There is a polarity relationship between the primary and secondary sides of the power transformer coil. If there are several coils or power transformers combined, their polarity needs to be known in order to be used correctly. For a power transformer with two coils, if the electric potential induced within…

The vacuum circuit breaker adopts a vacuum arc extinguishing chamber, and the dynamic and static contacts in the vacuum arc extinguishing chamber adopt flat butt contact. In order to ensure good contact between the dynamic and static contacts, sufficient contact pressure must be ensured; During the closing process of the…

One of the main differences between CT and PT transformers is their functionality.On the one hand, current transformers can reduce high currents to a safer and easier to manage level for you to measure. It converts large primary currents into small 1A/5A currents, which can be measured on an ammeter.On…

Cable withstand voltage test is a method of detecting faults in the presence of cables. During the testing process, it is susceptible to various factors, leading to problems such as faults and short circuits. Below are several main methods for cable withstand voltage testing.1、 Super low frequency withstand voltage testThe…

Vacuum circuit breakers are indoor distribution devices in a 3~10kV, 50Hz three-phase AC system. Its main function is to control and protect current and voltage in medium and high voltage transmission lines. It can be used for the protection and control of electrical equipment in industrial and mining enterprises, power…

High voltage testing is a dangerous task that requires preventive measures to ensure safety during the testing process. Here are some common preventive measures:1. Choose a suitable testing locationThe testing location should be in an area that is relatively quiet, unobstructed, well ventilated, well lit, and able to isolate personnel…
