Note for Voltage tests the Voltage required to trip is the setting ±3.45V. The time delay can
be measured at a larger deviation than the minimum required to operate the protection. The
No trip tests need to be carried out at the setting ±4V and for the relevant times as shown
in the table above to ensure that the protection will not trip in error.
