Timer Logic: If the measured value of the impedance falls in zone-2, zone-3, zone-4 or zone-5, the relay starts a timer.

When the timer count value exceeds the preset value for the corresponding zone, the flag for the fault

detection of that particular zone is set. Timers are incorporated in the software by counting the number of

samples during processing. If the fault in zone-1, the trip signal is issued by the relay only after ensuring

the impedance consistency for the subsequent three samples.

For Three Phase Fault In case of a three phase fault, positive sequence current should be greater than the set value.

During power swing condition, the relay operation should be blocked. Power swing is sensed when the

computed value of the impedance is found to lie within the power swing band for more than the preset

value of the timer to detect power swing blocking condition. If the measured impedance lies in the power

swing band for more than the fixed time of 35ms, the relay operation is blocked for a period of selectable

time otherwise the distance relay operates in the normal ways.

Load Encroachment Detection: If the transmission line is long and the resistive setting chosen conflicts with load, a load encroachment

element is required. The purpose of this element is to avoid trip in high load conditions. They blocked the

operation of distance elements if the calculated positive sequence impedance stays within the range set

for the timers.

Trip logic : Two independent positive-sequence impedance ie. Complex positive sequence impedance

characteristics monitor load conditions and test it against the boundaries of these regions. If the

impedance is inside either region, or the load-encroachment logic is enabled (ELE = Y), then the relay

concludes the impedance represents load, and three-phase distance elements are blocked.

If the impedance is outside both load regions, the Quadrilateral elements are permitted to operate.

immediately following manual closure of the circuit breaker. SOTF protection remains enabled for 500ms

following circuit breaker closure, detected via the CB Man Close input or CB close with CB control or for

the duration of the close pulse on internal detection.

(E) Trip circuit Supervision:-

The ADR239A is having 2 separate digital opto-coupler status input which can be used to

continuously monitor continuity of trip-circuit. The general scheme is shown in below fig.

Relay monitor Trip coil continuity through CB NO during close condition and through CBNC

during Trip condition. If any discontinuity observed it generate Alarm signal.

The output marked as PROTH (Protection healthy) is normally is ON and become OFF at

following condition

When DC supply is not sufficient (DC fail)

When T1 and T2 both active and both inactive.

i.e CB NO as will as CB NC are both close or open. Relay detects any internal hardware

Error.

Breaker Failure Detection:- The breaker failure function is used to quickly detect that a circuit-breaker has not opened (phase fault

currents still present) after a trip signal. This function is based on a "I<BF" current threshold setting 10% to

100% and on a "tBF" time-delay; these two settings can be configured by the user in General Settings

Menu. Normally after tripping, current should become Zero within 100 – 200ms time depending upon type

of fault and breaker mechanism. After Fault ADR239A trigger internal timer (settable from 100 ms to 1000

ms) if fault is not cleared during this time then relay declare as Breaker fail (LBB function) and change

another contacts. This contact is marked as Breaker Fail can be used to trip back up breaker or can be

used to generate ALARM signal.

I/O and Programmable AND Logic Eque. AND LOGIC EQUAT allows the operator to program four AND logic equations. Each equation can be the

logic AND link of signals from internal functions or from external binary input signals. In this submenu, the

operator sets the parameter cells of each of the 4 AND logic equations by assigning individual signals to

the individual AND logic equations. An operating timer stage and a reset timer stage are assigned to each

AND logic equation. These eight independent timer stages can be set in the submenu AND LOGIC

EQUAT T DELAY.

The operating timer stage Toperate is initiated only if all the associated data in the logic equation are in

logic state 1 (AND gate). It allows the logic equation validation to be delayed for a time period set in

Toperate. The reset timer stage Treset is initiated as soon as any of the data associated with the equation

disappears i.e. goes to logic state 0. It allows the logic equation to remain valid for a time period set in

Treset.

Programmable DI/DO and LED:- The ADR239A has 10 digital outputs, 2 status dedicated for CBNO (T2) & CBNC (T1) and 8 status

programmable opto-isolated input and 8 nos.of dual LEDs out of which 6 are programmable. These can

be programmed by local key board or through communication protocol. Any logical or physical status can

be assigned to any relay contact or any programmable LEDs. Many additional functions such as Ext

Reset, Thermal Reset, The disturbance record trigger, Trip, Blocking different protection etc. can be

configured to any of 8 Physical Status Inputs.

Monitoring Functions (Event, Disturbance Record):- Apart from basic protection functions relay is continuously monitors all numerical three phase distance

operation through status, its internal functions, internal hardware etc. If any change is observed, it is

marked as event. Such types of events are stored in internal non-volatile memory along with time stamp.

Following are some of the events. Relay PKP, Relay Reset, CB Trip, CB close, changed of any digital

status input, Change in Relay settings etc.

Up to 100 such events can be stored and can be downloaded for detail analysis. Apart from Event record,

relay also records actual waveform of current and voltage along with all digital and logical status during

fault condition. Up to 10 such waveforms can be recorded; the duration of disturbance record is 1 sec.

The disturbance record can be trigger from physical status input as well as from pick-up, trip operation of

relay. This waveform can be downloaded through communication port for further analysis.
