Infrared Scanning Of Electrical Equipment

The value is that we are now able to predict an electrical fault before the element fails completely.

Infrared scanning of electrical equipment. Basically all objects emit thermal energy which can be viewed with a scanner whose purpose is to convert the radiated electromagnetic thermal energy to electronic video signals. Infrared scanning works off the principle that electrical equipment gives off heat but malfunctioning or overloaded electrical equipment will give off excessive heat due to increased electrical resistance. Today s facilities engineers are avoiding costly expenses every year with infrared electrical surveys. While the act of infrared scanning in itself doesn t require contact with equipment voltage and current measurements may be necessary and pose a shock hazard to qualified persons.

Infrared thermal imaging inspections detect hot spots and other defects. Before an electrical component burns up it heats up. Electrical shock is another hazard to consider especially when working around open electrical equipment in small areas such as an electrical closet. Loose connec ons imbalanced and or overloaded circuits defec ve breakers damaged switches faulty fuses and material defects all lead to equipment failure.

It is the part of the electromagnetic spectrum perceived as heat. Infrared scanning is used to inspect electrical equipment because excess heat is usually the first sign of trouble. Routine infrared inspections of energized electrical systems should be performed annually prior to shut down. More frequent infrared inspections for example quarterly or semiannually should be performed where warranted by loss experience installation of new electrical equipment or changes in environmental operational or load conditions.

On a typical infrared scanning procedure a northeast testing technician starts with a list of all electrical and mechanical equipment to be inspected. An infrared electrical systems survey scan can substantially improve profitability and reduce your operating. Using infrared scanning as an early. Infrared thermal scanning of electrical equipment infrared thermography is a valuable tool in determining the condition of electrical equipment.

After obtaining familiarity with the hospital an experienced technician is able to inspect and record condition of equipment quite fast. Infrared thermography is used to perform pd pm inspections on electrical equipment because excess heat is usually the first sign of trouble on electrical or mechanical apparatus.
