This paper analyses the influence of current harmonics on protections devices connected to the power system which can cause serious problems. This paper outlines work that has been conducted to test of overcurrent relay and to identify the impacts of harmonics on distribution utility protection and control systems. The overcurrent relay REJ 525 is based on a microprocessor environment. A self-supervision system continuously monitors the operation of the relay.
