Fault locator for overhead lines Schweitzer Engineering Laboratories
Self-adjusting fault indicator for system-wide application. Provides clear visual indication of fault path to line crews in the field to help reduce fault-locating time. Automatically adjusts its trip value based on the load current, eliminating the need to specify a trip value. Allows line crews to easily distinguish between temporary and permanent faults. The inrush restraint feature allows coordinated integration with automatic reclosing schemes. Patented Ramp Down Restraint feature prevents false activation after extended circuit outage. Distinct eight-hour temporary fault indication allows line crews to investigate the cause of self-clearing faults and successful trip and reclose operations to improve circuit reliability.
