RNPP-302M numeric voltage monitoring relay is designed for protection of three phase loads against major type of mains faults, as:
- RMS voltage reaching beyond admissible thresholds - over and under voltage
- Phase loss or Single phasing
- Phase sequence order violation or reverse phase sequence
- Phase coincidence or shorting of two or more phases
- Phase Imbalance or asymmetry
- Contactor output side monitoring - full phase switching, contactor health
The device performs monitoring the main circuit parameters and de-energizes (trips) load when the parameters fall beyond specified boundaries.
The three digit, seven segment LED display on the relay front panel allows to:
- Continuously indicate the true RMS circuit voltage - phase voltage or line voltage
- Indicate type of occurring fault
- View (visualize) settings of modes and programming parameters
The menu allows the user to make the following settings:
- Mode of voltage indication for each phase
- Mode of the relay reaction to the digital input for remote de-energizing (tripping)
- Type of relay - phase voltage or line voltage
- Method for setting the voltage deviation
- Turn on/off the phase imbalance monitoring
- Turn on/off the phase sequence order monitoring
- Contactor output terminals voltage monitoring
- Type of measured voltage - 220/380 V, 230/400 V, 240/415 V selectable
- The maximum allowable voltage tripping threshold
- The minimum allowable voltage tripping threshold
- Allowable phase imbalance threshold - %
- Automatic reset delay time
- Min voltage de-energize (tripping) delay time
- Max voltage de-energize (tripping) delay time
- Phase imbalance tripping delay time
- Phase loss tripping delay time
- Delay time for tripping upon a digital input (external emergency button input)
- Monitoring of full phase switching of contactor (output side monitoring)
The device is equipped with an additional alarm/annunciation relay with normally open contacts lead out.
