Power System Protection


We specialise in the protection of substations, power stations as well as various industrial and mining electrical equipment.

We design, manufacture, test and commission complete tailor-made protection and control solutions using the latest technologies from low or medium-voltage applications to state-of-the-art modern EHV (Extra High Voltage) protection (schemes) systems (From 400V to 765kV systems).

We are active in the following industries:

  • Large Utilities (Eskom Holdings SOC, Copperbelt Energy PLC, Zesco, etc.)
  • Metros and Municipalities (éThekwini Electricity, City Power, City of Tshwane, etc.)
  • Mining (Harmony Gold, Xstrata, Foskor, De Beers, etc.)
  • Industry (Sasol Limited, Natref, Rand Water Boardetc.)
  • Other Large Power Users
  • Power Stations

Apart from fully integrated protection and control solutions (ICAP), we design and manufacture complete systems: from medium-voltage applications to state-of-the-art modern EHV protection schemes. These may incorporate the latest high-speed algorithms required to maintain stability of modern transmission and distribution systems, and full dual-main protection systems, as may be required by the customer and/or end user.

Our manufactured protection solutions and integrated systems are able to ensure visibility and control of the power system or plant equipment using the latest standard industry protocols, both locally and remotely (via a substation gateway or Remote Terminal Unit)
