Popis: | In order to understand overvoltage phenomena due to the lightning surge in a low voltage wiring on a scale model of a structure, the load circuit of electrical appliances at the end of cable with circuit elements, such as resistors, capacitors and inductors, was simulated and the response at the end of cable was studied. Furthermore experimental results were compared with those of the digital simulation using EMTP (Electro-Magnetic Transients Program). The variation in the voltage waveform generated at the end of cable according to the state of the load of an electrical equipment was confirmed based on experiments and simulations. However, when a varistor (Surge Protective Device) was inserted at the end of cable, the voltage amplitude was clamped by the varistor irrespective of the load circuit. |
