This section is for Briefly about directional overcurrent
Directional overcurrent will check
1. Polarizing and
2. Magnitude of the Fault current.
Polarizing
• we can take polarizing Voltage (Vpol) only
• we can take polarizing Current (Ipol) only
• for some case both Vpol and Ipol is considered
Type of Directional Element.
i) Forward directional &
ii) Reverse directional
