| Abstract: | An embedded measuring-control platform PC104 based microcomputer protective relaying tester is developed. The working principle of signal input and output units and the generation circuits for voltage source and current source are described. The modules of its hardware consist of signal output, digital outputs, switching value detection and supervisory circuit, and the software is running in master and slave computer respectively. The hardware and the software modules of the tester are presented in the viewpoint of product development, and finally the rated output of the tester and its measurement accuracy are given. The scheme of the tester can be used to test the required testing items of various present protective devices and its measuring accuracy is satisfactory. |
