i need your help doctor
as per attached file
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 & 150kv & 120 kv so the question is why this high voltage is appearing on the line ? due to shunt reactor phase reversing or there is another thing
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
-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 the line with reactor because synchro check relay was blocked due to 150 kV which was appeared on the line. as per relay settings the OHT line voltage at dead case should not be more than 13kv
Please how can I solve this problem?
the problem is coming from the shunt reactor or another thing else .
Also no transitions anywhere along the circuit lengh
