Thermography Of Electrical Panels

Infrared electrical inspections find hot spots caused by defects in connections and components.

Thermography of electrical panels.

Businesses with high electrical demands should have a thermographic scan performed at least annually on critical systems such as circuit panels switchgears and transformers. 70b is the recommended practice for electrical equipment maintenance while 70e is the standard that covers electrical safety in the workplace. The two nfpa documents that have changed the face of infrared thermography over the last few decades are nfpa 70b and nfpa 70e. Some insurance companies require thermography to be done as part of their insurance requirements.

Thermography is a method of inspecting electrical and mechanical equipment by obtaining heat distribution pictures this inspection method is based on the fact that most components in a system show an increase in temperature when malfunctioning. In a typical manufacturing plant infrared thermography inspections did on electrical systems such as electrical switchboards high voltage distribution equipment motors corresponding controllers transformers and other control panels. They do this to mitigate losses. Electrical thermography can diagnose faults in electrical systems.

Based on the scan results a schedule to rescan should be based on the types of equipment power consumption and age of the electrical systems. Infrared thermography is used to find areas of excess heat caused by increased resistance so that problems can be corrected before a component fails causing damage to the component creating safety hazards and productivity loss. Stroma built environment delivers electrical thermography surveys and inspections to determine if electrical systems are operating as normal in order to reduce risks and any breakdowns. Infrared thermography is a test that can be utilised to identify unbalanced loads poor connections deteriorated insulation or any other issues in energized electrical panels or components without dismantling the components.

Using thermal imaging cameras we can help you to inspect electrical systems in your premises. Firstly in most countries thermography is not a legal requirement however there are other reasons that it should be done. Electrical thermography serves this purpose and helps you to detect any electric problem before it arises. Question how often does thermography have to be done on our electrical system answer.
