A device and method are provided for monitoring quality and performance parameters of an electricity distribution component in an electricity distribution network and detecting any deviation of operating parameters from the specified regulatory set and enforced limits. The critical and increasing problem is mitigated for the myriad of private domestic and commercial DEG devices being installed and connected to the distribution networks which were not initially designed for, or even not anticipated with, the recent DEG evolution, and the increasing complex electrical components with changing loads and power factors across the distribution network.
