This device is capable of testing a wide range of electrical equipment, including various types of vacuum circuit breakers, sulfur hexafluoride (SF₆) circuit breakers, oil-immersed high-voltage circuit breakers, load switches, GIS earthing knife switches, contactors, relays, and air circuit breakers. It can measure a comprehensive set of data and waveforms related to circuit breakers, such as operation time, synchronization performance, bounce time (and bounce counts), travel distance, operating speed, operating voltage, operating current, pick-up voltage, and mechanical operation parameters. With robust anti-interference capability, it can withstand 15KV induced voltage on site. Additionally, it comes as standard with a 12-channel metal contact time testing function.
