What are the functions and features of a transformer volt-ampere characteristic tester?
发布时间：2022-03-17
The transformer volt-ampere characteristic tester is also known as a transformer tester, a comprehensive volt-ampere characteristic tester, a transformer characteristic tester, a current‑voltage transformer tester, a CT characteristic tester, a PT characteristic tester, or a comprehensive transformer tester, among other names.
The instrument for testing the volt-ampere characteristics of current and voltage transformers is specifically designed for relay protection applications, enabling tests of the volt-ampere characteristics, turns-ratio, and polarity of current transformers. It can also be used to determine transformer polarity, making it a high‑performance, cost‑effective, multi‑function testing device.
The transformer volt‑ampere characteristic tester employs a high‑efficiency, low‑consumption, premium‑grade booster with a specially wound coil. A microcontroller handles data acquisition, analysis, and storage, while a built-in miniature printer enables printing of test results and curves. When measuring CT turns ratios, it automatically calculates the ratio value. All testing can be performed by a single operator. With its lightweight design, user‑friendly operation, and distinctive performance, this instrument is an invaluable tool for field personnel. The integrated transformer tester, equipped with a high‑power internal power supply, supports continuous operation during volt‑ampere characteristic and power tests.
The functions and features of the transformer volt‑ampere characteristic tester have been described above. In practice, additional functionalities and characteristics will become apparent during use; users may also conduct operational tests based on guidance from technical personnel or by referring to the instrument’s user manual.
