Voltage Output Current Transformers

Voltage Ac Output Current Transformers (CTs) offered in 600v class. These current transformers can have an output of 333 mv ac or 1 v ac, and are available in Window sizes from 1.13 inches to 8.25 inches.

Voltage Ac Output Current Transformers have cRUus approval, and ratios from 50 to 3000 Amps Primary are available, depending on model.

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.
