Powering the steel industry

Both metallurgical and other industrial plant processes, as well as large drive procedures depend on reliable, highly specialised transformers. In steel plants, for example, it is crucial to supply high currents for AC and DC electric as well as ladle furnaces. Electrolysis processes operate with heavy-duty rectifiers which are fed by rectifier transformers. Large drive […]

Commissioning and testing of differential protection for phase-shifting transformers

Due to the increasing demand to control power flow within our networks, more phase-shifting transformers (quadrature boosters) are being installed. The most important protection principle for transformers is differential protection. An additional phase-shift has to be considered by the differential protection to fulfill the requirements for selectivity. With two-phase faults outside of the transformer, an […]

Africa’s first ester transformer fluid factory opens

UK-based M&I Materials has opened a manufacturing facility in Ekurhuleni. The factory, which is the first of its kind in Africa, will produce the company’s Midel brand of fire-safe and biodegradable ester dielectric fluids for electricity transformers. Speaking at the official launch in Sandton, the company’s chief executive, Giles Salt, said that the factory, which […]
