Primary & High Current Injection Testing

Primary current injection tests can be carried using our Programma Primary Current Injection Test Kits.

Picture
The ODEN AT can be used in a number of applications where high current is required the unit can produce several thousand amps of test current.  

Primary current injection testing of protective systems

Circuit Breaker testing

Testing current transformer

Heat runs
Example of test objects is joints, circuit breakers and disconnectors.

Testing of safety-ground devices

Personal safety grounds must be tested at rated current, a task for
 Which ODEN AT is well suited?

Testing integrity of ground grids

One way to make this test is by injecting current between a Reference ground and the ground to be tested and measuring the Voltage drop and the percentage of current flowing through the Earth grid.
