Demonstration case for practical application and training of VDE 0100 installation test equipment. The demonstration case simulates an electrical system, which is usually found in single-family houses or apartments. The demonstration case can be used to explain the basic operation of Benning test, measurement and safety devices, in particular VDE 0100 test devices. Different safety tests and measurements can be performed simulated on an electrical system. Acceptable or unacceptable parameters are preset by five fault switches. Some real elements of the electrical system are arranged on the front, e.g. RCD protective device, on/off switch with lamp, earthing contact socket-outlet and connection clamps. Other elements are shown improvised.This text is machine translated.
