REACTIVE MAINTENANCE

also referred to as breakdown maintenance,

is the most common form of equipment

maintenance practiced in the industry today.

PREVENTIVE MAINTENANCE

Is a program of routine equipment

inspections, maintenance task and repairs

which are scheduled to ensure that

degradation of equipment is minimized.

PREDICTIVE MAINTENANCE

Is the technique of regularly monitoring

selected parameters of equipment operation

to detect and correct a potential problem

before it causes a failure

Why Maintenance Is So Important?

A maintenance program ensures continuity of

operation and lessens the danger of unplanned

outages. Planned shutdowns take place during

periods of inactivity or least usage, and as a

result, troubles can be detected in the early stages

and corrective action taken before extensive

damage is done.

Causes Of Electrical Failure

Dust And Dirt Accumulation

Presence of Moisture

Loose Connection

Friction
