The transformer volt-ampere characteristic tester is a testing instrument specifically designed as a multifunctional field‑test device for evaluating current transformers. , used for Volt‑ampere characteristics, turns ratio, polarity, error curve, inflection point calculation, and secondary circuit verification. During the experiment, only the test voltage needs to be set. /With the current value set, the device can automatically increase voltage and current, quickly displaying the transformer’s volt‑ampere characteristic curve, ratio variation, polarity, and other test results, while supporting data storage and on-site printing. It not only eliminates the tedious tasks of manual voltage regulation, manual recording, and curve plotting, but also allows test data to be uploaded via the USB interface to a computer for editing, saving, or printing. The instrument for testing the volt‑ampere characteristics of current transformers is simple and convenient to operate, enhancing work efficiency, and represents a high‑performance, cost‑effective, cutting‑edge product.

The mutual inductor volt-ampere characteristic tester is commonly referred to as the transformer volt-ampere characteristic comprehensive tester, PT-V-A characteristic comprehensive tester, CT-V-A characteristic comprehensive tester, CT V-A characteristic tester, transformer V-A characteristic tester, V-A characteristic variation rate and polarity comprehensive tester, V-A characteristic comprehensive tester, CT-PT characteristic comprehensive tester.

Product Features of the Transformer Volt-Ampere Characteristic Tester: 1. 、 Safe and reliable. MBC power control technology is a domestic first: it uses a single-phase AC 220 V input, with the operating power and the power supply sharing a common input port, resulting in a more scientific and rational design that ensures safer, more reliable operation. Note: Other similar products feature separate inputs for operating power and power‑supply power, requiring a three‑phase AC 380 V dual‑wire input to meet experimental requirements. This approach poses significant safety risks, potentially leading to electric shock or even injury and fatalities. II 、 Complies with national maintenance regulations. The equipment’s power output is entirely based on true voltage and current values, and the waveform has a frequency of… A standard 50–60 Hz sinusoidal waveform; it can realistically and effectively simulate the actual operating conditions of a transformer, in compliance with relevant national maintenance regulations. Three 、 Large output capacity. Single-unit input. At 220 V, the device delivers a voltage output of 0–1000 V and a current output of 0–600 A, making it ideally suited for field maintenance. 4. Comprehensive functionality: It can test the volt‑ampere characteristics, transformation ratio, polarity, 5% and 10% error curves, as well as the primary current and demagnetization of current transformers, enabling versatile, multi‑purpose operation with ease. 5. 、 The wiring is straightforward, using a single power input port. ， Only six test ports can complete all of them. CT test project. This wiring method is safe and straightforward, making it highly suitable for field use; it effectively reduces labor intensity and enhances work efficiency.
