SC14S Instantaneous Earth Fault Relay

1 phase High Impedance Earth Fault Relay

SC14S is a self-powered, single-phase, non-directional, Earth fault relay with one measuring element.

Salient features

• Micro-controller based design
• Draw out facility
• Built in Third Harmonic Filter.
  It helps to avoid spurious tripping in harmonic rich power systems
• Instantaneous time delay or delay of 100 ms, 200 ms can be set

Current Input: 1A / 5A

Application

The relay can be used for differential protection of generators, REF applications of generators and transformers in all low voltage, medium voltage sub-stations.
