I. General Information
GDKC-5000 Transformer on-load tap changer tester is designed by general technical condition DL/T846, 8-2004 according to the national power industry standard high voltage test equipment, which can meet the requirement of checking the action sequence of on-load tap changer and measuring the switch time inPower equipment and preventive testing procedures. It is an ideal equipment to achieve the precise paramenter measurement of transition time, transition waveform, transition resistance, the same period of the three-phase for on-load tap changer.
II. Features
L Measure Y0, Y, type transforer, directly display resistance value without conversion.
L Humane data analysis and automatically identify the fault of waveform and mark it.
L Waveform displays the automatically adjusted resistance value and magnitude of the time according to the sampling data
L type transforer can display the same period of three phase.
L Can test with or without winding
L Four-terminal wiring way, providing high precise resistance measurements and without compensation wire
L Can continuously test to save the transformer outage time during testing.
L Instrument can generate word report to make data management and query easier.
L Instrument is control by small computer with 800 x480 color LCD touch screen, high-speed printer and can support plug-in mouse, easily operate.
L Automatically save 1000 sets of data and save with external U disk.
