This paper has proposed a power quality monitoring system on the detection of power disturbance in\r\nreal-time by using an embedded system. It can be controlled and monitored by its function via Ethernet\r\nnetwork. This system has been developed to monitor and detect any disturbance signals in power lines.\r\nIf any phase in the power lines has disturbance, the monitoring system will store the fault data into the\r\nchosen memory card. This developed system can allow users to control and receive data from the\r\nremote hardware via Ethernet network by using UDP and TCP/IP protocol. To transfer the disturbance\r\nfile that has been stored in the memory card to PC, the embedded TFTP server is applied in this step.\r\nThere are some advantages of using the developed application software: it can control the power\r\nquality monitoring hardware which being installed at the remote sites; can display the detected fault\r\ndata in the waveform; and also can connect to the various number of the monitoring hardware.
