Admittance
Neutral Admittance
The effective operating quantities of the Neutral Impedance elements are displayed here.
Path: Metering > Admittance > Neutral Admittance 1[X]
Ntrl Admit Mag
Range: 0.00 to 230,000.00 mS in steps of 0.01 mS
Default: 0.00 mS
This value represents the magnitude of the neutral admittance seen by the relay.
Ntrl Admit Angle
Range: -359.9° to 359.9° in steps of 0.1°
Default: 0.0°
This value represents the angle of the neutral admittance.
Ntrl Conductance
Range: -230,000.00 to 230,000.00 mS in steps of 0.01 mS
Default: 0.00 mS
This value represents the magnitude of the neutral admittance seen by the relay.
Ntrl Susceptance
Range: -230,000.00 to 230,000.00 mS in steps of 0.01 mS
Default: 0.00 mS
This value represents the magnitude of the neutral susceptance seen by the relay.
