If I need to purchase a step-down transformer (from three
phase 33kV 50Hz to 400/230V), what additional information do
I need from the main supply power line?
Answer / subra
Operating voltage primary = 33KV
operating voltage secondary= 400v/230v
capacity of the transformer=?
tap changer =Online or off line
transformer oil cooling sys ONAN or ONAF
vector group=?
Indoor or oudoor tranformer
these are the details to collected

what is 400kv doble circuit quadpole tower?
When testing an earthing connection, we use a 60 or 100 candle bulb with a phase connected direct from supply and the other wire to the new earthing provided.If the bulb glows then the earth is ok.Else earth connection is not Ok. So, why dont we can use all the home appliances taking a single wire from the phase and the return connection to Earth instead of return connection to neutral?
Why should not we run the IM in low voltage, if runs means what will happen?(for example instead of 400V we give 250V supply)
