Primary Injection Kit (1)
Prima Series
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 tests the secondary current 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 switch yard conditions. Kit to be used for the injection of high current to the Primary side of the CT as per the guidelines of IEC 60044 / IEC 61869 and is suitable to work in live switch yard conditions up to 765kV.Prima consists of a separate Control Unit and Loading Transformer, it enables user to take the Loading Transformer nearest to the DUT’s terminal.
The weight of both the Output lead and overall kit reduces considerably. The kit has trolley / wheel mounted arrangement for easy transportation. 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.
