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…
