Number
Description
1 Test record number and the date and time the test was performed.
2 Test record header information (Company, Station, Circuit, etc.).
3 Type of test performed (OPEN, CLOSE, O-C, C-O, or O-C-O).
4 Contact channel times shown in milliseconds and cycles.
5 Contact channel bounce times shown in milliseconds.
6 Contact channel wipe distances in inches.
7
Contact delta time in milliseconds. This is the difference between the slowest contact time and the
fastest contact time.
8
Current transformer time in milliseconds and cycles. This is the circuit breaker open or close time when
using the CT-8000 AC current sensor for on-line testing.
9 Breaker contact stroke in inches.
10 Contact velocity in feet per second.
11 Contact over-travel distance in inches.
12 Contact bounce-back distance in inches.
13 Contact velocity calculation points.
14 DC power supply nominal and minimum voltage (if DC power supply was monitored during testing).
15 Initiate current.
16 Timing shot duration.
17 Insertion time (if breaker had an insertion resistor) or “NO” if there was no resistor.
18 Trigger mode (Internal or External)
