technology without beolec

Without the introduction of a Beolec system into the premises, the electrical infrastructure is susceptible to all Supply Authority Power Quality Issues:

  • Spikes
  • Voltage unbalance
  • Emerging evidence that high penetration of solar PV (Photovoltaic) is already causing voltage rise beyond the statutory limit of 400 V + 10% (253 volts phase to neutral) in particular parts of the energex network [Refer: Energex Publication DAPR 2013/14 to 2017/18]
  • Over voltage
  • Waveform distortion


technology with beolec

With the introduction of a Beolec system into the premises electrical infrastructure the customer receives the following key benefits:

  • Voltage regulation is maintained to a fixed nominal output set-point (e.g. 220V) +1/ -1 volt of the set-point
  • Voltage is actively independently balanced across all three phases and is maintained to +1/ -1 volt of the set-point
  • Brings voltage to the lower level of equipment design specifications (i.e. 216.5V- 253V)
  • No introduction of harmonics into electrical system
  • Lower voltage stress means reduction in maintenance and associated costs Real time monitoring through internet based software enable load profiles to be generated for critical analysis
