for a 132/33kv transformer secondary is star and is
connected to NER. and from secondary a cable is running to
33kv swbd. since the cable is single core do i have to run
neutral cable also to 33kv swbd.???

Answer Posted / ramesh
there is no need of taking neutral point unless u need.Because mostly in 33kv Switch board you will feed 33/11Kv or 33/6.6Kv Transformers ,which will be mostly in (Dyn11 ior Dyn1) or to any other 33KV boards. Any how you are not going to take any motors load directly in 33kv.so it s not neccessary. but if you feed any star connection load in Primary you need to take neutral point.
