√ transformer on load tap changer parameter comprehensive tester is a special instrument used to measure and analyze the action characteristics of transformer on load tap changer. It can test the transition process, transition waveform, transition time, transition resistance value, three-phase synchronization and other parameters of the on load tap changer.
√ The instrument is highly intelligent. After the test is completed, the transition resistance, transition time and other parameters are automatically displayed.
√ Color large screen display, waveform and data display more clearly.
√ It can be tested with or without winding.
√ Chinese menu prompt is clear and easy to operate.
√ The test results can be stored and printed. The instrument itself can store 1000 groups of data, and the data will not be lost after power failure.
√ Adjustable permanent clock, no need to input date and time during test.
√ Anti interference, wide working supply source range.
√ Compact designation, suitable for wild filed testing.
