HMSLQ-3000A Primary Current Injection Test Display Video
Products Description
In daily operations, it is necessary to verify through high-current simulation testing whether equipment such as switchgear, bus ducts, circuit breakers, isolating switches, and cable joints will overheat when energized for extended periods and whether they can withstand the rated current. Additionally, the turns ratio, polarity, and load capacity of current transformers, as well as the operating sensitivity of various overcurrent relays and protective devices, can all be tested using 3,000 A high-current testing equipment.
Given the strong electromagnetic interference in substations and the complex conditions at construction sites, this 3000A current booster has been optimized for interference resistance, ensuring stable test data without drift and consistent results between on-site measurements and laboratory testing. Whether used by equipment manufacturers for batch factory testing or by power supply companies and third-party testing agencies for preventive testing and handover acceptance, it is fully capable of meeting these needs and is suitable for the vast majority of conventional high-current testing scenarios.
Main Functions
1)Adopts PLC (Programmable Logic Controller) as the core processor to scan AC signals in real‑time, realizing comprehensive monitoring and closed‑loop control.
2)Equipped with a 15‑inch true‑color large LCD touch screen. Intelligent sensors supporting field‑bus technology enable fully‑digital data transmission. The display‑operation unit adopts a touch‑type color LCD screen with full‑Chinese menus, delivering a clear, intuitive and user‑friendly interface. No external auxiliary equipment is required for tests, thanks to fully‑automatic control for easy operation.
3)This instrument supports fully‑automatic test function. Simply set the test current and duration, and its automatic current‑stabilizing system will take over the work.
4)Once the test current is set, manual supervision is not required. It eliminates tedious work including manual voltage regulation, manual data recording and curve plotting, which reduces labor intensity and improves working efficiency.
5)Reliable protection functions against over‑temperature, over‑current and over‑voltage.
6)Human‑oriented and user‑friendly software interface with full‑Chinese operation menus. During the test, it automatically tracks the target current, stabilizes output current and adjusts three‑phase current. After test completion, the output will automatically return to zero position.
7)Built‑in three‑phase automatic balancing system ensures balanced three‑phase output. High‑accuracy current transformers are applied for output current sampling. Adopting the latest power electronic technologies, the unit features strong anti‑interference performance and high output accuracy up to class 0.2.
8)Comes with waveform detection function for power‑quality analysis.
