Relay Monitoring Systems

Relay Monitoring Systems Pty Ltd (RMS) is an Australian owned and operated company dedicated to the design, manufacture and distribution of high quality protective relays and accessories including:

• Auxiliary and tripping relays
• Single and multi-function protection relays
• Trip circuit supervision relays
• Arc fault protection relays

With over 45 years of experience, RMS offer a broad base of field-proven product standard products with rapid delivery. Also available are one-off customised products.

Arc Fault Monitoring Arc fault monitoring offers a method of very rapid clearance of faults within metal clad switchgear and associated cable boxes. Sensors detect the optical signature of the onset of an arc fault and a trip signal can be achieved within 10 ms, considerably faster than traditional IDMT overcurrent relays – especially as the onset of an arc fault can occur at relatively low fault currents. Multiple sensors and zones can be configured to trip feeder, bus coupler or incoming breakers as required. More info on the 1S20 More info on the 1S25
Trip Circuit Supervision Simple, low-cost trip circuit supervision relays offer a standard approach for detection of trip coil, trip wiring and trip relay problems. These simple to install products offer alarm relay outputs, thus eliminating the need for custom built solutions where multifunction relay I/O is not available. More info on the 1X series
Pilot Wire Supervision Compatible with SOLKOR series of pilot wire protection relays, RMS offer a cost effective method of pilot wire supervision and intertrip capability. More info on supervision 3A400 More info on intertrip 3A300
