Primary Current Injection Test System

The HMSLQ 5000A High Current Injection Test System is primarily employed for high current temperature rise testing of electrical equipment such as distribution boxes, busbars, and switches. The system supports customisable long-term operation modes and is equally suited for short-duration or intermittent work. As essential equipment for power stations, substations, distribution stations, electrical manufacturers, research institutions, and laboratories, it delivers stable and reliable performance with straightforward maintenance.
