(Ground-Fault

Monitor)
Description
The SE-134C/SE-135 is a microprocessor-based,
combination ground-wire monitor and ground-fault relay
for resistance-grounded or solidly grounded systems. It
continuously monitors the integrity of the ground conductor
to protect portable equipment from hazardous voltages
caused by ground faults. The SE-134C/SE-135 is field proven
in monitoring trailing cables on large mobile equipment such
as drag-lines, mining shovels, shore-to-ship power cables,
dock-side cranes, stacker-reclaimers, submersible pumps,
and portable conveyors.
