Supply GHKC-D transformer load switch tester

GHKC-D transformer load switch tester GHKC-D transformer load switch tester is used to measure and analyze power system of power transformers and special transformers on-load tap-electrical performance of the integrated measuring instrument. It is controlled by microcomputer circuit design through precision measurement can be realized on-load tap-tap of the transition period, the transition waveform, transition resistance, three-phase over the same period and other parameters measured accurately. Users may need and site conditions, directly from the tap-lead measurements, but also by the three-phase transformer casing and neutral-point connection measurements. Product Features 1, can be realized on-load tap-tap of the transition period, the transition waveform, transition resistance, three-phase over the same period and other parameters measured accurately. 2, large LCD, the display clear and intuitive. 3, for data analysis, storage, printing 4, an external SD card for easy export data.
