Introduction: Production of relays and identification of protection settings to be used in network protection schemes, which enable the protection to function nominally when subjected to a range of disturbances, which may be found on current and future distribution networks.

Objectives: Testing will be carried out on a range of loss of mains relays in order to develop a clear understanding of the stability of these relays when confronted by a range of network disturbances applied at a range of relay settings.

This information will be used to develop a matrix of optimum settings and test procedures for relay specification.
