Volts Per Hertz; Restricted Ground Fault; Records; Transducer Inputs And Outputs - GE G30 Instruction Manual

RECORDS

Magnitudes of the third harmonic components of the machine neutral point voltage (VN), the zero-sequence voltage at the
machine terminals (V0), and in the vector sum of the neutral point voltage and zero-sequence voltage (VN + V0) are
available for display. The values are calculated for a signal source specified under the
These readings can be useful when selecting a pickup and supervision setting for the third harmonic neutral undervoltage
protection element.
