MAINTENANCE PROCEDURES
Proper maintenance of electrical systems helps in minimizing/preventing unwarranted breakdowns of Equipment / lines improving the reliability and generating revenue. Periodical or preventive maintenance is normally followed to keep the equipment continuously in service for desired output.
Condition based maintenance is the most accepted and adopted concept in maintenance now a day’s which helps in providing advance information about the health of the equipment to take corrective action in advance.
As the system is growing, it is getting more and more complex. Due to stringent regulations the utility cannot afford to have breakdowns in the system resulting in interruption of power supply to the consumer. On the other hand equipment are getting older and are more prone to failure.
Equipment overhaul and major maintenance are also expensive and need to be planned based on the condition of the equipment rather than on a periodic basis as a routine.
