“Ring type” CT is constructed of an iron toroid, which forms the core of the transformer, and is wound with secondary turns. The doughnut fits over the primary conductor, which constitutes one primary turn.

Our Ring Type CT are manufactured to IEC, IEEE/ANSI, CAN or AS standards. Our wide range of measurement / metering indoor current transformers rated for primary currents 1A - 28,000A with 1A or 5A typical secondary current rating. Customer specific secondaries available on request.

Slot/ Window/ Ring Type CT: CTs having an opening in the center to accommodate a primary conductor through it is known as ‘ring-type’ (or ’slot/ window type’) CT. Wound Type CT: A CT having a primary winding of more than one full turn wound on the core is …

Oct 12, 2020 · Ring Type – In this type, the CT is installed over a bus bar or an insulated cable and only a low level of insulation is present on the secondary coil. To obtain non-standard ratios or for other special purposes, more than one turn of …

An effective design of a Ring Type C.T. may be produced first time using the following procedure, without any previous experience.

Newtek ring type cts features a unique design that allows it to be easily installed around a conductor, enabling non-intrusive current sensing. Its high-quality materials and precision winding ensure accurate current measurement.

A current transformer (CT) is used where the current is too high to measure directly, or the voltage in the primary circuit is too high, so the galvanic isolation between primary and secondary is important for safety or technical reasons.
