July 14th, 2016, Published in Articles: Energize


Reactive Power has rapidly advanced to become the leading MV power factor correction and harmonic filtering supplier in Southern Africa. It is based in Johannesburg and operates throughout the Southern African region.

The company has served the electrical industry for many years, going back to the late 1980s. In the last five years it has supplied over 162 harmonic filter banks and shunt capacitors from 3,3 to  275 kV. The company has the necessary skills to provide full turnkey projects. The design capabilities available to Reactive Power range from 400 to 3,3 kV complex filters. The majority of projects however are found in the mining and industrial segment, with various projects being undertaken from 6,6 to 33 kV. The company also services and re-commissions various installations from 6,6 to 33 kV. Furthermore, it supplies a number of projects into Southern Africa, where its clients include all the major mining houses as far afield as Ghana and Burkina Faso. The company’s experience gives customers the assurance that its solutions will not only be of the highest technical standard but will also be cost competitive and provide the best solution for their needs. Reactive Power has in-house professional engineering skills ensuring a professional approach to any project with the highest technical standard. It has a wide variety of designs available to suit customers’ needs.

Reactive Power is also active in the FACTS area and, with its relationship with AMSC, the company can now supply SVC’s, STATCOM’s and other power quality devices.

AMSC’s Reactive Power Solutions offers proven technologies that facilitate renewable energy integration, strengthen the security and reliability of the transmission and distribution grid and allow industrial customers to maintain peak productivity. AMSC’s D-var STATCOM, can precisely and quickly deliver reactive current to mitigate voltage transients and deviations that can adversely affect the performance of the grid and industrial machinery. The D-SVC, a direct-connect distribution SVC, allows industrial businesses to utilise a plant level solution to mitigate power quality problems such as voltage sags due to large motor starts and voltage flicker. AMSC’s reactive power products are a cost effective solution versus traditional transmission and distribution upgrades and are flexible and customisable to meet client requirements. AMSC’s network planning team is proficient on all the major utility modeling software (including Eskom) and can work with you to analyse your system and offer cost effective solutions to strengthen your power and energy portfolio.

AMSC’s D-var STATCOMs and D-SVCs have been the preferred reactive power solution in many wind and solar farms, transmission and distribution utilities, various mines, semiconductor chip manufacturing facilities and other industrial applications, with more than 215 systems sold.
Reactive Power also maintains outstanding relationships with its sub-suppliers resulting in benefits which are passed onto its clients. This is particularly important when fast delivery or unusual designs are required for a particular situation.

The company offers the following services:

  • Design and supply of specialised harmonic filters of all kinds.
  • Automatically switched multi-step medium voltage bulk power factor correction systems.
  • FACTS devices including SVC’s, STATCOMs, etc.
  • PCB capacity or replacement/refurbishment programmes.
  • Distribution compensation solutions including pole-top shunt banks, ground mounted mobile shunt banks and unconventional substation compensation schemes.
  • Individual motor unit capacitors.
  • Spare or replacement capacitors.
  • Air-cored and iron cored filter reactors.
  • High voltage damping/filter resistors.
  • Current limiting, fault limiting or neutral earthing reactors.
  • Switchgear and integrated control and protection systems for capacitor banks including retro-fitments and upgrading of automatic control and protection schemes.
  • Maintenance, refurbishing and upgrading of all reactive power compensation schemes including the outsourcing of routine maintenance.
  • Remote system monitoring and automated fault annunciation and call-out schemes.
  • Automated remote check metering schemes, utility billing audits and tariff impact studies.

Reactive Power takes pride in creating customer satisfaction and providing projects on time and within budget. It treasures its relationships with its clients and strives to constantly exceed their expectations thereby guaranteeing successful projects and repeat business.
