Revenue Grade Current Transformers

General Details

Revenue Grade Current Transformers

Revenue Grade Current Transformers (CTs) approved for revenue metering by Industry Canada, offering superior performance and a robust design. These current transformers have CSA/UL approval, and are offered in the 600 V Class series.

Revenue Grade Current Transformers are designed for applications which require maximum accuracy and precision, and come in a variety of window sizes and current ratings.

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 current to small, standardized values that are easy to handle for measuring instruments and protective relays. The Instrument transformers isolate measurement or protection circuits from the high voltage of the primary system. These units provide a secondary current that is accurately proportional to the current flowing in its primary, presenting a negligible load to the primary circuit.

These units are the current sensing units of the power system and are used at generating stations, electrical substations, and in industrial and commercial electric power distribution.

Advantages of Current Transformers are that the units can measure high current easily, high electrical isolation, simple construction, and easy maintenance and installation.
