Description
Summary:A method of calculation of electromagnetic transients in a multiconductor transmission system using the superposition principle and Hartley transform is developed. The method takes into account all frequency dependent parameters of the transmission system. In the method, the impulse responses of a transmission system are first obtained in the actual phase domain using a Hartley transform method. Then, the impulse responses are included in a transient calculation using the superposition principle. The properties and advantages of the Hartley transform are considered in comparison with more usual approaches using the other transform methods. The new method is applied on different transmission systems (underground power cables and power overhead lines). The results are compared with those calculated by using conventional methods and field tests. The accuracy of the method is found to be good.< >
