Usage Features
The transformer capacity characteristic tester comes with a high-efficiency rechargeable battery, allowing operation without an external power supply. A single charge can support continuous measurements of dozens to hundreds of units. Internally, it generates three-phase standard sine wave signals digitally (not a simple inverter AC output, ensuring accurate test data under non-rated conditions). Through a power amplifier, it provides a three-phase precision AC test source. When measuring transformer capacity and short-circuit losses, no external three-phase test power supply, voltage regulator, or current booster is needed, simplifying wiring and greatly improving work efficiency. The accuracy of capacity test results reaches 100%. This device is equivalent to two devices: an active transformer capacity tester and a transformer loss parameter tester. It can precisely measure a series of power frequency parameters for various transformers, including capacity, no-load current, no-load loss, short-circuit loss, and impedance voltage. The transformer capacity characteristic tester features small size, light weight, high measurement accuracy, good stability, and easy operation, fully replacing previous multi-meter methods for measuring transformer losses and capacity. It simplifies wiring and facilitates testing and recording, greatly enhancing work efficiency. With a large-screen graphical LCD as the display window, graphical menu operation with Chinese prompts, and a multi-parameter single-screen display interface, it offers a user-friendly interface that is simple and quick to use, making it the preferred product for power users at all levels.
