Current and potential transformer
WebApr 4, 2024 · Definition : – A current transformer ( CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. These transformers with low range ampere meters are used to measure the current in the high voltage circuits. WebVoltage transformers (may it be low voltage transformer or high voltage transformer) focuses on the power source, measurement, and operating a protective relay. The current transformer, on the other hand, focuses …
