PDG-9 Installations For Medical Consulting Rooms And Surgeries Didactic Equipment Electrical Training Panel
This demonstration 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. Actual electrical devices installed, already connected with each other, enable to check the operation, besides carrying out the measurements of all the electric parameters with conventional instruments. TRAINING PROGRAM: This panel shows an electrical installation that can be foundin a building used as consulting room, with reference to thefollowing topics: • Rooms of group 0, 1, 2 • Patients’ area • Equipotential loop and branch point • Protection with automatic power cutoff • Protection by isolation transformer • Isolation resistance of walls and of floors • Protection by electric separation and SELV, PELV circuits • Measurement of first-fault current TECHNICAL SPECIFICATIONS: Framework is made of sheet steel chemically treated andpainted with several coats of epoxy varnish; its base isprovided with rubber feet. Main components installed: • 1 single-phase isolation transformer of 230 V / 230 V 230 VA • 1 switch for selecting TT, IT distribution system • 1 monitor for checking the isolation of IT system • 1 remote warning device for isolation monitor • 1 simulator of earth plate with resistances of 2 Ω, 20 Ω, 200 Ω, 2 kΩ • 3 simulations of extraneous conducting part with resistances of 200 Ω, 1000 Ω, 5000 Ω (pipes of water for radiator, metallic frame) • 1 magnetothermal circuit breaker 2 x 0.5 A “C” • 1 magnetothermal circuit breaker 2 x 1 A “C” • 1 differential circuit breaker 2 x 25 A / 30 mA “A”; two 2-pin sockets – 10/16 A, 2P + Earth • 2 simulators of isolation fault in a power consuming device (to earth) with resistances of 50 kΩ, 15 kΩ, 5 kΩ, 1500 Ω, 500 Ω and bolted fault Dimensions of demonstration panel: 800 x 600 mm Dimensions of framework: 840 x 450 x 680 mm Net weight: 35 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
