Transformation accuracy: 0.01% plus 0.001% of full scale

 

All JAMB Industries Amplifier Aided Transformers have a 1 ampere secondary.

 

Full Scale     Basic uncertainty        scale uncertainty          total uncertainty

0.1                  0.01                          x10          0.01                  0.02

0.02                 0.01                         x50          0.05                  0.06  

0.01                 0.01                         x100        0.1                    0.11

0.001               0.01                         x1000      1.0                    1.01

0.0001             0.01                         x10000   10.0                 10.01 

 

Example: Operating the CT5001 with a 100 ampere input will have a full scale 0.02 ampere secondary current. The uncertainty is 0.05 (50 x 0.001) yielding a total uncertainty of  0.06%.

 

The scale uncertainty is based on the noise floor measurement of 10exp-6 amperes (100% uncertainty). The scale uncertainty deceases linearly with an increasing secondary current range because the amplifier aided transformer operates at very low (linear) flux levels.
