Apply nominal 3 phase balanced voltage. Increase the voltage such that the a-b voltage is 110% of the Voltage
setting
Gradually increase the a-b phase current or balanced 3P current until Pickup LED operates. Confirm result of
Phase O/C test above.
Reduce the applied voltage to a level such that V
Gradually increase the I

Note that these elements may be set as directional. If this is the case, the phase angle of the current must be set
with respect to the voltage to produce operation of the elements.

2.4.1.1 Element Blocking
The Voltage Controlled Overcurrent function can be set to Inhibit for VT Supervision operation. This functionality
should be checked. Apply balanced voltage and current. Reduce a-phase voltage to cause a VTS condition.
Increase 3P current until the element operates at its full setting, i.e. 51V settings are not used.
