Woodward IRI1-I5E05D Earth Fault Relay

FAQ

Q1: What type of ground fault conditions can this relay detect?
A1: It detects leakage currents caused by insulation failure, cable damage, or unintended grounding paths in power systems.

Q2: Can the relay be adjusted for low-level earth leakage detection?
A2: Yes, sensitivity can be set as low as 0.1 A to detect early-stage insulation faults.

Q3: Does this relay support inverse time protection curves?
A3: Yes, it provides IEC inverse time characteristics to coordinate with upstream and downstream protection devices.

Q4: How does the relay reduce nuisance tripping?
A4: Adjustable time delay and filtering prevent momentary ground transients from triggering false trips.

Q5: Is this relay suitable for both AC and DC auxiliary supplies?
A5: Yes, it accepts a wide-range AC/DC auxiliary power input.

Q6: Can the relay provide both alarm and trip signaling?
A6: Yes, it includes separate output contacts for alarm and trip functions.

Q7: How is fault status indicated?
A7: LED indicators on the front panel display operating condition, trip status, and power presence.

Q8: Can the relay be integrated with protection panels and PLC systems?
A8: Yes, its relay outputs allow seamless integration with control circuits, annunciators, and automation systems.
