Control & Protection Devices

MACHINEWATCH

Mining & Industrial Motor Control

The MachineWatch (X0270) is a complete Motor control safety system in one box.

BELT SLIP AND SPEED RELAY

Mining and Industrial Equipment Monitor of Belt Slip and Speed

The NEPEAN Power Belt Slip & Speed Relay measures slip between a driven roller (input S1) and two other rollers (inputs S2 & S3). Alternatively, our Belt Slip & Speed Relay can measure the slip of one roller from its normal run speed. Our device will then provide the maximum slip measurement (0-50%) on a 4-20mA output.

EDDY CURRENT COUPLING CONTROLLER

Control of Eddy Currents

NEPEAN Power Eddy Current Coupling Controller is suited to eddy current coupling coils.

OVERLOAD RELAY

Monitor of overloads

The Overload Relay monitors short circuit, overload, under current and temperature in the protected circuit and trips to ensure safe operation in industrial and mining environments. Our Overload Relay also detects faults with the current transformers used.

LIVE LINE INDICATOR

Monitor of live lines

The Live Line Indicator uses a non-contact method for sensing the presence of voltage on a phase and indicates the presence or absence via several LED’s.

There are three LED’s, one for each phase (marked A, B, and C) to indicate if voltage is present on each particular phase. Each LED flashes to indicate voltage is present on its specified phase.

PHASE LOSS & ROTATION RELAY

Phase rotation monitor

The NEPEAN Power phase loss and rotation relay unit has been designed for use with power systems and rotating machines where the possibility of incorrect phase rotation exists. Phase rotation and phase loss are constantly monitored and reported using LEDs on the front panel and relay contact outputs.

FLAG RELAY

Mining & industrial equipment protection

Our Flag relays provide a latching that can be reset mechanically or electrically when required.

CURRENT TRANSFORMER

Protection of electrical equipment

The NEPEAN Power MSQ Series Current Transformers can be applied to test, control, display and record the running of electrical equipment and to protect equipment against damage. They provide the necessary means to measure the actual load current and reduce its values by means of a transformation ratio to a manageable value. The Current Transformer is mounted into a case of PPO flame retardant material.

NEUTRAL EARTH RESISTOR MONITOR

Monitor of Neutral Earth Resistor

The NEPEAN Power Neutral Earth Resistor Monitor (NERM) is designed to monitor the integrity of the neutral earth resistor and its connection between the neutral point of the transformer and earth.
