Calculate : 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 = 240 o ( in Reverse Side )

Calculate : R= Z x COS Φ , X= Z x SIN Φ

Then measure the impedance ( Z ) ( Primary & Secondary )

Note :

[ C.T ratio = 1200 / 1 ] & [ V.T ratio = 110 / 0.1 K.V ]

= 1200 = 1100

** When the Fault comes to the line , the Voltage will decrease Or the Current increase , then the Impedance will decrease in very short time , then the relay will trip according to the setting of the fault case.

** In the Power Swing case , the Impedance will decrease but in very short time , it will be decrease related with proper time for that decreasing, so the Power Swing depend on changing the Impedance with Time ( dZ / dt ). However , the time has to be proper with this changing ( Not very short when the Impedance will decrease ) , then the relay will Block all the Zones ( in case of chosen “All zones Blocked “ in Address No:2002 )

Test Procedure with OMCRON Using ( State Sequencer ):

1 - Inject Normal Current & Normal Voltage. 2 – Then Decrease the Voltage by constant ( d / dt ),

[ (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 5Ω5 –When the Impedance enter the Polygon ,the Timer in Address No: 2007 : :Trip Delay after Power Swing Blocking 5 Sec. , Will Operate . ( 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.

Instead of using Binary Input : CB. Manual Close , we can Inject Current Less Than the Current in Address No: 1130 for a period of time =250 mSec ,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.
