Switching the transient process (to cut off inductive load, relay contact bounce, etc) usually interferes with other electrical and electronic equipment in the same circuit. This type of interference is characterized by high amplitude, short rise time, high repetition rate and low energy. Pulse generators are used for evaluating the performance of electrical and electronic equipment power supply port, signal, control and grounding ports when subjected to electrical fast transient burst interference. The EFT S/ T series are the state-of-the-art EFT/ Burst testers with a built-in coupling/ decoupling network for single phase or three-phase mains supply line and a HV terminal to connect a capacitive coupling clamp. Its performance fully complies with IEC 61000-4-4 standard.
