These devices are microprocessor based correctors with LCD display. They are suitable for setting 5 or 7 capacitor groups. These correctors are metering the parameters in one phase and the interference happens accordingly. The switching of capacitor groups is coordinated with the metered capacitor powers and the pre-adjusted full reactive power values. During rating process the switching of the levels follows a complex capacitor metering and power factor determine algorithm according to adjusted power factor value and level, protecting the capacitor groups and the switching contactors from run-down. The device has a potential free alarm output and it is programmable with front panel pushbuttons. The cooling is getting active according to pre-adjusted and memory stored level when the capacitor’s temperature is rising up. The alarm output’s active state is displayed by front panel LED.
