NOTES
1. Average velocity through the arc zone is calculated by using the following formula:
V
ave
= 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, use the CT-6500 the PC software.
