The zc-320 leakage protector tester developed by our company is mainly used to test the leakage action current, leakage non action current and leakage action time of the leakage protector. The test current is 0-500ma, which is divided into ten levels, the time test range is 0-799ms, and the 16…

At present, the FSK power carrier principle is used to measure the station area. Due to the defects in the principle, there are various problems in the actual use process, such as crosstalk, short transmission distance, large load impact, common cable interference and so on.   Based on this problem,…

I believe that when we use the wireless secondary load and voltage drop tester, we must also have encountered many problems, resulting in slow work efficiency and repetitive work. Therefore, this paper specifically answers the common problems and solutions of wireless secondary load and voltage drop tester.   Before answering…

Electric power workers often need to use dry-type test transformer in practical work, so what is the correct use method of dry-type test transformer? This paper takes zc-501c series dry test transformer newly developed by Zhuo measurement and control as an example to introduce the correct use of dry test…

Insulating oil micro water measuring instrument is a powerful instrument which can be used to measure micro water content of different substances by Karl Fischer coulometry. It uses the advanced automatic control circuit, 32-bit embedded microprocessor as the main control core, embedded in the mini operating system, so that the…

Induction voltage regulator is a kind of voltage regulating equipment. It uses the principle of electromagnetic induction to feed the primary electric energy to the secondary through magnetic field induction. It can also change the relative angular displacement of the axis of stator and rotor winding and a certain connection…

The gas relay calibrator is mainly used in the power system to check the operation velocity of heavy gas protection, the operation volume of light gas protection and the sealing test of gas relay. In addition, it can also test the opening and closing pressure of the pressure relief valve,…
