|What is the meaning of BUS?
|What is HT? And specify the range of voltage?
|if the transformer at full load have a iron loss =900w and copper loss = 1600w . what percent of the load will the transformer has a maximum efficiency?
|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
