transformer is a static electrical device which convert
voltage without change frequency.

Answer / kannu

Transformer is static electrical device,it change voltage
and current at different rate without change power and
frequency.i.e. what we gave power to primary side it same
will be there in secondary side and also frequency.

Answer / rama maddileti

Transformer is a static electrical device witch transfer
electrical energy from one circuit to another circuit
without changing frequency but change the voltage and
current. secondary turns of transformer is higher than
primary turns that transformer is called step up transformer.
secondary turns of transformer is lower than primary turns
that transformer is called step down transformer.

Answer / umoru shaibu

A transformer is a static electrical device
which step up or step down voltage
without a corresponding change in
frequency.

Answer / praveen k

on 22.03.2015 at 17:15hrs Y phase 66kV class Power Trf-2 Current transformer has flashed over and oil came out. The failed CT has been replaced on 24.03.2015 at 13:15hrs and the Trf has been charged in presence of RT Hassan after conducting the pre-commissioning tests. On the same day at 17:00hrs the commissioned CT has again flashed over and immediately the Trf  has been isolated from power supply. It is confirmed the secondary is not opened and checked the earth integrity and is found ok. Here what would be the reason for the CT failure?
