The term Smart Grid is most commonly defined as an electrical grid that has been digitized to provide two-way communication between producers and consumers. The goal of the Smart Grid is to upgrade the electric power infrastructure to include more advanced communication, control and sensor technologies, with the hope of increasing interaction between consumers and power producers. Potential benefits of the Smart Grid include increased reliability, more efficient use of electricity, better economics and increased resilience. The Smart Grid concept began to emerge in the early 2000s. Since then, many countries have been striving for smart grids. Smart grids of local character are clusters that in case of failure of the common external system are able to work autonomously. Their creation entails improvement and replacement of power transforming equipment , switchgears, transmission lines, automated control systems, metering, communications.

The decision to allow foreign products to enter the South African market is made by ESCOM, the government's authorized representative.

The tightening torques of the critical assemblies were virtually unchanged. Having opened the device, we were convinced that the condition of the parts was as if the module had been produced yesterday. And in fact almost 3 years had passed since the moment of assembly, 15...
