Preventative Electrical Maintenance

Grohs Electric prepares Infrared Thermograghy reports that provide detailed information and insight on electrical issues before they turn into major problems. Infrared Thermograghy can be a time saving approach to a preventative maintenance program. When used in conjunction with other diagnostic tools, Infrared Thermograghy can help in preventing major electrical problems. Not all electrical problems can be detected with Infrared Thermograghy alone.

Thermography Reports

The images that are present in the Thermograghy reports are produced to show the difference in heat between two objects with emissivity rated as close to .95 as possible. A rise between two objects under the same load outside the parameters in the report is known as a "hot spot". The reports are generated in the format of "white being hot" and "black being cold". The hot spots in question should then be analyzed further, taking into consideration the difference in temperature between the two objects under the same load.

Color Temperatures

The different colored cursors on the images indicate different temperatures based on the color of the cursor, the component being tested and reference values. Infrared Thermograghy becomes a sneak peak into electrical components to determine if they are within operating temperature tolerances. If not, this becomes a flag for further diagnostics, all in an effort to catch electrical failures before they become major problems or safety concerns.



Thermal Imaging Surveys are non-invasive and non-destructive, allowing the imaging survey to be completed while plant and equipment is running, in production and on load.

Thermal Imaging Surveys are real time and produce fast, accurate and immediate temperature measurement and fault detection.

Thermal Imaging assists businesses in complying with Federal, State and Local electrical maintenance regulations and ordinances.

Thermal Imaging assists businesses in complying with insurance requirements and complements their existing risk avoidance measures.

Thermal Imaging can be incorporated into existing predictive and preventative maintenance programs.

Thermal Imaging increases energy efficiency, capital equipment lifespan and safety by reducing the risk of fire.
