VarSet Low Voltage Capacitor Banks reduce overall kVA demand

  • Optimise energy consumption
  • Increase power availability
  • Improve business performance
Johannesburg South Africa, 15 April 2019
Schneider Electric’s range of VarSet Low Voltage (LV) Capacitor Banks form part of the company’s Power Factor Correction solutions that modify and control reactive energy. In electrical networks, reactive energy results in increased line currents for a given active energy transmitted to loads. The main consequences are:
  • Need for oversizing of transmission and distribution networks by utilities
  • Increased voltage drops and sags along the distribution lines
  • Additional power losses
This results in increased electricity bills for industrial customers because of:
  • Penalties applied by most utilities on reactive energy,
  • Increased overall kVA demand,
  • Increased energy consumption within the installations.
Reactive energy management aims to optimise electrical installation by reducing energy consumption, and improving power availability. Total CO2 emissions are also reduced and utility power bills are typically reduced by 5-10%.

The complete range of VarSet Easy LV Capacitor Banks, for fixed and automatic compensation, assists in balancing for reactive power and harmonic distortion. This provides an easy and efficient solution to quickly maintain a facility’s power factor at an ideal level for maximum system efficiency.

Benefits of reactive energy management
Optimised reactive energy management brings economic and technical advantages:
  • Savings on the electricity bill
  • Eliminating penalties on reactive energy and decreasing kVA demand
  • Reducing power losses generated in the transformers and conductors of the installation.
  • Increasing available power
  • Reducing installation size
  • Reducing voltage drops in the installation
As a result of Power Factor Correction and Reactive Power Compensation solutions, facilities in the retail and healthcare space, office buildings, hotels, pumping stations, small packaging as well as small industrial facilities can benefit from tangible return on investments (ROI).

These include reduced capital expenses of up to 30%, owing to optimised electrical system capacity. Further ROIs includes the reduction in losses of transformers and conductors and optimised energy consumption, which helps in reducing CO2 emissions.

Varying solutions
The objective of reactive energy management is improvement of power factor, or ‘power factor correction’. This is typically achieved by producing reactive energy close to the consuming loads, through connection of capacitor banks to the network.

The VarSet De-tuned Automatic Capacitor Banks form part of an anti-resonant power factor correction system that helps in providing power factor correction in electrical distribution networks, where moderate harmonic content exists.

Schneider’s VarSet Standard Automatic Low Voltage Capacitator Banks are ideally suited for power factor correction in applications where plant loading is constantly changing. This makes it flexible and effective reactive power compensation system in low-voltage networks, where current and voltage harmonic distortion levels are minimal.

The VarSet Fixed Power Factor Correction Capacitator is ideally suited for applications where the load does not change. It is also ideal for situations where the capacitor is switched with the load, such as the load side of a motor starter.

VarSet provides the features and capabilities needed for power factor correction and improvement. Users can select from a full range of standard, pre-configured capacitor banks or alternatively build a custom solution by mixing available options to fulfil their unique requirements. The VarSet range of LV Capacitor Banks are fully type tested in compliance with IEC/EN 61439-1 & 2, IEC 61921 standards.

All components and solutions are available through a network of distributors and partners in more than 100 countries, including South Africa.
