Detailed Product Description

OCS D1 - The 1 Phase Current Monitoring Relays meaure current through 1A or 5A external current transformer (CT) for under & over current conditions. The setting range covers 50% to 140% of input CT rating.
D2 EFR1 - The Earth Fault Relay is best suitable for monitoring Earth Faults conditions for Motor / Pump loads with selectable setting range from 100mA to 5 A. These are used with CBCT or 3 Normal CTS.
For Monitoring Line frequency variations or for monitoring generator over speed the frequency relays are best suitable for Under / Over frequency conditions.
For monitoring the reverse flow of power from the Generators or when motors act as Generators Reverse Power Relay - RPT D2 / RPF D2 find the application. They sense the direction of power by sensing the reverse current.

To monitor NO load or Under / Over Power conditions of Pumps or Motors or & Power Monitoring Relays - PMR D2 are to be used. It is best suitable for balanced 3 Phase 3 Wire Pump loads for No Load or
