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
