      1. Product Overview

      The zero-sequence current transformer cooperates with the relay protection device or signal when the power system generates the zero-sequence ground current, so that the device components operate to achieve protection or monitoring.

      2.product features

      1) A variety of aperture options to meet field cable requirements

      2) Choice of multiple capacities, ratios and exact limit factors

      3) It can be used with microcomputer protection, small current grounding line selection, relay, etc.

      4) Adopt ABS engineering plastic shell, resin is poured into full seal, good insulation performance and beautiful appearance

      5) High sensitivity, good linearity, reliable operation and easy installation

      6) The performance is better than the general zero-sequence current transformer, which has a wide range of use, not only adapts to electromagnetic relay protection, but also adapts to electronic and microcomputer protection devices.

      7) The user can select the appropriate zero-sequence current transformer according to the different operation modes of the system.
