Summary

JKW series intelligent reactive power automatic compensation controller is suitable for the automatic adjustment of capacitor compensation device in low-voltage distribution system (hereinafter referred to as controller), which makes the power factor reach the user's predetermined state, improves the utilization efficiency of power transformer, reduces line loss and improves the voltage value of power supply, thus improving economic and social benefits.

JKW series controllers combine power factor and reactive power, which not only keeps the operation of power factor mode simple, but also solves the problem of switching capacitor banks in power factor mode without switching oscillation, and is suitable for three-phase balanced working environment, especially when the load is light and the capacitance is large. .
