Abstract
A system and method for detecting a flicker of electrical energy provided via a service type to an energy meter. The system comprises a memory for storing a respective voltage threshold for each different service type; a digital signal processor for measuring a respective phase voltage for each meter element of the energy meter; and a microcontroller for retrieving the voltage threshold for the service type from the memory and comparing the measured phase voltage to the voltage threshold to determine an occurrence of flicker.
