What is current transformer,what is potential transformer

Question

Accepted Answer

Current transformer is used to measure high currents while potential transformer is used to measure high voltages.

Current transformer is a type of instrument transformer that steps down high currents to a lower, measurable value.
It is commonly used in power systems to measure and protect against overcurrents.
Potential transformer is also an instrument transformer that steps down high voltages to a lower, measurable value.
It is used to measure voltage levels in power systems and provide accurate voltage signals for metering and protection purposes.
Both transformers are essential in power systems for accurate measurement and protection.

Accepted Answer

In a current transformer, the secondary winding possesses large numbers of turns on the secondary side and is connected to the current winding of the instrument. In a potential transformer, the secondary winding has a small number of turns on the secondary side and is connected to the meter or instrument.
