Automatic Ground Protection Relay Reset (AGPRR)

Wabtec Products Auto Ground Protection Relay Reset (AGPRR)

The Automatic Ground Protection Relay Reset or AGPRR, is designed to provide an automatic means of resetting a locomotive Ground Protection Relay (GPR) under temporary fault conditions, and to lock the GPR out when the fault is of a more permanent nature and might be potentially damaging to the locomotive electrical system. The device is designed for protection against electrical transients, and for stability under wide operational temperature ranges and input voltages.
