Product Overview

The through-type racetrack-shaped window current transformer (also known as high-precision current transformer) is suitable for energy metering, high-accuracy limiting protection and current measurement in AC power systems of 10kV~35kV. Designed for metering of incoming cables and high limiting protection of outgoing cables in ring main units and switching stations, this type of current transformer can pass two or multiple cables, perfectly solving multi-circuit outgoing line problems. It can replace high-voltage busbar-type metering transformers (LZZB series). With small size, high metering accuracy (Class 0.2S), it is a full-working-condition product that can operate in various environments and is maintenance-free. It reduces equipment footprint, lowers costs and improves reliability. It is applied in fully insulated, fully sealed compact switchgear such as Safeplus, SM6, 8DH, FB, GA/GE, SS and FIT series.
