Over cur. IDMT alarm
DISABLE: If the measurement value of current more than “Over cur. set” parameter and this condition
is go on more than “Over act. delay time” parameter, the unit will give a “Over current” alarm.
ENABLE: If the measurement value of current more than “Over cur. set” parameter and this condition
is go on more than “Tripping time”, the unit will give a “Over current” alarm.
(“Over act. delay time” parameter) x (“Over cur. set” parameter)
(Measured current) - (“Over cur. set” parameter)
Tripping time =
