Can isolate the secondary from primary

Better voltage regulation

Used for power distribution

Can be used in EHT supply

Servo line correctors

For low voltage distribution

To measure the voltage

To measure the current

To reduce the voltage drop

To increase the output voltage

To reduce the no of transformer

Provides more reliability of power

Phase sequence must be same

Type must be same

Polarity must be same

Capacity must be same

Transform 3 phase to 2 phase

To stabilize the output voltage

To get rated power output

Transform 3 phase to 6 phase
