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

The Basics of Personal Protective Grounding | ECM

PPGB EquipmentInstallation and Removal ProcedureMeps TechniquesAdditional RecommendationsSidebar: Hazards Associated with Temporary GroundingThis type of equipment is actually a system of connections, in that there are a number of points where the various components of the grounding cables must connect to the system to be grounded and to each other. It is vitally important to recognize that the grounding system is only as good as the weakest connection. In other words, having high-quality grounding cables but undersized grounding heads will render the system ineffective in protecting workers. There are a number of key concepts to remember when selecting PPGB equipment, including: Grounding heads — The grounding head is the only connection between the grounding system and the electrical circuit on which work is to be performed. Like grounding cables, the grounding heads must be rated to withstand the available fault current for the duration of the fault event. The data in the Tableidentifies the withstand ratings of one manufacturergrounding products. Grounding electrodes— The grounding electrodes are the other end of...Get price
