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.

Dispositif de commande (30) d'interface programmable destiné à tester le fonctionnement d'un relais de protection (33). Ledit dispositif de commande (30) est couplé entre un instrument (32) de test et le relais de protection (33) testé et fournit des configurations de trajet de circuit de test pouvant être sélectionnées pour tester le relais (33). Un ordinateur (31) est couplé à l'instrument de test (32), au relais de protection (33) et à l'unité de commande (30) en vue de surveiller le fonctionnement de l'unité de commande (30) et de fournir des signaux à ladite unité de commande (30) pour lui permettre d'établir les configurations de trajet de circuit de test. L'unité de commande (30) peut également fonctionner pour permettre la sélection manuelle de configurations de trajets de circuit de test.
