TRAK-B Series Split-core Outdoor Waterproof Zero-sequence Current Transformer

Product Overview

A 0–10mA Core Balance Current Transformer CBCT ( Zero Sequence Current Transformer ZCT) is a precision sensing device designed to detect leakage or residual currents in electrical power systems. It operates by measuring the vector sum of the currents flowing through three-phase conductors. Under normal balanced load conditions, the sum of all phase currents equals zero, and no output signal is generated. When a ground fault, insulation failure, or leakage occurs, an imbalance arises, and the transformer produces a corresponding secondary output signal, typically within the 0 ~ 10mA range, proportional to the fault current.

Product Features

*  Split-core structure, easy to install on site and easy to operate.

*  The magnetic core winding structure is cast with epoxy resin, and the end faces of the incision are matched, and the stability is good.

*  Adopt high-permeability ultra-microcrystalline core, with good linearity and high sensitivity.

Product Application

Electrical fire monitoring system, fire-fighting equipment power monitoring system, rural power grid reconstruction project, intelligent power consumption system, low-current grounding system, electromagnetic relay protection, online environmental monitoring, etc.

Installation Precautions

*  The live wire and the neutral wire must pass through the core hole of the transformer at the same time.

*  Before the iron core is closed, ensure that the end face of the incision is clean, free of stains and impurities

*  Use a torque wrench (electric/pneumatic) when tightening the screws, and set the torque to a reasonable range.
