Answer / yogesh

If the synchronoscope reads in anticlockwise direction
means the generator is running too slow. To close the
Breaker the incoming Generator frequency should be higher
than the existing Generator. Than only the incoming
Generator will take the load as soon as the Breaker gets
synchronised

Answer / k.prakashchandra

The power required to run at synch speed will be drawn from
the system.

E.B sending end to receiving end 33kv ug cable laid 8Km,receiving end to ss1,ss2,ss3,ss4 all are Approx 800 Mtr,can go for 33KV to 430V or 33kv to 11kv in receiving end and 11kv to 430 near ss ,which one is good for technically and economically.

I have connected 04nos. earthings to a transformer through 04nos. earthing pits seperately. 02nos. earthings are connected to T/F body, and 02nos. earthings are connected to T/F neutral.T/F capacity is 2000KVA, 11KV/415V. But after completing of 02 years successful operation ,we are facing following problems- 1. CT/PT occured blast one time 2. HT cable box occured blast two times 3. One body earthing strip and one neutral earthing strip of transformer are overlapping at some places. Whenever these two strips are pressed at overlapped points, they made spark. What is the reason of spark? Please explain the reason & rectification of above problems
