What is Inside an Current Transformer in Tamil l CT Dismantling l CT Construction and Working

‪@Engineering-in-tamil‬ #Current Transformer Current Transformer  is a device used to produce an alternating current in its secondary, which is proportional to the AC current in its primary. This is primarily used when a current is too high to measure directly. The induced secondary current is then suitable for measuring instruments, which typically needs isolation between the primary and secondary circuit. An electrical CT differs from a voltage or power transformer because it consists of only one or very few turns as its primary winding. the primary current is not dependent on the secondary load current but instead is controlled by an external load. The CT ratio is equal to the number of secondary turns. This ratio is based on the primary conductor passing once through the transformer window.
