Effects of Electric Current on Human Body

When an electrical current traverses the human body, the nervous system endures an electric shock. The severity of this shock predominantly hinges on three key factors: the magnitude of the current, the pathway the current follows through the body, and the duration of contact. In the most severe ins

What is Automatic Voltage Regulator?

An automatic voltage regulator is employed to regulate voltage, converting fluctuating voltages into a constant one. Voltage fluctuations mainly stem from variations in the load on the supply system. Such voltage variations can damage the equipment within the power system. These fluctuations can be

Research on the Application Mode and Operation Monitoring of Tank-type Circuit Breaker Heating Tapes in 500kV Substations in High-Cold Areas

At present, most low - voltage switchgear assemblies in China mainly use SF₆ gas at a pressure of 0.5 - 0.6 MPa as the insulating medium. However, when the ambient temperature drops to around - 32.5 deg;C, the SF₆ gas will quickly liquefy, resulting in serious problems with the insulation and interr
