We liven our new UG transmission cable last nite 33kV. This is a backup transmission line to the parallel OH line.
OverHead (OH) trans already on service.
Underground (UG) energise last nite and causing Generator MVARs to drop down.
Soon after we liven this UG cable the Generator MVAR drops down to 500kVAR (Machine Rating 5770kW @ 0.8pf, 11kV).
On the UG cable relay info
Apms per phase: 20A
MWatts: 0
MVARs: -1.2MVARS.
Need to know if this UG cable inject pure capacitive load to the system.
The generators running on low MVARs with High KV.
Thanks
