Encompass CT vs. Standard CT
To demonstrate the advantages of upgrading to an Encompass CT,
let’s compare a JAK-0W 500:5 Encompass CT to a JAK-0C 200:5 standard CT
- Is lighter
- Has the exact same mounting plate
- Has the exact same terminal locations
- Has the exact same window size
- Physically, the JAK-0W 500:5 Encompass CT:
Electrically, the accuracy of a JAK-0W 500:5 is equivalent or better than the accuracy of a JAK-0C 200:5 across all test points. This can be looked at two ways:
A 500:5 Encompass CT has ±0.3% accuracy from 200A to 2000A, compared to a standard 200:5 CT which has a ±0.3% accuracy from 200A to only 800A. Both CT’s have ±0.6% accuracy from 20A to 200A.
The 500:5 Encompass CT has equal to or better accuracy rating across the entire 20A to 2000A range. It is important to note that accuracy class only defines the “tolerance of error” allowed in a CT. Actual test results are also an important factor when evaluating CT’s. At a typical burden of B-0.1, the Encompass CT test results slightly outperform a standard CT, even at the lowest test amps. All Encompass test results are well within the IEEE limits.

vary, within defined test tolerances.
