Energy Saving

Reduced power costs can be achieved by reducing the voltage received and increasing the quality of the power. Captech develop technologies to achieve efficiencies for industrial and commercial high energy users through standardised and customised solutions.

Reduce power consumption and reduce your costs and environmental footprint.


There are real savings to be made

Costs to your business attributed to your power supply can be wide reaching. These costs can be:

  • direct, i.e. high power bills
  • in-direct, i.e. maintenance and repair due to overheating and failing plant and equipment.

Specifically, these can include:

  1. Overheating of transformers, switch gear and cabling
  2. Nuisance tripping of circuit breakers or fuses
  3. Unstable equipment operation
  4. High energy usage and costs
  5. Motor failure
  6. Electrical or electronic equipment failure


The Process

The first step to reducing your power consumption is through energy performance monitoring.

System analysis identifies areas of improvement for greater efficiency and cost savings. Such analysis can include data logging, network modelling, auditing and reporting.

Causes of power related costs

Often costs associated with incoming power issues will relate to poor power quality and voltage issues. Addressing these issues can prevent the above problems from occurring.

Poor Power Factor

Power Factor Correction may be required where a system has a power factor of less than 90% (or 0.9). A poor power factor can contribute to equipment instability and failure, as well as significantly higher than necessary energy cost since it means that more current is required to perform the same amount of work. By optimising and improving the power factor, power quality is improved, reducing the load on the electricity distribution system.

High Voltages or Voltage Instability

Network providers supply power to customers at a higher nominal value than generally required to operate equipment. They do this to ensure that all customers receive acceptable voltage levels taking into account voltage drop and customer loading. This means that the voltage levels experienced are generally higher than that required to efficiently operate equipment, and can results in over voltage issues such as overheating and malfunctions, as well as increased energy costs.

Voltage Optimisation devices are installed in series with the incoming supply and the end user equipment to reduce the voltage down to optimal levels for equipment operation. Further, the ability to adjust the incoming voltage allows for a reduction in some harmonics and transient voltage spikes to ensure a stable and reliable power supply to plant and equipment.
