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, stackerreclaimers, submersible pumps, and portable conveyors.
Features & Benefits
Adjustable pickup (0.5-12.5 A for SE-CS10) (2 - 50 A for SE-CS40)
Unit can be used on a wide variety of trailing cable applicationsAdjustable time delay (0.1-2.5 s)
Adjustable trip delay for quick protection and system coordinationOutput contacts
Separate annunciation of ground-fault and groundcheck faultsGround-check LED indication
Indication of open or short ground-check wire makes it easier to find faultsCT-loop monitoring
Alarms when CT is not connectedHigh-induced-ac rejection
Makes unit suitable for applications with high voltages and long cablesDFT (Harmonic) filter
Prevents false operationZener-characteristic termination assembly
