Protection Relays & Controls Trailing Cable ProtectionGround-Fault Ground-Check Monitoring SE-105, SE-107 SERIES Ground-Fault Ground-Check Monitor Description 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. Features & Benefits FEATURES BENEFITS Adjustable pickup Unit can be used on a wide variety of trailing (0.5, 2.0, 4.0 A) cable applications Adjustable time delay Adjustable trip delay for quick protection and (0.1 - 2.0 s) system coordination Harmonic filter Prevents false operation Zener-characteristic Simplified Circuit Diagram Provides reliable ground-check loop vericfi ation termination assembly Ensures ground-check circuit remains safe TRAILING A Fail-safe ground-check circuit CT CABLE even in the event of equipment failure A Additional coating protects circuit boards GROUNDED B Conformal coating M against harsh environment SUPPLY C SE-105: Selectable UV- or Provides flexibility for different applications shunt-trip mode GC Eliminates chance of unauthorized change to SE-107: UV-trip mode only G trip circuit TERMINATION DEVICE SE-105 SERIES Accessories B SE-107 SERIES CT200 Series Current Transformer A (Ground-Fault L1 Required CT detects ground-fault current.
