Reporting
Nowadays, thermographic inspections of electrical installations are probably, without
exception, documented and reported by the use of a report program. These programs,
which differ from one manufacturer to another, are usually directly adapted to the
cameras and will thus make reporting very quick and easy.
The program, which has been used for creating the report page shown below, is
called FLIR Reporter. It is adapted to several types of infrared cameras from FLIR
Systems.
A professional report is often divided into two sections:
■
Front pages, with facts about the inspection, such as:
■
Who the client is, for example, customer’s company name and contact person
■
Location of the inspection: site address, city, and so on
■
Date of inspection
■
Date of report
■
Name of thermographer
■
Signature of thermographer
■
Summary or table of contents
■
Inspection pages containing IR images to document and analyze thermal properties
or anomalies.
■
Identification of the inspected object:
■
What is the object: designation, name, number, and so on
■
Photo
■
IR image. When collecting IR images there are some details to consider:
■
Optical focus
■
Thermal adjustment of the scene or the problem (level & span)
■
Composition: proper observation distance and viewing angle.
■
Comment
■
Is there an anomaly or not?
■
Is there a reflection or not?
■
Use a measurement tool—spot, area or isotherm—to quantify the problem.
Use the simplest tool possible; a profile graph is almost never needed in
electrical reports.
