TABLE 13.11 Function of pertinence of the classification of thermography.
Zone Qualification Operation of machines

Zone [N] Normal (T # 34.5 F) Commissioned machines should generally
A operate in this area
Zone [P] Permiss´ıble It is acceptable for unrestricted operation for
B (34.5 F , T # 73.5 F) long periods

Zone [A] Alert Unsatisfactory for continuous operations for
C (73.5 F , T # 93 F) long periods

Zone [C] Cr´ıtical (T . 93 F) It is sufficient to cause damage to the

D machine at any time

conditions
Normal 76 at Commissioned machines should generally operate in
100% this area
Permissible 51 at 75% It is acceptable for unrestricted operation for long
periods.
Alert 26 at 50% Unsatisfactory for continuous operations for long
periods
Critical 0 at 25% It is sufficient to cause damage to the machine at any
time

The input variable thermography analysis level
Thermographic analysis is a third input variable, which can be used
as a load dispatch tool for power generation. The levels of analysis ther-
mographic were just subdivided into four variables, each corresponding
to the dynamic memory, the use of images thermal plants in the alert in
the reason. Materials and methods: Infrared radiation is a base of studies
on thermal images, which has a function of capturing this radiation, inter-
preting, and generating a quantitative image of the body temperature
studied [15].
Output variable “Technical condition of the motor”

The “estimated technical state of the engine” is the output variable of the
system, in relation to vibration (oil, water, iron, and copper). Table 13.12
