How to Use a Transformer Volt-Ampere Characteristic Tester!

发布时间：2022-05-10

The transformer volt‑ampere characteristic tester employs a high‑efficiency, low‑consumption, premium‑grade booster with a specially wound coil. A microprocessor handles data acquisition, analysis, and storage, while a built-in miniature printer enables printing of test results and curves. When measuring CT turns ratios, the device automatically calculates the ratio value. All testing can be performed by a single operator. The instrument is lightweight, easy to carry, and simple to operate, offering distinctive performance.

Precautions for using the transformer volt‑ampere characteristic tester: The secondary winding of a current transformer must not have a grounding point. Wiring and disconnecting may be performed only when the voltage regulator switch and the output switch are in the open position. Prior to testing, this equipment must be reliably grounded. After completing the test, promptly return the device to the zero position, and never allow it to remain at high voltage or large current for extended periods.

The output power of the V‑A characteristic tester is expressed in actual voltage and current values, with a standard sinusoidal waveform at a frequency of 50–60 Hz. It can effectively simulate the transformer’s real‑world operating conditions, thereby meeting the requirements of relevant national maintenance procedures.
