ELECTRICAL THERMAL IMAGING

There are millions of switchboards and control panels throughout the country that have faults that can’t be seen by electricians. Electrical thermal imaging is the most efficient way to detect faults, hot spots and loose connections. Studies show electrical thermographic inspections have a pay back to the client of 4:1.

Thermographic systems are commonly used for Electrical Infrared Inspections . As electrical connections become loose, there is a resistance to current that can cause an increase in temperature. This increase in temperature can then cause components to fail, potentially resulting in unplanned outages and injuries. In addition, the efficiency of an electrical grid becomes low prior to failure, thus energy is spent generating heat, causing unnecessary losses, not to mention monies that could be saved. If left unchecked, heat can rise to a point that connections melt and break the circuit; as a result, fires may occur.

Besides loose connections, electrical system suffers from load imbalances, corrosion, and increase in impedance to current. Thermography can quickly locate hot spots, determine the severity of the problem, and help establish the time frame in which the equipment should be repaired.

Thermography is very useful when inspecting indoor components such as motor control centers (mcc), breaker panels, disconnect switches, and transformers.

Additionally, outdoor components, substations, switchgear, transformers, and outdoor circuit breakers can be inspected quickly and efficiently with infrared thermal imaging.

Another benefit of thermography is the ability to perform Electrical Infrared Inspections while they are under load. Since thermography is a non-contact diagnostic method, a thermographer can quickly scan a particular piece of equipment from a safe distance, leave the hazardous area, return to his office and analyze the data without ever putting himself in harm’s way.

Electrical Infrared Inspection: Client Responsibility

During the Electrical Infrared Inspection , the client is expected to provide a qualified technician to accompany the infrared thermographer. The technician will be responsible for providing access to all equipment, including the opening and closing of enclosures, and supplying amperage readings where necessary to ensure thorough inspection.

Additionally, the technician must be familiar with the systems that are inspected with regard to load, conditions and history of the components that are inspected.
