High impedance differential protection,
single phase
Application
The 1Ph High impedance differential protection function HZPDIF can be used as:
• Generator differential protection
• Reactor differential protection
• Busbar differential protection
• Autotransformer differential protection (for common and serial windings only)
• T-feeder differential protection
• Capacitor differential protection
• Restricted earth fault protection for transformer, generator and shunt reactor
windings
• Restricted earth fault protection
The application is dependent on the primary system arrangements and location of
breakers, available CT cores and so on.
