Preventive Maintenance Test
with Insulation Resistance Test
Preventive maintenance is a predetermined task performed based on a schedule and its objective is to
keep equipment in good condition to avoid breakdowns.
Insulation resistance testing is commonly performed as part of electrical testing in a preventive
maintenance program for rotating machines, cables, switches, transformers, and electrical machinery
where insulating integrity is needed. Insulation resistance testing in the preventive maintenance pro-
gram helps identify potential electrical issues to reduce unpredictable, premature equipment repairs
and replacement costs.
With properly scheduled monitoring and data collection, this testing can be very useful in analyzing
and predicting the current and future behavior of equipment. Early problem detection helps avoid
major repairs, resulti|
