5 2 the infrared thermographer will have sufficient knowledge of the components construction and theory of electrical systems and or rotating equipment to understand the observed patterns of radiation.
Infrared survey of electrical systems.
The infrared electrical systems survey is typically conducted on an annual basis as part of a regular preventive maintenance program.
70b is the recommended practice for electrical equipment maintenance while 70e is the standard that covers electrical safety in the workplace.
This paper discusses the national fire protection association nfpa 70e the occupational safety and health administration and.
An infrared electrical thermography survey can result in significant financial savings for the client by.
The two nfpa documents that have changed the face of infrared thermography over the last few decades are nfpa 70b and nfpa 70e.
5 3 the infrared thermographer will use thermal imaging and or measurement equipment with capabilities sufficient to meet the inspection.
If you are a facility manager maintenance manager building owner responsible for safety production and repair at your facility you cannot afford to be without a regular infrared ir thermographic survey of your electrical switchgear.
The survey identifies and records thermal patterns and temperatures of individual components within the system.
Because infrared thermography allows for system testing without any physical contact with sensitive electrical components these surveys cause no harm to the system.
The national fire protection association nfpa 70b 11 17 5 suggests that every commercial and industrial building in the united states should have an ir survey at least once a year.
Your facility s electrical systems are the backbone of your organization and without them your facility doesn t operate.
Increasingly insurance companies are requiring ir surveys of electrical and mechanical systems for their insured.
Since electrical panels must be removed thermographers often come in close proximity to energized components.
Reducing the risk of an unplanned electrical outage.
The infrared electrical testing allows for inspection of a large amount of electrical equipment in a short time as opposed to the alternative method of physically inspecting and tightening electrical components.
Infrared inspections of electrical systems provide a wide range of critical benefits.
This video demonstrates how an electrical infrared survey is performed.
Electricir infrared surveys are cost effective.
Stressed earth leakage units circuit breakers conductors and other electrical elements.
This is a non destructive technology which causes no disruption of service no shut down is required.
Survey more frequently depending on the equipment history or problems associated with its location or adverse environmental concerns.
Infrared thermography relative to electrical systems.
Infrared electrical thermography survey benefits.
Infrared electrical inspections performed per nfpa and insurance company recommendations can detect and document incipient failures and should be combined with timely effective repairs.
