Dear FPelec
line trap and coupling voltage transformer also connected to the OHTL . can you tell me what is the relation between line trap or ccvt and shunt reactor
You can see the voltage for L1&L2 is more than phase L3 . and as per the diagram there is different correspondence between the shunt reactor and line phases on L1&L2 .
Another thing I can add it when we disconnect the shunt reactor the voltage disappeared and became 10kv
I caould not energize...
what is the relation between 2 phases reversed in shunt reactor and increasing of line voltage
by other meaning what is effect of revering shunt reactor phases on the transmission line
attached photo for line relay reading...
1-ATTACHED DIAGRAM IS SHOWING 2 LINE ARE GOING 2 STATION IN SAME TOWERS
2-SHUNT REACTOR L1 & L2 ARE REVERSED
3-TL1 IS LOADED
4-CBs of TL2 is off and shunt reactor is connected to the line and earthing switch not applied from both sides
we found the voltage on the line TL 2 is 150 kv &...
AS PER THE ATTACHE FILE AND BB PROTECTION SCHEME HIGH IMPEDANCE (MFAC) THE CT SWITCHING CIRCUIT GOT DELAY WHEN THE BUS SECTION BREAKER TRIPPED OR OPENED MANUALLY SO I REMOVE THE GREEN LINE TO DISABLE THE SWITCHING OF THE CT CIRCUIT(TEMPORARY) SO WHAT CAN I DO TO SOLVE THIS PROBLEM TO AVOID THE...
what is the different between capacitor banks Y grounded and another type is Y un grounded ?
also i want to knew the advantage & disadvantage for both type
