Thermography - Inspection and Report

The thermography report is an extremely useful tool for preventive maintenance, helping to prevent potential incidents (fires) and also contributing to energy savings.

Applicable to any type of consumer with electrical components, such as panels, substations, transformers, motors, etc., thermography is a tool capable of identifying hot spots in electrical components, preventing breakdowns and unnecessary interruptions. This means avoiding the burden on the consumer unit due to the need for corrective (or emergency) maintenance.

To prepare a thermography report, a specialized technician with a thermal imager is required, accompanied by a person responsible for the consumer unit to open the panels.

After the visit and inspection of the electrical components, the contracted professional generates a thermography report, sending the client the points where interventions are necessary to prevent further damage to the equipment and/or facilities.

​

Besides the issues related to maintenance, fire, and production losses, thermography also helps reduce electricity costs. Heated areas due to poor contact generate energy loss due to the Joule effect.

MTA (Maximum Allowable Temperatures)

​
To evaluate the components, there is a table for Maximum Allowable Temperatures (MTA), recorded by the Thermal Imager:

Contactors: from 100°C to 140°C

Fuses (Body): from 90°C to 110°C

NH Fuses (Clamp): 90°C

Terminal Blocks: 70°C

Insulated Wires: 70°C to 110°C

Metal-to-Cable Connections (Low Voltage 90°C): 70°C to 90°C

Metal-to-Cable Connections (Low Voltage Busbars): 90°C

High Voltage Disconnectors: 50°C

High Voltage Connections: 60°C
