Electrical transformer measuring device Portable tester for empty load and no-load
-The device features a built-in ARM processor with a main frequency of approximately 168 MHz, 128 MB of RAM, and expandable storage up to 4 GB. It is equipped with a 7-inch high-definition color touchscreen (some models have an 8-inch version) and the user-friendly emWin graphical interface, allowing for keyboard-free touch operation.
-It integrates a rich set of functions, including recording no-load test curves, harmonic analysis (supporting measurement of harmonic components 1–32 and providing waveforms/bar graphs), vector graph display, and presentation of voltage, current, and power parameters. Test data can also be exported and read via USB flash drives and a computer.
-The device's small size, light weight, and compact structure make it easy to carry and use for field measurements. With its precise measurement capabilities, database storage, USB flash drive export, and on-site printing, it is widely applicable for transformer fault analysis and performance evaluation.
