SDG TECHNOLOGIES :: ELECTRONIC MANUFACTURING AND DESIGN

Designing and manufacturing of power system related electronics, has been the core focus of SDG Technologies since 1999.

Electronic/ power projects done, include:

• 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)
• The distributed frequency monitoring and waveform reconstruction system used to control the frequency of South Africa’s power grid from the ESKOM National Control center.
• 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 centers.
• More information on Metering Software is available here.
