  • Measurement principles
    • High current and power factor measurement accuracy is achieved by utilizing digital signal processing using a microprocessor and FFT algorithm.
    • Precise measurement and control functions even under conditions of voltage or current waveform distortion by higher harmonic components.
  • Control principles
    • Governor's speed of response independently programmable for conditions of undercompensation and overcompensation, respectively.
    • The preset speed of response increases in proportion to instantaneous control deviation, that is by square of the ratio of the control deviation to the smallest capacitor section value (C/k); growing control deviation may reduce this value to minimum control time of 5 seconds.
    • If the control deviation is smaller than the smallest capacitor section's current (C/k), the preset control response time gets longer twofold; if the control deviation keeps decreasing under a half of the smallest capacitor section's current (C/k), no control takes place
  • Automatic installation
    • Automatic connection detection on governor installation
    • Automatic control section recognition
    • It is possible to connect any combination of the control sections
    • Section value manual entry possible
  • Alarm with free program
    • independently adjustable alarm's signaling and action functions function of the 6th relay programmable to alarm signalling
