Our Products
Our offered Product range includes Current Transformers and DC Immune CTs for Thread through Meters.
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.
Energy meter CTs made using hybrid cores are DC immune current transformers for energy meters meeting IS 13779 / IEC 62053. The CT is small in size with customized casing and metal shield, (optional) for protection against external magnetic field. The wound CT is epoxy potted for durable and long life performance. Number of turns can be wound/adjusted as per customer requirements. CTs can be provided with or without metal shield in custom casings.
