What is tap changer of Transformer , which side it is connected , primary & secondary current calculation of 66/11kv transformer, safety device in transformer ?

Question

Accepted Answer

A tap changer is a device used to adjust the turns ratio of a transformer, typically connected on the high voltage side. Primary and secondary current of a 66/11kV transformer can be calculated using the transformer turns ratio. Safety devices in a transformer include Buchholz relay, pressure relief valve, and oil temperature gauge.

Tap changer adjusts the turns ratio of a transformer to regulate the output voltage.
It is usually connected on the high voltage side of the transformer.
Primary current of a transformer can be calculated using the formula: Iprimary = Isecondary * (Vsecondary / Vprimary).
Secondary current of a transformer can be calculated using the formula: Isecondary = Iprimary * (Vprimary / Vsecondary).
Safety devices in a transformer include Buchholz relay, pressure relief valve, and oil temperature gauge.
