PDG-1 Electrical Testing In A Building Vocational Training Equipment Electrical Engineering Training Equipment
This panel can be used by teachers for their lessons and by students for an easy learning and testing on electrical prevention systems supplying them with the means for verifying the rule of art and the relevant technical standards. TRAINING PROGRAM: This panel can be used to define the electrical installations ofa building (power distribution via TT system) with reference tothe following topics: • Design documents complying with CEI standard 0-2;predesign, definite project • Electrical installation of the building complying with CEI guide64-50 2nd edition • Graphic symbols for installation plans • Branch exchange for a flat • Meter room and riser • Earthing system for the block of flats Furthermore, this panel is designed to deal with topics,visual checks, tests concerning: • Protection systems against direct and indirect contacts • Choice of conductors, current-carrying capacity and voltage drop • Testing the paths of conductors and their suitability and ductdiameter and removableness of conductors • Suitability of materials and of equipment • Protection and breaking devices • Identification of neutral and earth conductors • Suitability of the connections of conductors • Continuity of protection and equipotential conductors • Isolation resistance TECHNICAL SPECIFICATIONS: Framework is made of sheet steel chemically treated andpainted with several coats of epoxy varnish; its base is providedwith rubber feet and it can be positioned on a working top. All the necessary electric components for the correct powersupply of circuits are included in the panel.
