Flickermeter Simulator

Power line flickermeter according IEC 61000-4-15 Edition 2.0

All devices and equipment must pass the oldest EMC standard which is the flicker-test. This standard defines how an equipment is allowed to draw power from the network without generating voltage fluctuations which would disturb lightning.

In most modern devices flicker is controlled by software (e.g. switching on and off of a heater), also hardware can be affected, e.g. if performance specification and flicker standard can only be reached through optimization of the form of the switching transient.
