Introduction
High Voltage Primary Current Injection Test Unit is an electrical test instrument used to verify the condition and performance of high-current circuit breakers, protective relays, and other electrical equipment that operate at high current levels.
Features
1>Output voltage: generally in 4-10V, require special output by the user2>Output current: 50-30000A3>Working time: short time workingAt rated output: 2.5 minutes when working1/2 rated output: 30 minutes when working1/3 at rated output: 40 minutes at work1/4 at rated output: long-term use;4>The capacity of the equipment is designed according to the 5-minute short-time working system, such as for intermittent work, the power-on time is less than 2.5 minutes, and the working cycle should be greater than 10 minutes.
