3.4.4. Measured E/F
Description
Gn 51G/50G Measurement
Selects whether the RMS value used by the 51G & 50G
elements is True RMS or only calculated at fundamental
frequency

Description
Gn 51G-1 Element
Selects whether the 51G-1 IDMTL measured Earth Fault
element is enabled
Gn 51G-1 Setting
Pickup level
Gn 51G-1 Char
Selects characteristic curve to be IEC or ANSI IDMTL or DTL
Gn 51G-1 Time Mult (IEC/ANSI)
Time multiplier (applicable to IEC and ANSI curves but not
DTL selection)
Gn 51G-1 Delay (DTL)
Delay (applicable only when DTL is selected for characteristic)
Gn 51G-1 Min Operate Time
Minimum operate time of element.
Gn 51G-1 Follower DTL
Additional definite time added after characteristic time
Gn 51G-1 Reset
Selects between an ANSI decaying reset characteristic or DTL
reset
Gn 51G-1 Inrush Action
Selects if the 51G-1 element is blocked from operating when
2nd Harmonic Inrush Detector operates
