•
Adjust the magnitude of Va and Vb while retaining the conditions above and measure the
voltage Va at which the element operates.
•
The theoretical operating voltage is obtained by 2IT

ZOST when the setting reach is ZOST.
Check that the measured voltage is within
±
5% of the theoretical voltage value when it is
expressed with 2Va (= Va
