This tool allows for a single curve to be displayed with the calculated trip time. Alongside the calculated trip time, engineer test results can be compared for phases L1, L2 and L3.
The resulting plot can be saved and used in engineer reports by clicking Download image.
The formula and curve constants used to determine the trip times are shown below:
Curve type | k | α |
---|---|---|
Standard inverse | 0.140 | 0.020 |
Very inverse | 13.5 | 1 |
Extremely inverse | 80 | 2 |
Long time inverse | 120 | 1 |
