Primary Current Test Set System

7000A Long time running primary current test set system

Primary Current Injection Test Set is a necessary equipment in various industries that require high current in electrical commissioning. It is used in power plants, transformer and distribution stations, electrical manufacturing plants and scientific research and laboratory units. It belongs to the short-term or intermittent working system. The HMSLQ Primary Current Injection Test Set produced by our company has the characteristics of stable performance and convenient use and easy maintenance.

This product accepts the split structure, it is made up of electric automatic console, inductive voltage regulator and Primary current generator. it connects with the tested object through the high current conduct wire which is through the primary current generator. Meanwhile, it measures, monitors and operates through the CT in the primary current generator and the current indicator, voltage indicator, different indicators and buttons of display screen in the console.
