Project Description
Product Features:
The instrument uses waveform detection and Fourier transformation to monitor the discharge current at all times. When the discharge current is monitored, it immediately records the high voltage at the moment and cuts off the high voltage power supply within 0.2s. The test result has high accuracy, which is convenient for automatic measurement.
Full touch LCD screen, super large graphic operation interface, every process is very clear and clear. Operators can use it without additional professional training.
The instrument is easy to operate, and the data measurement is automatically completed under the control of the microprocessor. No manual intervention is required.
All-in-one model with built-in high-voltage power supply, which is convenient for on-site testing and reduces on-site wiring.
LTDB-40A overvoltage protector tester is widely used to test the power frequency discharge voltage of various electrical equipment, especially for the power frequency discharge voltage test of zinc oxide overvoltage protectors with gaps (also known as lightning arresters). effect.It also belongs to overvoltage test.
The over-voltage protector tester uses a new type of special circuit to monitor the test voltage waveform, and at the same time collect the discharge pulse signal of the current loop, automatically judge the gap discharge, lock the voltage peak value at the moment of storage, and send out an audible alarm signal. In order to remind the tester, and quickly cut off the test power supply to protect the test product and test equipment from overcurrent damage.
High-voltage protection: short-circuit, breakdown or high-voltage current fluctuations of the test product can cut off the output at a high speed in a short-circuit mode.
Low voltage protection: wrong connection of 380V, power fluctuation or sudden power failure, start protection, will not cause overvoltage.
Misoperation prevention: real-time monitoring of voltage and current; clear terminal high/low voltage; slow voltage increase, rapid voltage decrease, and sound alarm.
Anti-seismic performance: The instrument adopts a unique anti-seismic design, which can withstand strong long-distance transportation vibration and bumps without being damaged.
High-voltage cable: high-voltage resistant insulated wire, but for accurate measurement, please use it in the air.
