OPERATING & MAINTENANCE PROCEDURES
General Recommendations
1.1 Introduction
Preventative Maintenance can be described as the routine inspection, testing and
cleaning, adjustments and early detection of incipient trouble likely to cause
breakdown. The efficient manner in which this is done can be assessed by freedom
from breakdown and behavior of plant under abnormal and fault conditions. Since
most of the equipment is normally static, attention is not always drawn to the
dangers which can result from general neglect and it follows that a properly
organised system of maintenance is essential.
Maintenance problems are influenced by site and atmospheric conditions, system
design and type of plant in use. The installation, testing and commissioning of
equipment is all-important and must be properly supervised. This section is confined
to the routine maintenance of existing plant and equipment and does not deal with
the more frequent inspections and test necessary during the commissioning period
and the immediate post-commissioning period.
Workshop plant, machinery testing equipment, vehicles and portable compressors
etc. have also been excluded
Statutory regulations must be observed by those engaged on maintenance.
1.2 Object
To ensure a satisfactory routine maintenance of distribution plant and equipment and
also to ensure a satisfactory method of reporting and recording maintenance.
1.3 Periodic Maintenance
The frequency of inspection and maintenance is given in the following sections but
intervals between inspections shown in these tables may be reduced at the discretion
of the Engineer, when plant is subject to severe or abnormal operating conditions to
where the record shows that more frequent maintenance is essential.
