NOTES
1. Average velocity through the arc zone is calculated by using the following
formula:
V
avg
= Distance
÷
Time
2. The breaker contact velocity can be recalculated based upon the data stored
inside the memory after any new analysis points were selected. The user does not
need to operate the breaker again to acquire new contact velocity data after
changing the analysis points because the new velocity is then calculated from the
travel data stored in memory from the last operation.
3. For complex velocity calculations, the user can create a test plan using the CT-
6500 Breaker Analysis Software from a PC. The test plan then can be downloaded
to the CT-6500. The complex breaker velocity calculation can now be executed
easily by recalling the test plan before running the timing test.
