Cost of Preventive Maintenance Program
Investment return of a preventive maintenance
cannot be measured
unless an unplanned or catastrophic outage occurs.
When such an
outage strikes, the value of a maintenance
program can be compared
directly to the cost of the outage.
However, one thing is certain, costs generated by a power
failure or
an unpredictable breakage are always higher than
the investment
required for a regular preventive maintenance
program.
