(a) Various required forms for use in the plant and in the field.
(b) A procedure for each piece of equipment; detailing the special tools, materials and
equipment necessary; an estimate of the time to perform the work, references to appropriate
technical manuals, record of previous work performed, items of special attention, precautions,
unusual incidents, etc.
(c) Safety procedures to be followed, special test equipment required, protective
equipment and barriers to be used, lockout/tagout/tryout procedure to be used.
(d) Implementation of actual plant inspection schedule, based on equipment scheduled
inspection frequencies, personnel availability, availability of spare equipment, shutdowns
permitted by operating personnel, anticipated time to perform inspections and tests, availability
of replacement parts and special test equipment.
(e) Maintenance of records to evaluate results (i.e., inspection schedules, work order
logs, unusual event logs, cost reports, and analysis of test results).
(f) Emergency procedures, including training in the emergency situations most likely to
occur, and periodic drills.
8.4 SYSTEM PLANNING STUDIES. This section discusses six system planning studies that
should be conducted periodically. Performed regularly, the studies provide an organized way to
track key system characteristics, such as, power factor, annual usage, peak demand, energy
losses, voltage and current profiles, and load factor. Tracking these characteristics helps the
system engineer to improve system performance, minimize downtime, and manage system
expansion. The studies should be performed simultaneously to ensure data consistency.
Each study is prepared on a load projection basis using an econometric forecasting method that
utilizes acquired electrical system historical data. The following studies will be discussed:
(a) Power Requirement Study.
(b) Long Range System Planning.
(c) Short Range System Planning.
(d) Coordination Study.
(e) Economic Conductor Analysis.
(f) Power Factor Correction.
8.4.1 Objectives. The objectives of these studies are to improve system performance and
reduce operating costs. The performance of the studies will provide information to ensure an
adequate supply of power and continuous service. Preparation of the studies is discussed in the
following paragraphs.
