One charge enables continuous measurement of dozens to hundreds of units



The transformer capacity characteristic tester comes with a high-efficiency rechargeable battery, allowing operation without an external power supply. One charge enables continuous measurement of dozens to hundreds of units. Meanwhile, the internal digital synthesis of three-phase standard sine wave signals (by no means a simple inverter AC output, ensuring the accuracy of test data under non-rated conditions) provides a three-phase precision AC test source through a power amplifier. When measuring transformer capacity and short-circuit losses, there is no need for external three-phase test power supplies, voltage regulators, current boosters, or other auxiliary equipment, simplifying wiring and greatly improving work efficiency. The capacity test result accuracy rate reaches 100%. This device is equivalent to two devices: an active transformer capacity tester plus 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 simple and easy operation. It can completely replace the previous multi-meter method for measuring transformer losses and capacity, with simple wiring, convenient testing and recording, greatly improving work efficiency. The transformer capacity characteristic tester uses a large-screen graphic LCD as the display window, with graphic menu operation and Chinese character prompts, integrating multiple parameters on one screen. The human-machine interface is friendly, and the operation is simple and fast, making it the preferred product for power users at all levels.
