The main advantage of the potential transformer is which can be calibrating the high voltages by using of the secondary winding connected to the small voltmeter
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
It's a PT (potential transformer) that's attached to the bus.
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
The potential transformer is used in the electricity supply industry to measure accurately the voltage being used. The current transformer is basically a step down transformer.
what are the advantages of using instrument tranformers
Both are same. This is an instrument transformer used for metering & protections.
CT=========current transformer PT=========potential transformer these are the instrumental transformers.
find a decepticon
No actually not, there are many differences in so many things (1)Size:- Potential transformer has very smaller size then Power Transformer. (2)Capacity:- Power transformer is designed to work on kilo amperes where potential transformer has almost negligible current during operation. (3)Utility:- Potential Transformer is used to convert very high voltage to very low voltage and output is connected to a voltmeter which is calibrated accordingly to measure high voltage,where Power Transformer is used in transmissions of power supply.
