A development on remote monitoring technology of distribution transformer using CDMA wireless data communication

This paper presents the operation technology and the remote monitoring system of distribution pole transformer. Especially, this system uses CDMA wireless data communication network as media which is serviced on a national scale. It has four major components such as sensor for measuring the secondary voltage and currents of distribution transformer, CDMA wireless modem for data modulating/demodulating, communication media for sending/receiving of data, and PC server for monitoring the results of sensing or computing information. This paper also describes the configuration of each component's functions with its development process.
