Design and Installation of Medium Voltage Switchgear (Facts

Distribution Level of A MV SwitchgearStandards For The Design and Installation of MV SwitchgearMedium-Voltage Switchgear DesignIn analogy to distribution grids, switchgear can be assigned to the primary or secondary distribution level: Primary Distribution – What is characteristic for the primary distribution level are high load and short-circuit currents and high-end secondary featuresof the switchgear with regard to protection, measuring, and (remote) control. The switchgear is almost completely equipped with circuit-breakers. They switch large consumers, mostly in industrial plants, or cable rings which feed switchgear at the secondary distribution level. Secondary Distribution – At the secondary distribution level, the switchgear is equipped with switches or a mixture of switches and circuit-breakers, where the proportion of switches clearly dominates. The currents are lower, short-circuit protection is often ensured by the assigned circuit breaker at the primary distribution level. The requirements placed on secondary features are usually lower. Generally speaking, typical forms of substation are:Get price
