Supporting Information
- Continuous NGR monitoring detects resistor failure within seconds, reduces transient overvoltage risk, removes risk of ground fault detection failure|Ground fault detection main or backup protection to detect a ground fault anywhere on the monitored system|Adjustable pickup (2 to 100%) selects greatest sensitivity without false operation, adjustable in 1% increments (MEM setting)|Adjustable trip delay allows quick protection and system coordination|Universal CT compatibility allows the use of a CT that gives required ground fault settings|Selectable fail safe or non-fail safe operating modes allows connection to shunt or undervoltage breaker coil or alarm circuit (trip, ground fault, resistor fault relays)|Trip records onboard 100 event (with date and time) recorder helps with system diagnostics|Harmonic filtering (DFT) eliminates false trips due to harmonic noise from ASDs|Local communications mini USB port to view measured values, configure settings and check event records|Onboard microSD card can be used for long term data logging|Selectable latching or auto reset operation|Unit healthy output verifies SE-330 is operating correctly|Internal circuits are conformally coated to protect against corrosion and moisture|Normally closed K4 unit healthy contact|USB only communications
