Product Introduction:
Wuhan UHV Power Technology Co.,Ltd., is a professional manufacturer and supplier of high-voltage power testing equipment in China.The SL current generator is a high-current output device specifically designed for current transformer (CT) calibration and on-site testing in power systems. It can provide a stable and reliable primary test current for the CT under test, and can also be used as a 50Hz single-phase power source for other applications.
The device features a three-winding structure design, consisting of a 220V input winding, an output winding below 100A, and a through-core winding. Different current levels can be output through the through-core winding, meeting the application requirements of on-site CT calibration, laboratory testing, and power metering equipment verification.

Product Characteristics:
1. Three-winding structure design
Adopts a combination of input winding, output winding, and through-core winding, suitable for primary current output requirements in different testing scenarios, with reliable structure and flexible operation.
2. Flexible current output method
The rated output current is as specified on the nameplate. When the conductor passes through the core with multiple turns, the allowable rated current decreases accordingly as the number of through-core turns increases. The through-core turns can be flexibly configured based on actual test current requirements.
3. Supports overload operation
The device allows long-term operation at rated current, and also supports 1.5 times rated current overload operation for up to 30 minutes, meeting the requirements of some high-load testing scenarios.
4. Easy to move
The device is equipped with casters, facilitating movement and transport in laboratory, substation, and on-site testing environments, improving on-site usability.
5. Suitable for CT calibration
Can be used as a primary current source in current transformer calibration systems, providing a stable primary test current for CT ratio, error, and related testing.

Frequently Asked Questions
Q: What is the SL Current Generator mainly used for?
A: The SL Current Generator is mainly used as a high-current test source for current transformer (CT) testing and calibration. It can also be used as a 50Hz single-phase power source for other electrical testing applications.
Q: Can it be used for current transformer (CT) testing?
A: Yes. The SL Current Generator is designed to provide primary-side test current for CT testing, including applications such as CT ratio and error testing.
Q: How does the through-core winding work?
A: The test conductor can be passed through the core multiple times to obtain different current levels. As the number of turns increases, the allowable current decreases accordingly. This allows users to flexibly configure the test current according to their requirements.
Q: Can the generator operate continuously?
A: Yes. The unit can operate continuously at its rated current. It also supports operation at 1.5 times the rated current for up to 30 minutes, subject to the specified operating conditions.
