Research On Detection System Of The Transformer OLTC

In this paper, the switch process and the detection principle of the OLTC is introduced. Based on this principle, the OLTC detection system is designed. The host computer software for the detecting system of the OLTC is introduced in this paper. The software is based on LabVIEW, and with the VISA technique, the serial transmission for the host computer and the guest computer is implemented. The LABVIEW data base toolkit can realize the interconnection of the VI and the ACCESS data base, and can manage amounts of history data. Calling the generating report toolkit of the LABVIEW can generate the test report of Word format. Finally, with this system, the detected kinds of typical faults of theOLTC are proposed.
