The transformer capacity and no-load/load tester is a high-precision instrument specially developed and manufactured by our company for measuring transformer capacity and loss parameters. It comes with a high-efficiency rechargeable battery, allowing operation without an external power supply. A single charge can continuously measure up to 500 transformers. At the same time, the internal digital synthesis of three-phase standard sine wave signals (not 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 loss, 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 rate reaches 100%. This device is equivalent to four devices in one: a transformer capacity and no-load/load tester + a transformer loss parameter tester + a harmonic analyzer + an oscilloscope. 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 of various transformers. It can also measure voltage and current distortion rates and harmonic content during no-load and load tests, and perform vector analysis.
This instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and easy operation. It can completely replace the previous multi-meter method for measuring transformer loss and capacity. With simple wiring and convenient testing and recording, it greatly improves work efficiency. It uses a large-screen color LCD as the display window, with menu operation and Chinese prompts, integrating multiple parameters on one screen. The human-machine interface is friendly, making it simple and quick to use.
