1. Accurately measures the capacity of various distribution transformers, conveniently and accurately.
2. Measures transformer no-load current, no-load loss, short-circuit voltage, and short-circuit (load) loss.
3. Automatically switches ranges internally, allowing for a wide range of voltage and current measurements, with simple wiring.
4. When performing no-load and load tests on three-phase transformers, the instrument automatically determines the correctness of the wiring and displays vector diagrams of three-phase voltage and current.
5. A single unit can perform load tests on distribution transformers up to 1000KVA under full current; it can also perform load tests on distribution transformers up to 3150KVA under one-third of the rated current (at one-third of the rated current, the instrument can convert to load loss parameters at the rated current).
6. All test results are automatically corrected. The instrument automatically performs various corrections such as waveform correction, temperature correction, non-rated voltage correction, and non-rated current correction, resulting in higher accuracy of test results.
7. A large 320x240 high-brightness LCD screen with a user-friendly interface featuring full Chinese character menus and operation prompts. Touch buttons simplify operation, and the wide-temperature LCD screen with brightness adjustment adapts to both winter and summer.
8. The instrument allows users to preset 40 sets of test sample parameters, which can be added or deleted as needed, making it very convenient to use.
9. A built-in real-time electronic clock automatically records the date and time of the test, facilitating the storage and management of experimental results.
10. A panel-mounted thermal printer allows for rapid on-site printing of test results.
11. Data (sample settings, measurement results, test time, etc.) has power-off storage and browsing functions, capable of storing 500 sets of experimental results and transmitting data online with a computer.
Extended measurement range can be achieved by connecting external voltage and current transformers, allowing measurement of test samples with arbitrary parameters.
