Note : Before starting this test , for easy calculation & to get correct readings In the relay configuration , Setting Group A , power system data 2 Address (1116-1119) : setting for Zero Sequence Compensation Factors RE / RL =0 & XE / XL = 0 ,
Also Zero Sequence Compensation Factors in the Tester setting should be Zero
► ( I ) Inject the impedance ( Z ) = 6 Ω Calculate :
with angle Φ = 60 o ( in Forward Side )
R= Z x COS Φ
,
X= Z x SIN Φ
Then measure the impedance ( Z )
( Primary & Secondary )
► ( II ) Inject the impedance ( Z ) = 6 Ω with angle Φ = 240 o ( in Reverse Side ) Calculate :
R= Z x COS Φ
Then measure the impedance
, ( Z )
X= Z x SIN Φ
( Primary & Secondary )

Using ( State Sequencer ):
. Inject Normal Current & Normal Voltage - 1 ,( Then Decrease the Voltage by constant ( d / dt – 2 [ (i.e.) Decrease the Impedance by ( dZ / dt ).] 3 -The Power Swing depend on changing the Impedance with Time( dZ/dt ) 4 -The Power Swing Impedance starts before Z5 by 5Ω 5 –When the Impedance enter the Polygon ,the Timer in Address No: 2007 : :Trip Delay after Power Swing Blocking

( i ) If the changing of the Impedance in the Polygon is slowly ,
then the relay will be Blocked by The Power Swing Function. ( ii ) If the changing of the Impedance in the Polygon is fastly and the Impedance is go out from the Polygon , then any Fault will make Trip.

So , the relay will know that the CB. of the Feeder as it is Opened ( OFF ), also the Time in Address No: 1132A , helping in Monitoring the Increase in Current after CB. is Closed ( ON ), If During that time 250 mSec , the Current Increased More than the Current in Address No: 1130 , Then the relay will be Tripe By SOTF Function. Hence , we can make this Test as following : 1134 : Recognition of Line Closures with(Current flow OR Manual Close Bi)
