| Overview |
Use SEL fault counters (FCs) as troubleshooting devices on overhead lines. FCs identify the location of recurrent faults caused by defective insulators, tree branches, worn sections of line, etc. The device, which indicates with a reflective red pointer set in a clock-style face, counts up to ten faults. Manually resetting the FC with a magnet tool (the FCRT) returns the pointer to the “zero” position.
