Equipment Repair and Maintenance
Repairing & Maintenance
Maintenance support provides an important contribution to ensure the reliability of components and electrical installations throughout their entire life. The correct functionality, performance, and reliability are achieved by providing the necessary maintenance in conjunction with adequate design, construction,maintainability and installation quality, and by their proper usage it is currently being considered to standardize the maintenance process of electrical equipment on the international basis.
Maintenance recommendations are based on industry standards and experience in Reclamation facilities. However, equipment and situations vary greatly, and sound engineering and management judgment must be exercised when applying these recommendations. Other sources of information must be consulted (e.g. manufacturer recommendations, unusual operating conditions, personal experience with the equipment, etc.) in conjunction with these maintenance recommendations. The practice of maintaining equipment on a regular schedule based on elapsed time or meter readings. Equipment Repair and Maintenance To restore the equipment to its functioning state based on factory standard.
Maintenance activities fall into three general categories:
- Routine Maintenance – Activities that are conducted while equipment and systems are in service. These activities are predictable and can be scheduled and budgeted. Generally, these are the activities scheduled on a time-based or meter-based schedule derived from preventive or predictive maintenance strategies. Some examples are visual inspections, cleaning, functional tests, measurement of operating quantities, lubrication, oil tests, and governor maintenance.
- Maintenance Testing – Activities that involve using test equipment to assess condition in an offline state. These activities are predictable and can be scheduled and budgeted. They may be scheduled on a time or meter basis but may be planned to coincide with scheduled equipment outages. Since these activities are predictable, some offices consider them “routine maintenance” or “preventive maintenance.” Some examples are governor alignments and balanced and unbalanced gate testing.
- Diagnostic Testing – Activities that involve using test equipment to assess the condition of equipment after unusual events, such as equipment failure/ repair/replacement or when equipment deterioration is suspected. These activities are not predictable and cannot be scheduled because they are required after a forced outage. Each office must budget for these events. Some examples are governor troubleshooting, unit balancing, and vibration testing.

Safety During Maintenance
Performing maintenance on mechanical equipment can be hazardous. Electrical and mechanical energy can cause injury and death if not managed properly. All maintenance activity should be conducted in accordance with the Hazardous Energy Control Program and Reclamation Safety and Health Standards. A job hazard analysis must be conducted as well. Visitors, contractors, and others working under clearances must be trained and must follow all clearance procedures.

Though “maintenance” is a familiar word to most people, its meaning and interpretation can differ to people in different positions. Generally, people think of the maintenance man as that person in dirty overalls, carrying an oil can and wrenches, who is called upon to fix a damaged or a faulty system. In service and manufacturing industries, maintenance is regarded as shop-floor activities,such as tightening nuts and bolts, lubricating bearings, or repairing machine parts when they break. Is this really what maintenance engineering all about? Is it because of this gloomy image that most young engineering graduates decline to pick up maintenance engineering jobs
A popular definition of maintenance is: “A means to maintain and improve the quality of the elements involved in a production process, continuously and cost-effectively through detecting and controlling the deviations in the condition of a production process that is decided planning and managerial activities at both the enterprise and the national levels
