10KV 2000kva 3000kva 5000kva 3 phase automatic step voltage regulator
10KV 3 phase automatic step voltage regulator automatically adjust the gear of on-load tap changer according to the condition of circuit voltage to realize the change of transformer ratio, so as to ensure that the output voltage is stable in a certain range. It can be widely used in power supply circuit with long distance of power supply, large power supply load, large voltage fluctuation and power quality can’t meet the usage standard.
