dilo current transformer high-voltage unit

dilo current transformer high-voltage unit

Transformers contain input, known as the "primary," and output, known as the "secondary," terminals. The transformer's label identifies the input (high voltage) and the output (low voltage) sides, along with the input and output voltages -- measured as voltage-alternating-current (VAC) -- and their corresponding terminals.

  • Current transformer - Wikipedia

    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. Current transformers, along with voltage or potential transformers, are instrument transformers.Instrument transformers scale the large values of voltage or current to small, standardized
