50N: Instantaneous Earth Fault Relay
50G: Instantaneous Ground Fault Relay
- 50N is main EF protection device but 50G is standby as backup of main device.
- 50N use for motor starters but 50G use for feeders.
- 50N see zero sequence of EF current but 50N see residual current due to sum of three CT.
- If you have a resistance grounded system, a 50N may not see enough ground current to trip properly. If you do not have a resistance grounded system, a 50G may create nuisance tripping.
