ELECTRICAL PREVENTIVE MAINTENANCE
Too many people mistakenly think a lack of moving parts means little can go wrong
with electrical systems. The failure rate of electrical components is three times
higher for systems without preventive maintenance programmes.
The two top causes of electrical distribution failures, loose connections and exposure
to moisture, account for nearly half of all electrical losses. Both problems can
be corrected with a comprehensive electrical preventive maintenance (EPM) programme.
Consideration should be given to the following factors when planning a maintenance
The people who perform your EPM programme must be properly trained for the specific
equipment being maintained or tested. They should have a thorough understanding
of electrical safety practices and procedures.
Inspection,testing and servicing of equipment should be done on a regular basis,
at least once every three years and more often for critical components.
It will be necessary to make informed, responsible decisions about how best to correct
any problem conditions. This can only be accomplished if personnel reviewing test
reports have a thorough understanding.
Performing the Work
There is little point in testing and inspections if there is no intention to fix
the problem. It is preferable to take the plant out of service at a time most suited
to business needs.
A clear, concise and complete record-keeping system will help make sure that all
work is done when it should be. Tracking test results over time also can often identify
a potential failure that can be corrected before it happens.
Electrical preventive maintenance is cost-effective as it improves equipment efficiency
and reduces utility bills. The electrical distribution system should not be neglected.
An EPM programme should be considered before a costly failure occurs.
Inspection of complete electrical installations is available from
HSB Engineering Insurance, we can also limit inspections to specified items.
