Living maintenance considers equipment obsolescence. Replacing aging, failing equipment becomes necessity once parts aren't available. Each replacement with new technology requires scheduled maintenance adjustments to capture benefits. Failure to readjust inspection intervals replacing 4kV air blast with vacuum breakers, for example, forgoes the opportunity to extend inspection intervals. For vacuum breakers, that would be from two to ten years! For a typical generating plant with 200 4 kV medium voltage breakers, scheduled work drops from 4 hours to twenty minutes (4 - to - 0.33 hours) per breaker. Annual PM Work drops by 193 hours! Living maintenance plans should capture technology improvements to reduce operating costs.
