9.7 Maintenance-Related Design Study.

9.7.1

A maintenance-related design study uses the risk assessment study as input and evaluates design concepts for electrical equipment and installations that impact the safety of maintenance practices. The objective is to develop design options that eliminate or reduce hazards or reduce risk. Facilities management can use this study to assist in making decisions on implementing changes to the electrical equipment.

9.7.2

After the risk assessment study in Section 9.6 is completed, a maintenance-related design study should be performed.

11.4 Frequency of Tests.

Most routine testing can best be performed concurrently with routine preventive maintenance, because a single outage will serve to allow both procedures. For that reason, the frequency of testing generally coincides with the frequency of maintenance. The optimum cycle depends on the use to which the equipment is put and the operating and environmental conditions of the equipment.many factors such as equipment design, condition, use, age, loading, and duty cycle as well as prior recorded maintenance data, environmental factors, and reliability requirements. In general, this cycle can range from 6 months to 3 years, depending on conditions and equipment use.from 3 months to 6 years. The difficulty of obtaining an outage should never be a factor in determining the frequency of testing and maintenance. Equipment for which an outage is difficult to obtain is usually the equipment that is most vital in the operation of the electrical system. Consequently, a failure of this equipment would most likely create the most problems relative to the continued successful operation of the system. In addition to routine testing, tests should be performed any time equipment has been subjected to conditions that possibly could have caused it to be unable to continue to perform its design function properly. Annex L provides an initial guideline for equipment maintenance intervals. See Section L.1.

L.1 Introduction.

This annex provides, in Table L.1, an initial guideline for maintenance intervals for equipment. It should be stressed that environmental or operating conditions of a specific installation should be considered and might dictate a different frequency of maintenance than suggested in this annex (see 8.2.4). Chapter 12 and Annex K deal specifically with the maintenance of equipment that, by nature of its application, necessitates long intervals between shutdowns. It should be noted that maintenance, inspection, and test methods for equipment that can operate for long periods are essentially the same as for equipment that might be shut down frequently. However, the recommended work should be performed with more care and diligence to obtain the desired reliability for service to loads that can operate continuously for months or years.
