The variation in current supplied to appliances connected to the electricity supply causes local voltage drops across the impedance of the mains. This can manifest itself as a Flickering of the lights. The extent to which this is annoying to people is related to the magnitude of the light change and the rate at which it changes. In an attempt to reduce this phenomenon, an international standard IEC61000-3-3, imposes limits on the levels of Flicker which can be induced by a given electrical appliance.
The measurement of Flicker is embodied in the Flickermeter, the instrument which is used for product compliance type-testing. A key part of this regulatory framework is the calibration of Flickermeters. The paper will describe methods of calibration, both in use and under development at NPL.
