The impact of deferred maintenance on the average time to prune trees for line clearance as projected by the regression equation.
| Utility | Length of Optimum Line Clearance Cycle | Average Time (Worker Minutes) To Prune Trees At A Site That Is: | ||||
|---|---|---|---|---|---|---|
| At The Conductor* | 1-Yr. Past Optimum | 2 Yrs. Past Optimum | 3 Yrs. Past Optimum | 4 Yrs. Past Optimum | ||
| A | 5 Years | 68.9 | 84.9 | 98.7 | 109.6 | 116.2 |
| B | 5 Years | 56.9 | 68.8 | 79.2 | 87.1 | 93.2 |
| C | 6 Years | 43.4 | 50.5 | 56.3 | 60.8 | 64.0 |
↵* Optimum time is based on the industry standard of 10-15% maximum tree-to-conductor contact, referenced in this table as “At The Conductor”.
