Power Flow Without the 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

Know your Power Supply Characteristics

Power supply refers to the electrical charge that runs from the poles, wires and cables on your street to power the machines and appliances in your business.

Supply voltages change constantly – falling as loads are switched on and rising again when they are switched off. This happens on a large scale throughout the entire electricity supply network.

The typical voltage supplied by electricity providers is over the range of 230v-253v (Australia), but usually is around 240v. However, each phase of a 3 phase system differs which causes voltage unbalance.

Although Australian Standards specify that all electrical equipment to be used in Australia must operate between the voltages of 220v and 240v, the electrical equipment may still operate over 240v, but suffer from excess heating issues.

The Beolec Mark 4 has been engineered and manufactured to regulate the incoming power supply voltage ranges to fall within the Australian Standards for the normal operation of electrical equipment.

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. Beovista 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. Beovista can help determine the optimal voltage for your organisation.

The Beolec can regulate down to, and maintain voltage as low as, 220V in Australia/New Zealand, and 255V in the U.S.A.

Installation & Key Benefits of the Beolec

A Beolec solution is a in-series regulator and connects into the main switchboard after the supply authority meter.

The benefits of installing the Beolec Mark 4 into an organisation's electrical system are:

  1. Savings in electricity bills of up to 15%
    • Every 1v above 220v is wasted voltage that is not required
    • Increased power created by higher voltage is paid by the consumer
    • Reducing the voltage means savings in the electricity bill
  2. Less power is consumed in the electrical system as voltage is reduced
  3. Power quality improves as constant balanced voltage is delivered to the electrical infrastructure
  4. Lowered voltage means
    • Lower operating temperatures on motors
    • Reduced long term plant and equipment maintenance
    • Life expectancy of plant and equipment is increased
  5. No risk to existing plant and equipment performance
    • A company’s impact on the environment is reduced as overall carbon emissions are lowered due to less power being required as a direct result of voltage reduction
    • Beolec Mark 4 is modular in design and is easy to install
