The necessity to find effective ways to save electricity and apply energy efficiencies due to pressure on South Africa’s power grid is not limited to domestic households but impacts industrial operations, commercial businesses and factory owners alike. We ask: “what can we do to save electricity?”

Through an acute understanding of an industrial electrical network, plant constraints, information gathered from site evaluations and measures taken from historical electrical consumption, Power Factor Correction (PFC) can be an effective way of saving electricity.
Power Factor Defined:
The measurement of Power Factor evaluates how effectively electrical equipment converts an electric current into useful and efficient power output.
Power Factor can is the ratio of Active or Working power (measured in Watts or Kilowatts) to the Apparent Power (measured in volt amperes or kilovolt amperes) of electrical installations throughout plant operations.
How can Power Factor Correction save electricity for factory owners and commercial or business plant operations?
Power Factor correction reduces the total current drawn from an electrical distribution network from the point of power generation to the end user or output, reducing overall demand on electrical utilities.
Business and environmental benefits of Power Factor Correction and the reduction in energy consumption;
  • Improve profit margins
  • Improve competitiveness through improved production efficiencies
  • Improve the economy and related industries
  • Reduce energy and electrical costs
  • Reduce your plants carbon footprint
  • Free up capacity on electrical supply transformers
  • Reduced voltage drop on supply transformers and supply cables
  • Reduced transmission losses
Reducing the total current drawn from an electrical distribution network as well as ensuring electrical equipment effectively converts electrical currents supplied by your power utility, Power Factor Correction improves useful power output while saving your business electrical costs.
Calculate Power Factor Correction 
Calculating the power factor correction requirements and the potential savings that can be accomplished by implementing a power factor correction solution, can be done based on 2 variable scenarios.
Scenario 1: When the current, voltage and power factor of the plant during maximum load conditions is known.
Scenario 2: When the apparent power, power factor and voltage of the plant under maximum load conditions is known.
The collation of information gathered from sophisticated test equipment installed onsite, as well as the review of historical billing information, custom designs taking into account space, ventilation and all other factors influencing the effective installation, result in the most efficient and lowest life cycle costs of power factor correction interventions.
Industrial and commercial businesses that can benefit from applying power factor correction include:
Sawmills, flour mills, etc
Plastic extrusion and recycling industries
Industries that use machine tools, stamping machines, welders and compressors
Foundries and mining units
FMCG industries
Bottling plants
Agricultural Customers
Large industrial and commercial customers
