Key Features of the Product:

l Automatic Testing: This device simplifies the testing process with fast, easy, and convenient operation. It automatically calculates the inflection point voltage and current, as well as the compound error, and visually determines whether the transformer is qualified. It fully tests the volt-ampere characteristic curve, eliminating the need for manual pressure regulation, recording, and drawing curves. The user-friendly interface makes it easy to operate without special training.

l Comprehensive Functionality: The instrument can measure various parameters of protection CTs, including volt-ampere characteristics, 5% and 10% error curves, direct resistance, ratio, and polarity. It also supports qualitative measurement of voltage transformers by applying a power frequency voltage to the primary side, measuring the primary and secondary induced voltages, and determining the ratio and polarity. Additionally, it can measure the on-site secondary load of current and voltage transformers and evaluate the difference and angular difference of current transformers under load conditions.

l High-Resolution Graphic LCD with Full Chinese Interface: Featuring a large-screen graphic LCD, the device offers a clear, beautiful, and intuitive display. It directly shows the volt-ampere curve, and includes a built-in thermal printer for quick printing of graphs and test data. Users can also store test data at any time for future reference.

l Strong Expandability:

• a) External voltage regulator support: If the device’s output voltage and current are insufficient, an external voltage regulator can be connected easily for testing. The wiring and procedure are straightforward and user-friendly.
• b) Optional external booster: An optional external booster can provide up to 2000V and 3A, enabling the device to test the volt-ampere characteristics of high-class current transformers such as 5000/1.

l Data Storage and Printing: All test settings and data can be saved even after the device is powered off. This feature ensures that critical information is always accessible and provides a reliable record for future use.

This comprehensive transformer tester is ideal for engineers, technicians, and professionals who require accurate and efficient testing solutions in the field of electrical equipment and power systems.
