Three LabVIEW applications are developed. AMPA (Automated Measurements with Power Analyser) is software for measurements with PC-controlled PA (Power Analyser) through GPIB communication system. Measurements of three-phase transformer load losses, no-load losses, no-load current harmonics and zero impedance are automated. AMPA guides the operator, processes test data and guarantees customized test reports. ATRT (Automated Temperature-Rise Test) is software for automation of the most complex and time-consuming factory test of power transformers. ATRT integrates up to four digital multimeters, multichannel digital thermometer, PA and PC in the measuring system. ATRT guides, measures, displays, archives test data and creates final test reports. TRTR (Temperature-Rise Test Report creation) is program for easy creation of temperature-rise test reports made in the classical way, or with ATRT.
