Large Current Injection Test Set , Secondary Side Current Injection Test Set , Split Type , Short Time Working

I. Product Description

DDG series large current injection test set is a kind of heavy current generator , it is used in power plant,substation,electric appliances plant and scientific research,test room,etc. it works for short time or make by order, with of small volume,light weight,nice performance,easy for overhauling, The test set also called as heavy current generator , Secondary Current Injection Test Set , or Primary Current Injection Test Set.

The large current test set consists of a voltage regulating control box and a large current generator with large current test wire .It is mainly used for testing of MCCB ,ACB, bus-bar and various current transformers when need short time current injected. It is widely used in research, production and electrical test sites of power, railway, petrochemical, metallurgical and mining enterprises.The continuous output max time at rated current is usually 5mints on/more than 10mints off.

II. Applications:

• Current impact test For MCCB ,ACB, bus-bar and various CT
• The current calibration field for CT/PT  and other electrical equipments.
