Non-destructive test
Test performed on a machine applying a voltage lower than the manufacturer‟s
recommended maximum.
Part
Parts making up a component (gaskets, bolts).
Permissible condition
The admissible state of an item for a specific use. This may never be below that
required by the official and technical regulations for each such use. Equivalent to the
term
Admissible State .
Phase
Each of the single phase currents that make up a multiple phase system. This term
usually includes the conductors, windings, etc.
Phase winding
Set of spirals forming a multiple phase winding.
Power
Product of the voltage applied to a circuit by the current circulating in it. This is
measured in watts (W).
Predictive Maintenance
Preventive maintenance based on knowledge of the status of an item through the
periodic or continuous measurement of a significant parameter. The intervention of
Maintenance is conditioned to the prompt detection of symptoms of failure.
Preventive Maintenance
Maintenance consisting of performing certain repairs or changes to components or
parts, on the basis of previously established time intervals or certain criteria, to
reduce the probability of failure or loss of performance of an
item . This is always
scheduled.
Rack
Frame supporting electronic equipment .
Recovery voltage.
It is the voltage that appears on the terminals of a dielectric previous charged, and it
was applied a short circuit in it for a determined time.
