Amgis Toroidal Power Products, LLC Current Transformers

Current transformers (CTs) are used for measurement of electric currents and can be known as instrument transformers. When current in a circuit is too high to directly apply 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 also 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. AS Series Current Sensors AS Series Current Sensors are designed as a low cost method of controlling, monitoring or measuring AC currents. The sensors serve as feedback elements between the output and pulse control circuitry, providing accurate regulation of switch mode power supp
