Current Transformer

A current transformer is defined as "as an instrument transformer in which the secondary current is substantially proportional to the primary current (under normal conditions of operation) and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections." This highlights the accuracy requirement of the current transformer but also important is the isolating function, which means no matter what the system voltage the secondary circuit need be insulated only for a low voltage.

We specialize in offering quality L.V. Tape Wound & Cast Resin Transformers of multi range that is manufactured using quality components, which are procured from reliable vendors. These are acknowledged among clients for long functional life, high efficiency, hassle free performance and robust construction. These are widely used in various industries for measuring, protection & for special protections purpose (CLASS: PS) (restricted earth fault & differential protection systems)
