Voltage Protection Relay, Rnpp-301

Novatek India Enterprises offers three-phase Voltage Protection Relays, RNPP-301. These are used for protection of three-phase loads against un-allowable mains voltage variations, phase loss, phase imbalance, phase coincidence and incorrect phase sequence. They are highly effective for the protection of any three phase electrical equipment and circuits, including equipment with long term transient dynamics and electric motor load as well as installations where continuous monitoring of quality, availability and three phase lines presence of the mains voltage is required, for example in automatic load transfer panels (ATS-panels). The relay is designed for protection of machinery and circuits, which are most critical to all of the power supply parameters. It has 6 independent adjustable settings for the basic parameters. The benefit of RNPP-301 is a capability of operation within two types of circuits with isolated (3-wire) and solidly-earthed neutral (4-wire) electrical circuits. The relay provides accurate true RMS voltage monitoring and control over the full phase switching of magnetic starter/contactor terminal contacts. Separate front panel LED indication pattern for each type of fault. Use of a complex information processing algorithm allows making different decisions depending the type of a fault and either allow auto reclosing when the power parameters get back to normal or block further operation until the service engineer to come for the problem solution if the fault could not be solved by itself.
