What is the meaning of capacity of a 63 Amps TPN MCB? Is it
the per phase capacity or the totol capacity?
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

a solar energy installation utilizes a three phase bridge converter to feed energy into power system through a transformer of 400v/400v.the energy is collected in a bank of 400v battery and is connected to converter through a large filter choke of resistance 10ohms.1.the maximum current through the battrey will be.2.the kva rating of the input transformer is.
