Electric Vehicle Supply Equipment Electric vehicle supply equipment (EVSE) supplies electricity  to an electric vehicle (EV). Commonly called charging stations or charging docks, they provide electric power to the vehicle and use that to recharge the vehicle's batteries. EVSE systems include the electrical conductors, related equipment, software, and communications protocols that deliver energy efficiently and safely to the vehicle. Charging Equipment The function of the  charging equipment  is to transmit the burden materials through the locks in the furnace to desired locations on the burden surface in the throat. For many years, the two-bell charging system with movable armor was the only proper charging equipment but nowadays the bell-less rotating chute is dominating. The advantages of the bell-less top is the more accurate filling of the furnace and better gas tightness with higher top pressures. The stock level is measured either with a mechanical stock rod or with...

Commissioning Procedure After the installation of any PV system is completed and the inspection is done, the system will be ready to be plugged to the grid to transfer energy. That process is referred to as Commissioning the system. At the same time, the installer will hand the responsibilities to the owner or operator of the system. There are steps and requirements to commissioning PV systems that vary depending on system size and complexity of design. However, there are general guidelines that apply to most systems. Final checkout The system should be checked thoroughly before the commissioning starts. A highlight of the main electrical items to consider: All disconnects are in (OFF) position during the final checkout.? Installation matches the design documentation.? Conductors, OCPD, and disconnect are sized appropriately.? Compliance with all local AHJ and national codes (including NEC) is met.? Terminals connections and screws are securely tightened. ? A highlight of the main mech...
