Calibrating electrical analysis equipment. Researcher calibrating a harmonics and flicker analysis machine (not seen). Harmonics are the electric voltages and currents that emerge in the electric power system in response to electric loads. Flicker is the increase and decrease in voltages caused by changes in electric loads. In lamps, flicker is seen as a brightening and dimming of the bulb. Photographed at the National Physical Laboratory, in Teddington, UK.
