Product Details

Overview

This tester uses the neutral point capacitance method to measure the capacitance current of distribution networks. It features a large-screen LCD display and Chinese menu. After safety measures are taken and parameters are set in advance, there is no need to touch the instrument during operation, making the work safe, simple, and fast. The test results are accurate, stable, and reliable, unaffected by other operating conditions, especially when the system is unbalanced.

Product Features

The current tester is a portable rectifier instrument with high sensitivity and multi-range protection circuits. Its characteristics are: wide measurement range, with a total of twenty ranges, capable of measuring AC/DC stray voltage and stray current separately. It does not require its own power supply and is safe and reliable. It is suitable for testing currents and voltages generated by steel rails, water pipes, cables, etc. in coal mines, preventing premature explosion of pipes and other combustion accidents caused by stray current discharge, minimizing fire sources in mines.
