Application
ZMCF series reactive power automatic compensating controller (hereinafter referred to as ZMCF) is applicable for the automatic adjustment of capacitor compensating device of low voltage distribution system. With power factor up to the user's presetting state, it can improve the utilization efficiency of electric power transformer, reduce the wire loss and improve the voltage quality.
Function characteristic
1.Calculate the capacitor capacitance by the fundamental wave reactive power, avoid the switching oscillation in any form. Correctly display the grid power factor under harmonic wave.
2.High measurement accuracy of power factor, wide range of display.
3.Real-time display of total power factor(PF).
4.Real-time display of voltage distortion factor and current distortion factor
5.Friendly human-machine interface, for convenient operation
6.Various control parameters, by digital display, very visual and convenient to use.
7.Two working modes: automatic and manual Over/under voltage protection
8.Protection against the impermissibly high voltage harmonic wave
9.Data is not lost due to the protection against the power failure
10.Low input impendence of current signal: ≤0.01Ω
