Switch Dynamic Characteristics Test Set

• The RDGC-8C high voltage Switch Dynamic Characteristics Test Set, also known as the high voltage switch mechanical characteristics tester, is designed based on the latest national standard "High Voltage AC Circuit Breaker" GB1984-2014. It also refers to the power industry standard of the People's Republic of China, "General Technical Conditions for High Voltage Test Equipment" Part 3, DL/T846.3-2017, as the design foundation. This tester provides convenience for the dynamic analysis of various types of circuit breakers and can accurately measure the mechanical dynamic characteristics of high voltage circuit breakers of various voltage levels, such as less oil, more oil, vacuum, and SF6.

• In the power system, the high voltage Switch Dynamic Characteristics Test Set circuit breaker is responsible for both control and protection tasks, and its performance is directly related to the safe operation of the power system. Among the various parameters used to evaluate the performance of circuit breakers, the mechanical characteristic parameter is one of the most important.
