Function Characteristic
ZMGY-2 high voltage reactive compensation controller adopts the combination of inverse time lag and timing technology, controls the switching operation of the capacitor through setting the capacitor capacity and reactive power calculation.
Hereinto, the inverse time lag technology can effectively guarantee the smoothness of capacitor operation, to avoid the electric appliance’s frequent switching operation or concussive switching operation due to fluctuation and abrupt change of voltage. In addition, to further prevent the capacitor from frequent operation and concussive switching operation, the controller will give an estimation according to the capacity of the capacitor, to guarantee the capacitor can’t conduct the opposite operation after it operates if the system is in the abnormal area.
