영문 초록

This paper is purposed to develop hardware and monitoring program to select NI-9215 of NI comp., which can be used in developing electrical equipment, to analyze and detect the 1∼1000㎃ and 1∼100A current signals. In this paper, The hardware which can interface with current sensors(CTL-24-S28-10Z and CTL-24-TE), is developed by NI-9215 of NI comp. The NI-9215 for use with NI USB chassis includes four simultaneously sampled analog input channels and successive approximation register(SAR) 16-bit analog-to-digital converters.(ADCs) The NI-9215 contains a channel-to-earth ground doubleisolation barrier for safety and noise immunity, and high common-mode voltage range. The monitoring program which can interface with NI-9215, is developed by SignalExpress of LabVIEW. The monitoring program are developed to analyze well at the same time on electrical signals such as RMS value, instantaneous value of current, THD, FFT signals etc, and to measure abnormal signals on the electrical wires. Verification experiment was conducted to evaluate usefulness and availability of the schemes in this paper.
