For the negative phase sequence directional elements to operate, the device must detect a polarising voltage
abov
e a minimum threshold, I2> V2pol Set. This must be set in excess of any steady state negative phase
sequence voltage. This may be determined during the commissioning stage by viewing the negative phase
sequence measurements in the device.
