The SE-105/SE-107 is a combination ground-wire monitor
and ground-fault relay for resistance-grounded systems. It
continuously monitors the integrity of the ground conductor
to protect portable equipment from hazardous voltages
caused by ground faults. The SE-105/SE-107 is an excellent
choice for trailing cables 5 kV and under in underground mining
applications. For higher voltages or long-cable applications, see
the SE-134C/SE-135.
