Research On Monitoring System Of High-voltage Environment Room Based On Virtual Instrument

For studying the insulative character of high voltage electrical equipment in complicated air environment, environment room is necessary test equipment. In this paper, virtual instrument technology is applied to monitoring system of high-voltage environment room, and with LabVIEW as software platform, using hardware equipment as sensor, signal conditioning module, DAQ card and corresponding software on the basis of the computer. Monitoring system of environment room for satisfying high-voltage experiment requirements and measurement system of capacitive equipment dielectric loss tangent are developed, which operate easy, applying flexibility and strong function. A practical measurement example is given to prove their availability. The work performed in this paper will be of some value for further research on the insulative character of high voltage electrical equipment in complicated air environment.
