Protection Relays and Controls Ground-Fault ProtectionGrounded Systems SE-701 SERIES (PGR-5701) Ground-Fault Monitor Description The SE-701 is a microprocessor-based ground-fault relay for resistance- and solidly-grounded systems. In addition to common systems, it is uniquely suited for use on systems with significant harmonic content. The SE-701 can provide main-plant protection, feeder-level protection, or individual-load protection. Proper current transformer selection provides the desired pickup range. The output contacts can be connected for use in protective tripping circuits or in alarm indication circuits. The analog output can be used with a PLC or a meter. Features & Benefits FEATURES BENEFITS Adjustable pickup Trip setting based on input CT primary, allows use with (1-99%) any CT. Minimum 50 mA with EFCT Series. Adjustable time delay Adjustable trip delay allows quick protection and system (50 ms - 2.5 s) coordination Form A and Form B ground-fault output contacts for Output contacts operation of separate annunciation and trip circuits Analog output Allows for connecting an optional meter (PGA-0500) or a (0 - 5 V) control system Simplified Circuit Diagram CT-Loop monitoring Alarms when CT is not connected Selectable DFT or peak Compatible with variable-speed drives A CT detection filtering A Harmonic filtering Eliminates nuisance tripping Non-volatile trip Retains trip state while de-energized to simplify GROUNDED B memory troubleshooting SUPPLY Microprocessor based No calibration required, saves on maintenance cost C Allows operation in application where one side of PT is Universal power supply faulted, provides flexibility for numerous applications Accessories Ground-Fault Current Transformer A Required current transformer model depends on SE-701 SERIES application. We offer a variety of sensitive CTs with (Ground-Fault Monitor) L1 5- and 30-A primaries. L2 PGA-0500 Analog % Current Meter Optional panel-mounted analog meter displays ground-fault current as a percentage of the CT primary rating.
