A current transformer (CT) is used for measurement of alternating electric current. Current transformers, together with voltage (or potential) transformers (VT or PT), are known as instrument transformers. When current in a circuit is too high to apply directly to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments. A current transformer isolates the measuring instruments from what may be very high voltage in the monitored circuit. Current transformers are commonly used in metering and protective relays in the electrical power industry.

We are offering current transformers. The basic application of current transformers are: lowering the very high primary current passing through bus bars, cables, or wires to 5a or 1a, a measurable quantity by measuring instruments. isolating the measuring instrument and protective devices from mains. reproducing proportionate primary current on its secondary side, as required for extending the range of the instruments.
