Hi-Tech, microprocessor based correctors with LCD display. They are suitable for setting 7 or 12 capacitor groups. These correctors are metering the parameters in one phase and the interference happens accordingly.
The value and the style of power ratio, the phase current and voltage, the voltage harmonics, the capacitor’s temperature and the number of switched capacitor groups are displayable. On manual state the user can control the number of capacitor groups. During testing process the connected levels and the level’s reactive power ratio is defined automatically. In automatic mode, the switching of capacitor groups takes place according to needed capacitor power and pre-adjusted parameters.
During rating process the switching of the levels follows a complex 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.
