3.26 Residual Voltage Element (Volt1P)
3.26.1 Application
Residual voltage element is responsible for pre-processing residual voltage and calculating the
magnitude and the phase angle of residual voltage, etc. All calculated information of three-phase
voltage element is for the protection logic calculation
3.26.2 Function
Residual voltage element has following functions:
Pre-process measured residual voltage.
