Electrical Fast Transient

Electrical Fast Transient Testing Services in Canada

Electrical Fast Transient (EFT) are high frequency pulses that occurs because of the arcing on the power lines due connection or disconnection. This also occurs when relays, contactors, motors, or any other inductive load are turned off, then power distribution system experiences bursts of narrow high-frequency transients which can affect the performance of electronic equipment or might damage it.

IEC 61000-4-4 defines the test procedure to simulate these electrical fast transients and test the product to verify its susceptibility level. At INTL Inc. we have EFT generator that complies with IEC 61000-4-4 requirement which can perform EFT test with following parameters:
