| Abstract: | A signal transmission system used for on line detecting partial discharge in electrical equipment has been develoned in this paper. The optical fiber system has been used for transmitting signal, because it can ensure safety of micro computer system and main control room and prevent the electric-magnetic inferferences.It applies transmission way of frequency-division multiplex and time-division multiplex to transmit multiple signals of partial discharge and control signals respectively. Then it can simplify the transmission system and reduce the cost. The design and fundamental of each part of optical fiber transmission system have been described in this paper. This system has been used for on-line detecting apparatus of partial discharge. And many tests of on line detecting partial discharge in electrical equipment have been finished successfully on field. |
