## Overview

The Current Sensor by FEYV is a state-of-the-art non-contact leakage current sensor designed for industrial applications. Weighing just 132g and featuring advanced permalloy construction, it offers high accuracy and stability for a variety of measurements, including AC leakage current and power factor, without the need to disconnect the line under test.

## Description

Feature:1. The open close high accuracy current transformer is suitable for the detection of AC leakage current, high order harmonic current, phase, electric energy, power factor, etc.2. Using new CT technology, no need to disconnect the line under test, non contact measurement, accurate measurement, safe and fast.3. The iron is made ofpermalloy and double layer shielding technology is adopted, so the influence of the external magnetic field is very small.4. This product is easy to operate and easy to carry, ensuring high stability and reliability for year round uninterrupted measurement.5. It can be connected to phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high accuracy digital multimeters, etc.How to Use:1. The measured current is induced by the sensor to output a current l1, and the current 1 forms a voltage U on the external sampling load resistance RL, and the measured current can be calculated by detecting the current 1 or U. Among them: l=n.l1; U=l1.RL. n is the turns ratio of the coil (conversion ratio)2. Separately jam the live wire or the neutral wire to measure the current of the circuit. (Note stuck 1 wire)3. Clamp the live wire and the neutral wire together to measure the single‑phase leakage current. (Note stuck 2 wires)4. Clamp the
