM EVENT RECORDER
Fault & PQM waveforms recording function are used to store the measured instantaneous
current/voltage values of pre-fault and post-fault at 128 samples per cycle. Record length, trigger
source and trigger position of pre/post-fault in recorded data are adjustable. The record types are
128 samples * 20 cycles, 64 samples * 40 cycles, 32 samples * 80 cycles, 16 samples * 160 cycles.
According to the purpose, operators can set the fault recording trigger source and trigger
position of pre-fault/post-fault. Trigger position means the percentage position in recorded fault
data, and the pre-fault data are recorded before this point and rest of the data are recorded as the
post-fault after this point. The recorded fault waveforms are also uploaded to FTU PC S/W, and
current/voltage waveforms at fault and protection elements operation can be analyzed with fault
evaluation.
This waveform recording fuction follows the COMTRADE file format rule.

PROTECTION FUNCTIONS
5.1.
FAULT DETECTION
FTU detects the Phase & Earth Fault and trip the breaker.
The fastest operation time is within 45msec including auto-recloser operating time. There are 58
trip curves, which can be selected for fast and delayed operation respectively. The Curve can be
edited by using several parameters, i.e. time multiplier, time adder and minimum response time.
And high current trip element can be used for instantaneous trip. It is definite time
characteristics. During cold-load condition, pickup multiplied by cold-load multiplier. During the
cold-load condition, time-delayed curve is applied instead of fast curve. This function can be
enabled or disabled by cold-load multiplier.
Earth fault detection function can be enabled or disabled by ‘Ground Protection Enable’.

TC Curve
FTU-R200 has 54 types of built-in TC curves including ANSI, IEC Standard curves. And customer
can define additional 4 curves as his own curves by using PC Software. Basically, built-in curves
have inverse time characteristrics, but can be easily adjusted by three parameters such as multiplier,
time adder and minimum response time. In engineering step, the selection and adjustments of TC
curves shall be done for the protection coordination with other protection devices in the feeder.
The follwing parameters are related to change and editing of TC curve’s characteristics.

Minimum Response Time
Time Multiplier is multiplied to the operating time of basic curve (TDM=1.0), then Time Adder is
added to the resulting operating time of the curve adjusted by multiplier. Minimum Response Time
defines the fastest operating time of the curve.

changes its shape, that is, the curve becomes less steep in time axis and operation time becomes
longer by a multiplier at the same current value like ‘B’ in the figure. The operating time at 16
times pickup becomes 0.06 sec. Then Time Adder shall be applied. The operating time of the

Coordination function prevents unnecessary trip of source-side Recloser by instantaneous element
due to load-side fault. When this function is set to on and the fault is restored to normal state by
load-side Recloser during source-side Recloser’s time-delayed operation, source-side Recloser only
increments the reclosing counts without tripping. However, source-side Recloser performs tripping
at the last reclosing count. If the Reclosing function is disabled, Sequence Coordination function is

Cold Load Pickup
Cold Load Pickup is the phenomenon that takes place when a distribution circuit is re-energized
following an extended outage of that circuit. Cold load pickup is a composite of two conditions:
inrush and loss of load diversity. The magnitude of cold load pickup current is a combination of
non-diverse cyclic load current, continuously operating load current, transformer magnetizing
current, capacitor inrush current, etc. The combination can result in current levels that are
significantly higher than normal peak load levels. Cold load pickup current can be high enough to
cause instantaneous overcurrent and/or time overcurrent relays to operate.
Cold load pickup is primarily an overcurrent condition. If degraded voltage is also a concern,
then the application of voltage sensitive relays should also be considered.
Figure 5-6 Cold Load Pickup Current Shape
In Cold Load Pickup mode, without changing operational characteristics, pickup level is changed
by the times of Cold Load Multiplier (0~10) and the characteristics of time-delayed element
operate even if the setting is in the Instantaneous element. If the transient current goes down and
retrains below the pickup level within Cold Load Duration, then the normal sequence mode is
restored after Cold Load Restore Time. The Cold Load Restore Time is fixed value of 30msec. These
setting exist for both phase fault and earth fault separately, and the value ‘0’ of Cold Load
Multiplier means Cold Load Pickup Function disabled. Normaly Reclosing Sequence mode is
applied.

SENSITIVE EARTH FAULT (SEF) DETECTION
On the non-grounded network, it is hard to detect fault current because ground current of nongrounded network is much low. Therefore, FTU-R200 is designed to measure zero-sequence values
from either external core Balanced Current Transformer (or ZCT) or Residual Connection of 3 Phase
Current Transformers to detect earth fault in the non-grounded network. This function is generally
called SEF detection.
In case of earth fault in the non-grounded network, since very small fault current due to line
capacitance component flows into the fault point from both sides, SEF detection also considers the
fault direction even in the radial network. Maximum Torque Angle is for setting the phase
difference between zero-sequence voltage and zero-sequence current, and the protection zone is
between -90° and +90° on the basis of Maximum Torque Angle. And it can be used for alarm or
Trip.

DIRECTIONAL BLOCKING
Directional Blocking is a protection feature that restricts tripping on faults to a designated side
of the recloser. It prevents nuisance tripping if particular network conditions are causing ‘False’
earth faults. In radial systems Directional Blocking prevents nuisance tripping by blocking faults in
the reverse direction and only responding to faults in the foward direction.
Protect for faults in the forward and reverse direction. A forward fault may use a different timecurrent curve and setting to a reverse fault (i.e. these are individually selectable). Both the forward
protection and reverse protection are operating at the same time. This is an additional protection
feature.

INRUSH RESTRAINTS
Inrush Restraint works by raising the phase and earth currents for a short period of time to allow
the inrush current to subside.
Inrush current is an over-current higher than pickup current level, which is mainly caused by
transformer’s excitation current at closing action. To distinguish inrush current from load current,
2nd harmonics percentage is adopted as a criterion.
When, in the setting, ‘Fault Detection-Inrush Block’ is set to ‘Yes’ and ‘Fault Detection-Inrush
Detection-Function In Use’ is set to ‘ON’, inrush current over pickup level is considered as normal
load current and reclosing sequence is not processed.
This Function can be used to detect magnetizing inrush condition by comparing 2nd harmonic
component to fundamental frequency component of current.

SWITCH INSTALLATION
The FTU-R200 provides a function to set ‘Reference Phase’ and the ‘CT Direction’ according to
the switch installation position and the current flowing direction.
Figure 6-1 shows the general and ‘assumed-default’ case of switch installation, in which the
distribution lines with current A, B, C are connected to the phase A, B, C terminals of the switch,
and the current is flowing A/B/C to R/S/T of the switch. In this case, the ‘Referece Phase’ setting
value should ‘A’, which means that the phase of current flowing into the phase A terminal of the
switch is ‘A’, In addition, the ‘CT Direction’ setting value should be ‘Foward’, which means that
the current is flowing in the direction from the phase A/B/C terminals to the R/S/T terminals of the

SHORT-DURATION VOLTAGE VARIATION
There are three types of short-duration voltage variations, namely, instantaneous, momentary
and temporary, depending on its duration. Short-duration voltage variations are caused by fault
conditions, energization of large loads, which require high starting currents or loose connections in
power wiring. Depending on the fault location and the system conditions, the fault can generate
sags, swells or interruptions. The fault condition can be close to or remote from the point of
interest. During the actual fault condition, the effect of the voltage is of short-duration variation
until protective devices operate to clear the fault.
6.2.2.1 SAG
A sag (also known as dip) is a reduction to between 0.5 and 0.99 pu in RMS voltage or current
at the power frequency for a short period of time from 0.5 to 10 cycle. A 10% sag is considered an
event during which the RMS voltage decreased by 10% to 0.9 pu. Voltage sags are widely
recorgnized as among the most common and inportant aspects of power quality problems
affecting industrial and commercial customers. They are particularly troublesome. Since they occur
randomly and are difficult to predict.
Volatge sags are normally associated with system faults on the distribution system, sudden
increase in system loads, lightning strikes or starting of large load like induction motors. It is not
possible to eliminate faults on a system. One of the most common causes of faults occuring on
high-volatage transmission systems is a lightning strike. When there is a fault caused by a lightning
strike, the voltage can sag to 50% of the standard range and can last from four to seven cycles.
Most loads will be tripped off when encounter this type of voltage level. Possible effect of voltage

56 / 111
ISO 9001 certified
Recloser controller FTU- R200
sags would be system shutdown or reduce effciency and life span of electrical equipment,
particularly motors.
Equipment sensitivity to voltage sag occurs randomly and has become the most serious power
quality problem affecting many industries and commercial customers presently. An industrial
monitoring program determined an 87% voltage disturbances could be associate to voltage sags.
Most of the fault on the utility transmission and distribution system are single line-to-ground faults
(SLGF).

6.2.2.2 SWELL
A swell (also known as momentary overvoltage) is an increase in RMS voltage or current at the
power frequency to between 1.01 and 1.5 Pu for duration from 0.5 to 10 cycles. Swells are
commonly caused by system conditions, switching off a large load or energizing a large capacitor
bank. A swell can occur during a single line-to-ground fault (SLGF) with a temporary voltage rise
on the unfaulted phases. They are not as common as voltage sags and are characterized also by
both the magnitude and duration. During a fault condition, the severity of a voltage swell is very
much dependent on the system inpedance, location of the fault and grounding. The effect of this
type of disturbance would be hardware failure in the equipment due to overheating.

breakers responding to overload, lightning and faults. Interruptions are the result of equipment
failures, power system faults and control malfunctions. They are characterized by their duration as
the voltage magnitude is always less than 10% of the nominal. The duration of an interruption can

STATUS MONITORING & CONTROL
7.1
SWITCH CONTROL
Recloser controller FTU- R200
Recloser can be controlled from remote or local operator place. Operator place can be changed
only at local front panel. ‘REMOTE CONTROL’ push button is to select the operator place. Operator
place is toggled between local and remote by pushing button. LED is lit if remote position is
selected. FTU-R200 begins with remote position at power-up. Control is allowed only at the
position selected.
Local switch control requires two-step operation. It’s for security of operation. ‘SELECT’ button
should be pushed before ‘CLOSE’ or ‘OPEN’. SELECT LED is lit if SELECT operation is valid. SELECT
can be canceled by pushing SELECT button again or automatically after SBO timeout without
operation. CLOSE or OPEN operation is valid while this LED is lit. Pushing CLOSE or OPEN button
outputs switch control signal with fixed time pulse which is configurable. Switch status change
input which is auxiliary contacts of switch stops continuing to output pulse. There are some
interlock conditions to inhibit FTU from outputting pulse signal.
Gas low, Switch handle lock, same status of switch auxiliary contacts ‘a’, ‘b’ are those. Close or
open pulse width shall be set longer than switch operating time.
Remote switch control is possible by using SCADA protocol DNP3.0 or IEC60870-5-101,
IEC60870-5-104 FTU-R200 supports SBO (Select Before Operate) or Direct operate. If the operator
place is set to ‘Local’, remote control commands are refused. Pulse width of remote control
command shorter than setting will be overridden by local configuration
7.2
SWITCH STATUS MONITORING
FTU monitors switch open/close, gas and lock status through auxiliary contacts. FTU scans these
contacts input every 5 milliseconds. Switch open/close status is determined by double binary input,
normally open and closed contacts. Changes of all input status are saved as events with time tag in
history buffer. For each contact input, on-delay time can be applied. It’s adjustable within
10~500ms by 5ms step.

Recloser controller FTU- R200
BATTEY MONITORING
FTU monitors external Lead-acid battery through the control unit, which are mounted on inner
back-side of control box. Battery voltage is supervised continuously during external AC supply loss.
If over-discharge condition occurred, the control unit sends alarm signal to RTU and disconnect
battery in order to protect battery cell damage after 1-minute delay. The delay enables RTU to
send alarm state to remote station via communication. Also while AC supply is applied, battery test
control activates this function with connecting dummy battery load during test pulse, which is
configurable. The test control command can be ordered at local or remote.

MEASUREMENTS
8.1
BASIC ELECTRIC QUANTITIES
Recloser controller FTU- R200
FTU has 3-phase currents and 6 voltages input. DSP digitizes these signals and calculates various
electric quantities. These are basically based on fundamental frequency components. DSP use FFT
(Fast Fourier Transform) algorithm to get the components. Also DSP calculates true RMS of 3phase currents and voltages which include system frequency components and 2nd~31th harmonics.
Actually harmonic components over than 31th are attenuated by analog filters. Electric quantities
calculated are listed in the following.
Currents (Ia, Ib, Ic, In)
RMS, Phase Angle, True RMS
Voltage (Va, Vb, Vc, Vr, Vs, Vt)
RMS, Phase Angle, True RMS
Apparent Power
A-Phase, B-Phase, C-Phase, 3-Phase Total,
Active Power
A-Phase, B-Phase, C-Phase, 3-Phase Total,
Reactive Power
A-Phase, B-Phase, C-Phase, 3-Phase Total,
Power Factor
A-Phase, B-Phase, C-Phase, 3-Phase Total,
Va-Vr Phase Angle Difference
Current, Voltage Unbalance
Frequency, Temporature
In the above items listed, active power, reactive power values are signed integer. Sign represents
power flow or if loads are inductive or capacitive. Also power factor has lead/lag state value
separately.
Currents and voltages have phase angles, which are relative phase angles compared to the
reference Va. These angles are useful to monitor the phase sequence and imbalance of distribution
line.
8.2
SEQUENCE COMPONENTS
FTU provides the sequence components of 3-phase currents and voltages. They are positive
sequence current (I1) and voltage (V1), negative sequence current (I2) and voltage (V2), and zero
sequence voltage (V0) which are calculated by 3-phase phasor quantities. This information can be
used to monitor imbalance of distribution line.

64 / 111
ISO 9001 certified
8.3
Recloser controller FTU- R200
HARMONICS
FTU extracts harmonic components from 3-phase current and voltage signals by using FFT (Fast
Fourier Transform). It provides 2nd to 31st harmonic magnitudes and THDs (Total Harmonic
Distortion) for each phase. THD is the total harmonic percentage to the fundamental frequency
component. FTU also calculates and provides 3-phase THD. These values may be used to monitor
the power quality of distribution line.
8.4
ENERGY
FTU provides active energy, reactive energy for each phase or 3-phase total. Also import, export
energy are accumulated on separate register. Units of energy are kWh, kVarh, which represent
primary distribution line energy flow. The values are represented by 16-bit rollovers kWh, kVarh
counters which are available at remote or local. Power calculation for energy is based on the
fundamental frequency component. It’s not for billing purpose, but for load management. Proper
energy accumulation needs that SCADA read energy counter with reset from FTU and accumulate
it on SCADA’s local register by periods shorter than the expected rollover time of the counter.

DEMAND CURRENTS AND POWER
FTU calculates and stores average of currents and active, reactive powers during the demand
interval, which is configurable as 5, 10, or 15 minutes. The buffer has 1023 demands. Also FTU
stores daily peak demand up to 1023.

The I/O mapping is created using the tool and saved to an IO File (*.iom). Once a valid file has
been created, it is linked to the Recloser device.
The IOConfig tool is intended to be used off-line only. Mappings are created, saved and linked
to FTUMan while disconnected from the FTU. Once these tasks have been completed the user
connects to the device and writes the new mapping into the Recloser.

Warning: Make sure the IOConfig Tool is closed after a mapping has been edited. If the
Tool is left open while the Automatic Data Retriaval feature is running it may attempt to
update a mapping file that is already open in the Tool. This will either cause the read

DNP3.0 Classes
There are four classes in DNP3.0. These are defined as follows:
0
Class 0 is not an event class. It is used when reporting current (static) data values and
not changes of state events.
Note: Setting a point to Class 0 will prevent the controller’s protocol handler from
reporting change of state events for that point to the master station. The point still
remains accessible through static data polls.
1
Class 1 used to report high priority events. Events in this class take precedence.
2
Class 2 used to report medium priority events.
3
Class 3 used to report low priority events.
