Prima Series

Primary Injection Set

Product successfully added to the Quote List

Prima Series is designed for Primary Current Injection Testing of Current Transformers, Protection Relays & Circuit Breakers during their Factory Test, Commissioning and Routine Testing. It is also used to test the Turns Ratio of Current Transformers and for other applications that require variable high currents. The Kit is designed for most optimal use of man and machine and is suitable to work in live switchyard conditions. Prima consists of a Control Unit and a low weight Loading Transformer, enabling the user to take the Loading Transformer nearest to the CT terminal. Thus, the weight of both the output lead and overall kit reduces considerably. The innovative design of Prima gives the ultimate flexibility to the user to use the full capacity of the Loading Transformer by adjusting the output voltage and current as per requirement.
