CONTROLEUR D'INTERFACE PROGRAMMABLE

摘要

A programmable interface controller (30) for testing operation of a protection relay (33). The controller (30) is coupled between a test instrument (32) and the protection relay (33) under test and provides selectable test circuit path configurations for testing the relay (33). A computer (31) is coupled to the test instrument (32), the protection relay (33) and to the controller (30) for monitoring operation of the controller (30) and for providing signals to the controller (30) to allow it to establish the test circuit path configurations. The controller (30) is also operable to allow manual selection to test circuit path configurations.
