Purpose of the development: The voltage relay is designed to disconnect the 400V 50Hz load with: unacceptable voltage fluctuations in the network with a duration of at least 0.02s, violation of the amplitude symmetry of the mains voltage (phase distortion), breakage, sequence violation and phase cohesion.

Recommended application field: At the enterprises to disconnect the load 400V 50Hz with unacceptable voltage fluctuations in the network.

Advantages over analogues: Multifunctionality and a large threshold of voltage drops.

The development stage readiness: Ready for application

Description of the development:
()
These products are used for: - control of the permissible voltage level; - control of correct alternation and absence of phase cohesion; - control of full-phase and symmetry of mains voltage (phase distortion); - disconnection of the load at a low-quality mains voltage; - monitoring the quality of the mains voltage after the load is switched off and automatically turn it on after restoring the voltage parameters; - indication of an emergency in the event of an emergency situation and indication of the presence of voltage in each phase. In both products it is possible to adjust the voltage threshold. Relay RNPP-312, in addition has the ability to adjust: - the time of automatic reclosing (AR) and the delay time of the protection operation; - selection of the voltage of the monitored network (400 V or 415 V) and a set of protective functions. After restoring the voltage parameters of the network, the product re-includes the load through the reclosure time.
