Leading pan-African telecoms group Liquid Telecom will implement and operate South Sudan's first fibre broadband network, connecting the country to the “One Africa” broadband network, which is approaching 70,000km across 13 African countries and to the rest of the world. First phase of the project completed in January 2020 includes a 200km fibre backbone.
[pdf] Use this Protection Relay Setting Calculator to calculate pickup current, time multiplier settings (TMS), operating time, coordination time interval (CTI), and plug setting multiplier (PSM) using fault current, CT ratio, and IEC 60255 curve parameters. The selected protection principle affects the operating speed of the protection, which has a significant im-pact on the harm caused by short circuits. At the beginn ng of the article it is drawn up process to protect power lines. Consequently, it is shown the method of calculation for a particular power line a d performed the calculation for setting the distance protection. dk is Denmark's transmission system oper-ator.
