Introduction to the Features of the Transformer Volt-Ampere Characteristic Tester
发布时间：2022-08-18
The design methodology for a research and analysis testing instrument used in transformer management—also known as an instrument for testing the volt‑ampere characteristics of current and potential transformers, a volt‑ampere curve tester, or a device for evaluating transformer performance—is capable of conducting volt‑ampere characteristic tests on transformers by processing data at various voltage levels. It can also serve as a CT characteristic tester, a PT characteristic tester, and more. The comprehensive transformer characteristic tester is specifically designed for relay protection professionals to perform volt‑ampere characteristic measurements, turns‑ratio tests, and polarity identification on current transformers; it may also be employed for polarity‑determination tests on transformers.
The transformer volt-ampere characteristic tester employs low‑power, high‑quality materials and a specialized winding configuration. All testing can be performed by a single operator. With its lightweight design, user‑friendly operation, and distinctive performance, it is a rare instrument in the field.
Features of the Transformer Volt-Ampere Characteristic Tester
1. Operates on a single 220V AC power supply, ensuring safer use and providing reliable operation (completely eliminating the need to connect to hazardous 380V live lines).
2. Single-channel output: 2500 V / 1000 A;
3. Can be used as a 5A/5A–25,000A/5A or 5A/1A–5,000A/1A transformer;
4. Simply configure the test parameters for voltage and current analysis, and the device will automatically and rapidly complete the system‑level testing—no training required, making it easy for students to learn and master.
5. High single-unit output, comprehensive functionality, high precision, and distinctive performance;
6. 320×240 extra-large network LCD display screen, with a fully Chinese graphical user interface;
7. Equipped with an imported rotary mouse, enabling faster and more convenient setting of test values.
8. During testing, the volt-ampere curve can be displayed directly, with a clear, intuitive, and convenient graphical presentation.
9. Equipped with a built-in high-speed printer, enabling on-site printing of test and analysis results.
10. Equipped with a large-capacity memory, it can store 1,000 sets of test data without loss even after power failure, and the data is accessible at any time.
USB communication interface, easy to connect to new laptops, allowing test data to be uploaded for editing, saving, or printing.
12. Integrates multiple metering functions, enabling versatile multi‑purpose operation; continuously enhances the efficiency of student management accounting personnel while reducing the labor intensity for enterprises.
13. Supports both offline and online detection.
Features of the Transformer Volt-Ampere Characteristic Tester
1. The instrument is safe and easy to operate, featuring a fully computerized design with a built-in high-performance imported CPU, ensuring high reliability. After setting the test parameters as prompted by the interface, there is no need to manually touch the device under test; the instrument completes the test automatically. Test personnel can remain at a safe distance from high-voltage circuits, thereby safeguarding their personal safety.
2. Large output capacity: the maximum output voltage can reach 1000 V, the maximum current can reach 600 A, and the output data capacity is 5 kVA.
3. Optional accessories include an external booster, an external booster with an external regulator, and an external AC voltage stabilizer. When connected to any of these devices, the booster can increase the output voltage up to 2000 V at 3 A; the external device can deliver up to 1000 A through the booster; and the external AC voltage stabilizer can provide a maximum output current of 1000 A, with a maximum output voltage of 1500 V at 20 A. When using the external booster, it is possible to test the volt‑ampere characteristics of current transformers rated at 500 kV and 1 A.
4. A large-screen, 320×240 dot-matrix user interface for learning Chinese characters and managing graphical displays; after the test system completes its operation, it can directly show the I‑V characteristic curve, presenting the graph in a clearer, more aesthetically pleasing manner that facilitates students’ analytical skills development.
The instrument can use a rotary mouse as an input device, offering simple and convenient operation with a long service life.
