at high temperature conductivity increases for conductor what will happen for long transmission when temperature is high?
1 3553I 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
5 8744when we r using single phase load and we have power cable of 3.5core with .5 of neutral and neutral is suppose to the returen path of the phase how much current will flow in the neutral.reply.

1512why do we measure VIBRATION in -24vdc and why we adjust gap voltage -9vdc to 10-vdc? i am trying to get this information since 5 years, yet i haven't get reliable answer, i hope i can get from you.
1399What should be the voltage between Neutral and Ground in secondary side of the step down transformer (230 V to 110 V) with no load condition?
