• Self powered: Powered by lithium batteries
• It can measure the transformation ratio polarity of PT and the transformation ratio group of transformer. It can measure the polarity/group of single-phase and three-phase, and complete the measurement of AB, BC, CA three-phase transformation ratio, group, error, tapping position, tapping value and other parameters in one go. It can automatically identify the group number.
• At the same time, it has two functions: turn ratio measurement and operating voltage ratio measurement. The operating ratio can more accurately reflect the actual value of the voltage ratio of the transformer and PT in actual operation.
• The test source used in this instrument is a standard sine digital source that is digitally synthesized, with a distortion of less than 0.1% and is not affected by mains power.
• Adopting a 3.5-inch high-definition true color LCD screen, the display data effect and vector image effect are intuitive and delicate.
