8kVA Current Injection Unit: MODEL 4041

The Model 4041 is the largest of our switch mode current injection sources used for injection based testing.

This 3 phase unit works on the identical principle of operation

as our 2kVA system, however the 4041 in conjunction with

the 4042 coupling transformer have been specifically

designed to perform current injection tasks over very long

haul and demanding environments continuously at maximum

power.

With our 4025E or 4031 frequency selective multimeters,

terrestrial voltage profiling is made easy with GPS positional

information available on both the 4041 and 4025E/4031 units.

Another advantage of this is the ability for the two units to

synchronize phase readings, thus reducing the cabling

required when performing current split or branch

measurements and it also provides relative positioning

information so that the operator may choose the best line

of potential measurement during EPR tests to avoid

mutual coupling or induction.
