3 Protection against electrical shock in accordance to DIN VDE 0100 Part 410 Foreword Concept Learning contents / Experiments Our Training Systems program Protection Schemes to VDE 0100 is suitable to show the design, principle of operation and performance of the circuits protecting against indirect contact with the live parts specified in DIN VDE 0100 Part 410. The limits of the effectiveness of the individual protective measures are to be determined by measurements to ensure that the trainers understand the regulations specified. Protection schemes are continuos to be adapted to the newest technology, there fore we have enhanced our resp. training systems. For our experimental-panel system and the demonstration board we use commercially available test gear. VDE 0100 Training System is usable for testing protection schemes in electrical systems. By alternating the earth-resistors faults can be simulated and located. The results are useful to ensure the practical work of the trainees. Demonstration Board 230 V for teachers and instructors with practical oriented experiments for theoretical lessons Experimental-Panel System 230 V for the students to carry out several experiments to get familiarized with the different systems of protection schemes. The Complete Concept Decisive for this specified training system is the didactical structure of the complete training system. All circuits are printed with the same layout. Therefore the panels can be continued for the relevant experiments. The following learning contents are adapted to the professions in the field of electrical engineering and can be performed by using the demonstration board as well as the experimental panels. Introduction accident prevention regulations Guidelines for the performance of experiments Direct/indirect contact Protection against accidential contact with live parts Protection against electrical shock when touching exposed conduction parts Protection extra-low voltage / purpose extra-low voltage protection by means of extra-low voltage Exception of effectiveness functions of extra-low voltage Safety Separation Safety separation at a metal conductive location Safety separation with two loads Protection by Disconnection Tripping behaviour of circuit breakers Tripping behaviour of residualcurrent devices Protective measures in the TN- System Protection by disconnection with overcurrent protection devices in a TN-C-System Protection by disconnection with overcurrent protection devices and various PEN resistances restrictions on effectiveness Page 4 Catalog WA2E/08

4 Demonstration Board "Protection Schemes against electrical shock in accordance with DIN VDE 0100 Part 410 VDE-Demonstration Board 230V The VDE-Demostration board is built into a metal sheet cabinet with two lockable frontdoors, the frontpanel is white. The board can be set up on a bench. Scope of delivery including 1 Demo-board 230 V 1 Experimental manual W3006-3B 20 plug-connectors 4 mm 15 safety-connecting-leads 4 mm The concept of the VDE-demonstration board is according to the training regulations. To minimize the preparation for the experiments the design is a compact housing and includes all relevant components. To carry out all experiments we recommend two multimeters and one protectice schemes measuring unit. These instruments are not included the scope of supply. The components of the demonstration board are in accordance with the components used in the experimental panels system W2812-0A 650x900x250 mm 50 kg Order-No. W2812-1A Page 6 Catalog WA2E/08

5 Assembly kit with experimental panels Assembly kit "Protection schemes against excessive touch voltage to DIN VDE 0100 Part 410 Order-No. W2812-0A The assembly kit contains experimental panels and accessories, as well as the experimental manual. The panels are designed for insertion in the experimental frames. The layouts of the circuits are the same than on the demonstration board. of the panels (W x H) 297x130mm or wider by whole number multiples of 65mm The instruction modules permit various experiments to be carried out. We recommend that the assembly kit be used for carrying out the experiments in accordance with our instruction manual. The following components are required (included in the kit) System infeed with built-in 3-phase transformer for supplying the current, 3 miniature automatic circuit-breakers, phaselamps and in line resistors 390x297x190 mm 10 kg Order-No. W2812-2A Current-operated earthleakage circuit-breaker 4-pole 230/400V, 25A, ΔI n 30mA, with test potentiometer for fault simulation 195x297x110 mm 1,3 kg Order-No. W2812-2B Catalog WA2E/08 Page 7
