Product Description

GDZG-500 Series 120kV/2mA Smart DC Hipot Test Set


General Information

GDZG-500 series of DC high voltage tester is testing DC high voltage for zinc oxide lighting arrester, magnetic blowing arrester, power cables, generators, transformers, switches and other equipments, which is suitable for electric power branch, power department of factories, scientific research units, railway, chemical industry, power plants.

GDZG-500 series Intelligent DC high voltage generator, using AIPWM technology, the inaccurate linearity of PWM technology is adjusted, so that the accuracy of the instrument has been greatly improved. And adopt AI technology to set the overvoltage protection and overcurrent protection instead of the digital dial switch can only set the voltage value, can not set the current value and voltage drift problem, on the basis of maintaining the manual 0.75UDC1mA function button, increased AI automatic zinc oxide surge arrester measurement, cable section withstand voltage test, automatic withstand voltage test function, and can directly print the test report and save the test report, avoiding the error of the test report handwriting (stored data can only start from 002) , The manual mode is retained, and the printing function under any voltage and current is added, as well as the total time T1 and split-time T2 functions. The instrument adds perpetual calendar and time functions, and the experiment report has time and date.


Features
 

1. Use large LCD screen, the operation is more user-friendly, can display voltage and current in real time.
2. Fully automatic test function of zinc oxide arrester, with printing function; accuracy ≤1%, ripple coefficient: ≤0.5%. keep manual 0.75UDC / 1mA. Function.
3. With large voltage feedback, the output voltage stability is high and the ripple coefficient is ≤ 0.5%.
4. Segment withstand voltage: The segment voltage and the measurement time of each segment voltage can be set according to the user to complete the automatic boost (automatic cable test).
5. Single voltage: set a test voltage value, the instrument can automatically rise to this voltage (transformer automatic test).
6. Micro-ammeter wireless transmission function: it can realize the wireless transmission of high-voltage current data to make the measurement data more accurate and reliable; it can improve the personal safety of the operator. (Optional)
7. Voltage and current digital protection. It solves the problem that the digital dial switch can only set the voltage value, but cannot set the current value and voltage drift, and the error is ≤1%.
8. With perpetual calendar, time, storage, printing and other functions.
9. Earth protection alarm function: If there is no earth connection or poor earth connection, a "wiring fault" will appear and an alarm will be given.
