Usage Features
The transformer capacity characteristic tester comes with a high-efficiency rechargeable battery, allowing it to operate without an external power source. A single charge can support continuous measurements of dozens to hundreds of units. Meanwhile, it internally synthesizes three-phase standard sine wave signals (not a simple inverter AC output, ensuring the accuracy of test data under non-rated conditions). Through a power amplifier, it can provide a three-phase precision AC test source. When measuring transformer capacity and short-circuit losses, there is no need for external three-phase test power supplies, voltage regulators, or current boosters, simplifying wiring and greatly improving work efficiency. The capacity test result accuracy 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 such as capacity, no-load current, no-load loss, short-circuit loss, and impedance voltage for various transformers. The transformer capacity characteristic tester has the advantages of small size, light weight, high measurement accuracy, good stability, and easy operation, fully replacing the previous multi-meter method for measuring transformer losses and capacity. It features simple wiring, convenient testing and recording, and greatly improves 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
