SE 134C is a microprocessor based combination ground fault and ground wire monitor for resistance grounded systems It has a switching power supply that accepts a wide range of ac and dc voltages and its specifications apply over an industrial temperature range at high humidity The SE 134C meets the IEEE surge withstand capability tests oscillatory and fast transient for protective relays and relay systems Isolated normally open and normally closed contacts are provided for contactor control or for shunt or undervoltage operation in breaker trip circuit operating conditions are clearly annunciated and two Form C contacts are provided for remote indication The SE 134C is housed in an anodized extruded aluminum enclosure and all connections are made with plug in wire clamping terminal blocks Provision is made for both panel and surface mounting The ground fault circuit detects fundamental frequency zero sequence current with a window type current sensor and it verifies that the current sensor is connected and not shorted A definite time characteristic with 11 trip levels and 11 trip times allows coordination in virtually any resistance grounded system Although other current sensors may satisfy the verification circuit only SE CSIO series sensors have characteristics that meet system specifications Current sensor verification can be disabled for a ground check only application The ground check circuit has an open circ
