Product Introduction:
A Primary Current Injector Test Set is a specialized electrical testing equipment that can generate currents of up to thousands or even tens of thousands of amperes. It is commonly referred to as a "current booster" or "current source", and its core function is to simulate and provide high currents far beyond what ordinary power sources can provide.
It is an indispensable safety testing equipment in the power system, electrical manufacturing industry, and scientific research institutions. It simulates extreme current conditions to ensure the safe and reliable operation of power equipment, especially in the event of a short circuit fault, and is an important line of defense to ensure the safety of the power grid and equipment.

Core functions and technical features of the product
1. Adopting a low voltage input and high current output design, the overall structure is compact and easy to move and deploy on site. The equipment is equipped with high-quality voltage regulators and current boosters, and through reasonable electromagnetic design and material selection, strives to output stable current within the rated range. The operation interface of its current regulation system is simple and intuitive, and the output current can be smoothly controlled by rotating the handle, making it convenient for operators to adjust accurately.
2. The device has safety functions such as overcurrent protection and timing alarm. When the output current exceeds the set limit or the testing time reaches the preset duration, the device can automatically trigger the corresponding action, providing basic guarantee for the testing process. The clear display of instruments and meters can reflect the working status in real time, which helps testers to grasp the operation of the equipment.
3. In terms of structural design, the equipment adopts two schemes: split type or integrated type, and users can flexibly choose according to the on-site space and testing requirements. The wiring terminal layout is reasonable and equipped with clear markings, reducing the complexity of on-site wiring. For testing scenarios with long-term continuous operation, the cooling structure of the equipment has been specially optimized to help maintain the core components operating at suitable temperatures.

Case study
Case 1: Batch Calibration of Transformers by Provincial Electric Power Research Institute. A provincial electric power research institute is responsible for the periodic calibration of a large number of current transformers in its jurisdiction. They need a high current generator with a wide output range, high adjustment fineness, low operating noise, and the ability to work stably for a long time. After adopting the corresponding model equipment of Wuhan UHV, the test personnel provided feedback that the current regulation of the equipment was stable and the output value was accurate. In the batch calibration for several consecutive days, the equipment operated stably and the data display consistency was good, significantly improving the efficiency and reliability of the calibration work. Its intelligent control unit has preset parameters and recording functions, which also simplifies the repetitive testing process.
Case 2: Temperature Rise and Characteristics Test of Circuit Breaker Manufacturing Enterprise A large circuit breaker manufacturing enterprise needs to conduct temperature rise test and short-time withstand current capability test on the circuit breaker before the product leaves the factory. This type of test requires the current generator to be able to simulate the electrical stress that the circuit breaker is subjected to under abnormal operating conditions, and the output must be sufficiently stable to ensure the effectiveness of the test. The enterprise has chosen Wuhan UHV high current generator for production line testing. The application shows that the device can provide high current that meets the test requirements and maintain stable output during the testing process. The timing alarm and overcurrent protection functions of the equipment make the testing process more controllable and safe. Its compact or modular design also adapts to the spatial layout and mobility needs within the workshop.
