Fully type-tested The switchgear has undergone all the tests required by the international (IEC) Standards. Each switchgear unit is subjected to routine tests in the factory before delivery. These tests are intended to provide a functional check of the switchgear based on the specific characteristics of each installation. IEC type tests • Short-time and peak withstand current • Temperature rise • Internal arc capability • Dielectric test • Making and breaking capacity of circuit-breaker • Earthing switch making capacity (top application) • Mechanical operations of circuit-breaker and line disconnector • IP degree and impact test IEC routine factory tests • Visual inspection and check • Mechanical sequence operations • Cabling check • Electrical sequence operations • Power frequency withstand voltage • Measurement of the resistance of the main circuits • Secondary insulation test
