Product Details


■ Product Overview

The transformer capacity characteristic tester integrates the functions of both an active transformer capacity tester and a transformer loss parameter tester. , It can accurately measure power-frequency parameters such as the capacity, load loss, no-load loss, impedance voltage, and no-load current of various transformers. This instrument is equipped with a high-capacity rechargeable lithium battery. , When measuring transformer capacity and load losses, no external three-phase test power supply, voltage regulator, current booster, or other auxiliary equipment is required; a single charge enables continuous measurements. 100 Number of sessions ; Meanwhile, an internally digitally synthesized three-phase standard sinusoidal signal is generated. , The power amplifier can provide a three-phase precision AC test source, with test accuracy reaching 100%

■Product Features

It can passively and accurately measure the capacity of various distribution transformers.

It can automatically perform waveform distortion correction, temperature correction, and voltage correction. ( No-load test under non-rated voltage conditions ) , current correction ( Short-circuit test under non-rated current conditions ), Operators need only enter the correction factor corresponding to the transformer type, and the instrument will automatically compute the corrected results, making it ideally suited for facilities that lack the resources to conduct short-circuit tests on larger‑capacity transformers. External voltage and current transformers can be connected to extend the measurement range, enabling the testing of devices across a wide variety of parameters.

Wide-range voltage circuit : Accuracy is maintained without the need to switch ranges, and the instrument will not be damaged even if the voltage range is selected incorrectly.

A full-touch, industrial-grade, large color LCD screen that remains clearly visible in sunlight.

Users can print test results at any time using the miniature printer.
