YLGDY-30Overvoltage protector comprehensive testerIt is a testing instrument developed by Shaanxi Yilian Electric specifically for the power frequency discharge voltage test of zinc oxide overvoltage protectors (also known as lightning arresters or TBPs) with gaps. It adopts a new type of special circuit to monitor the waveform of the test voltage, collect the discharge pulse signal of the current circuit, automatically judge the gap discharge, latch the voltage peak value at the moment of discharge, and emit an audible alarm signal to prompt the tester and quickly cut off the test power supply, protecting the test sample and test equipment from overcurrent damage.

YLGDY-30Overvoltage protector comprehensive testerIntegrating power supply, measurement, and control system, it is small in size, light in weight, easy to carry, easy to operate, safe and reliable, and widely used in various electrical equipment power frequency discharge voltage tests.
▍ Functional Features ↴
◆ The instrument uses waveform detection and Fourier transform to constantly monitor the discharge current. When the discharge current is detected, the high voltage is immediately recorded and the high voltage power supply is cut off within 0.2 seconds. The test results have high accuracy, making it easy to achieve automated measurement.
◆ Full touch LCD display screen, super comprehensive graphical operation interface, clear and concise operation process, and operators can use it without additional professional training.
◆ The instrument is easy to operate, and data measurement is automatically completed under microprocessor control without manual intervention
◆ Integrated model with built-in high-voltage power supply for easy on-site testing and reducing on-site wiring.
◆ High voltage protection: The test sample can cut off the output at high speed by short circuit, breakdown or high voltage current fluctuation.
◆ Low voltage protection: In case of accidental connection to 380V, power fluctuation or sudden power outage, the protection will be activated without causing overvoltage.
◆ Anti misoperation: Real time monitoring of voltage and current, clear distinction of high/low voltage at wiring terminals, slow rise and rapid drop of voltage, sound alarm.
◆ Seismic performance: The instrument adopts a unique seismic design, which can withstand strong long-distance transportation vibrations and bumps without damage.
◆ High voltage cable: It is a high-voltage insulated wire, but for accurate measurement, please use it suspended.
