About SDG Technologies

SDG Technologies has been established in 1999 by Paul van Zyl, an electronic engineer known for his knowledge both in the electronic and electrical fields. In 2009, a working agreement was made with Marinus van Zyl, head developer of the PnP Scada System. In the metering field, SDG Technologies focusses on the hardware for AMR systems while Marinus and his team does the software development to make AMR possible.

  • Supply of hardware and software for the interface of electricity metering with SCADA system in a factory environment (130 000kVA)(2009)
  • Supply of hardware and software for electricity metering and communication in a mixed occupation (residential and offices) development (reducing 7000kVA to 4500kVA with load management)(2009)
  • Specialized opto-coupler units for interfacing Digital Fault Recorders (DFRs) to the protection panels protecting the highest voltage power lines in South Africa. (765kV, 400kV and 275kV typically.)
  • Distributed remote terminal units counting the metering pulses in some of the largest high density metering sites in South Africa, for example Menlyn and Greenstone shopping centres.(2009 – 2012)
  • Install 3 Mill Safe Start units in Ghana at the Tarkwa and Damang mines. (2010-2011)
  • Supply hardware and accompanying software to switch off lighting in shops of the EDCON group at night to save power. The switching units are known as Building Management Remote Terminal units (BMSRTUs) and the software to remotely control these units, is incorporated in PnP Scada. (2013)
