Why Voltage Optimisation?

Approximately 70% of buildings in Australia receive electricity at a higher voltage than they need.

The allowable voltage range in Australia is 216-253 volts (AS60038). Due to the nature of the electricity grid, most buildings receive voltage on the higher end of this range.

Voltage Optimnisation

What this means for your organization

Electrical supply of low voltage is delivered within Australia at a nominal voltage of 230/400 Volts, with tolerances of -6% to +10% of the nominal voltage (in accordance with AS 60038), within New Zealand at a nominal voltage of 230/400 Volts, with tolerances of -6% to +6%, and within the United States of America at a nominal voltage of 277/480 Volts, with tolerances of -10% to +5% (in accordance with ANSI C84.1 – 2016).

All equipment used within a circuit in Australia, New Zealand and the U.S.A. is required to operate within these tolerances. What this means for your business is that all equipment within the circuit should operate between a bandwidth of 216.5V – 253V in Australia, 216.2V – 243.8V in New Zealand and 249V – 291V in the U.S.A. at the same levels of performance.

The Beolec solution was developed to reduce voltage at the demand side. Quality Energy typically sets the set-point to 220V output in Australia and New Zealand, and to 255V output in the U.S.A. to ensure that the operational voltage sits within the tolerances of the equipment within the circuit and the equipment rating plate by removing this.

The Beolec can help your organisation save money on your electricity bills by reducing and maintaining the supply voltage to the electrical system, to remain within relevant standards. Quality Energy can help determine the optimal voltage for your organisation.

When is Voltage Optimisation Suitable?

Voltage Optimisation provides many benefits, however it is not right for all clients and all buildings. There are important factors that need to be taken into account on every project to determine if voltage optimisation is suitable.

POWER FLOW WITHOUT THE BEOLEC

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

POWER FLOW WITH THE 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
