DC breaker breaker tester Ann second characteristic tester DC circuit breaker safety second characteristic tester I. Product Overview To prevent the DC circuit breakers and other electrical operating characteristics of DC protection does not match the potential threat, the State Grid Corporation for new clothes and operation of the DC protection appliances, provides security second characteristic test must be carried out. For this reason I introduced a suitable RTAS-1000A DC circuit breaker substation site in seconds using a safety tester, you can direct protection of electrical operating characteristics and should be verified with the differential to improve the reliability of the DC system operation, ensure the safety of the power grid reliable operation. Second, the main technical requirements), the product features: the main section using high-performance industrial computer, windows operating system, real-time display waveforms and numerical parameters; linear constant current control technology, new power devices, constant???? stream of high precision, test current set their own; test method:?? whole point test or snapshot test; can switch over current and short circuit current speed off test; equipment with self-protection, and ensure the safety of the testing process???? and reliability;?? management software for secure second characteristic curve of the circuit breaker, data, query, analyze and report output functions.
