| Abstract: | The hardware of the new multifunctional on-line measuring system, model ZJ-01, is introduced in this paper. The hardware, composed of a multicircuit switch and a digital acquisition device, has great advantage in performance parameters because of the best design. The functions of the hardware arc, in turn, selecting the analog signals coming from sensors, converting the analog singals to digital signals and sending the digital signals to a microcomputer to calculate and analyze. The hardware provides guarantees for the system to measure insulation parameters and electric power parameters. |
