EMC analysis of discontinuous disturbances (click rate)
Most modern electronically controlled appliances still switch their loads – such as heating elements and motors – with mechanical relays. Each relay opening or closing generates a short, broadband click that can exceed the disturbance voltage limits of a quasi-peak (QP) detector. Because these transients are intermittent, they are evaluated separately as discontinuous disturbances (clicks) in line with CISPR 14-1/EN 55014-1.
