Development of Automatic Data Acquisition & Remote Diagnostic System for Improving Efficiency of High-Voltage Motors Off-Line Insulation Diagnostic Test

고압전동기 Off-Line 절연진단시험 효율개선을 위한 데이터자동취득 및 원격진단시스템 구축

This paper proposes a method for improving efficiency of high-voltage motors off-line insulation diagnostic test. The conventional manual test method has measurement errors and excessive processing time. We developed the KITAS system and solved these problems by using the instrument remote control and communication technology. The result of proficiency testing by interlaboratory comparisons using Power Factor Tip-Up test was '${\mid}E_n{\mid}$ < 1'. It was possible to confirm the validity of acquired data from the KITAS and establish a remote diagnostic system for easy access without physical limitations.
