On_line Measurement System of Virtual Dielectric Loss Based on Wavelets and LabVIEW and Correlation Technics

摘要

This paper presents the principles and instrument structures of on_line measurement system for dielectric loss of virtual capacitive_type equipment. The system based on wavelets, LabVIEW, GPRS network and SPC correlation technics, which can efficiently solve the problem of eliminating noises from signals, removing the electromagnetism interference to measure the results of influence, global area and full auto on_line measurement, to attain the higher precision of measurement.
