They are all common to a three-phase, 150 amp breaker such as this:
Unlike any other inspection company, our infrared electrical P.M. inspection utilizes a load-based temperature standard, derived from Ieee/ANSI standards in evaluating componet temperatures.
This standard gives the acceptable temperature rise of a componet for the load it’s carrying. This allows for greater accuracy in problem diagnoses than simply looking for hot spots and high temperatures.
As an example: Which breaker problem below is the most severe?
Each problem has a loose center-phase connection on its load side.
Using temperature alone, our competitors would rate these problem as follows:
Load readings, If taken at all, are only used as a rough correlation with temperature.
Did you pick problem “C” as the most serious?
Using our IEEE/ANSI based standards Pro-Line’s analysis is quite different!
THE DIFFERENCE IS LOAD!
The breaker above is the same breaker under variable loads!
Pro-Line’s IEEE/ANSI load based standard shows this component’s temperature rise
at about 240% of the maximum allowable rise, at any load current!
If your infrared testing company can’t accurately analyze component problems,
how can you rely on their results?
