Preventative Maintenance

Preventive maintenance consists in carrying out, at predetermined intervals or according to prescribed criteria, checks intended to reduce the probability of a failure or deterioration in the operation of a system.

There are two types of preventive maintenance:
a). Periodic Maintenance
For each type of product, maintenance recommendations are laid out by the technical department. These verification procedures, intended to maintain systems or their subassemblies in correct operating condition over the targeted service life must be carried out according to the time intervals from lubrications, cleaning, etc.

b). Conditional Maintenance
To a certain extent, conditional-maintenance operations are a means to reduce (but not eliminate) the recommended periodic maintenance operations (thus limited to the strict minimum) that require an annual shutdown of the installation.

These operations are launched when programmed alarms indicate that a predefined threshold has been reached. (Number of operation > durability, aging indicators…) Electronic trip units in power circuit breakers can propose such functions. Conditional maintenance is the means to optimize installation maintenance.
