Pro-Line Inspections has been setting the standard for infrared inspections for over 35 years. Implementing an infrared inspection program produces measurable cost savings. On average, for every $1 spent on a Pro-Line infrared electrical inspection, there is a $4 return on investment, as the Pro-Line technician will identify equipment problems allowing repair before costly failures.
Our services include:
The infrared inspection is an important form of non-destructive testing that has become an indispensable predictive maintenance tool. Unlike any other inspection company, a Pro-Line infrared electrical predictive maintenance inspection utilizes a load-based temperature standard, based on IEEE/ANSI standards and Ohm's Law in evaluating component temperatures.
This standard gives the acceptable temperature rise of a component for the specific load it's carrying. This gives greater accuracy in problem diagnoses than simply looking for hot spots and high temperatures. The infrared inspection is an important form of non-destructive testing that has become an indispensable predictive maintenance tool, and is performed with a portable infrared imaging system. This equipment detects infrared energy (heat) emitted from an object and displays it as a dynamic thermal image, producing a variety of colors. Each color represents a discrete increment of temperature as noted by the temperature scale.
Pro-Line uses a nationally recognized standard in evaluating the severity of component problems found during the inspection. The IEEE/ANSI Standard aid in the evaluation of component temperatures. It specifies the maximum temperature for all components based on their percent of rated load at the time of the inspections.

Corona is a serious issue that can occur in switchgear 2000 volts or greater.
In metal clad switchgear, the most serious result can be a flashover causing enormous damage and personal injury. Corona results from ionized air or ozone caused by damaged insulation, contamination and faulty design. The byproducts of corona, nitric acid and carbon, cause a continuous decay of insulation making the situation highly unpredictable. The ozone is conductive and supports the flashover.
With the correct ultrasound inspection, corona, tracking and arcing can be detected and remedied before serious results occur.
Infrared imaging offers a tool to detect and accurately map subsurface roof moisture. Under the right conditions, infrared surveys can assess every square inch of roof surface.
As the entire roof begins to cool after sunset, areas with trapped subsurface moisture will retain the sun's heat longer than normal dry areas. These abnormal areas are depicted as warmer areas on the viewing screen of infrared imaging equipment. Moisture readings of these areas provide a quantitative indication of those moisture levels.
Thermograms, conventional photographs and a roof plan documenting the location of wet areas can be provided in a comprehensive report. Based on this, management can make informed decisions regarding roof repair or replacement. Infrared imaging offers greater potential for detecting and accurately mapping subsurface roof moisture than other non-destructive testing methods.
Infrared surveys can assess every square inch of roof surface; it is usually performed at night by walking the roof. As the entire roof begins to cool after sunset, areas with trapped subsurface moisture will retain the sun's heat.
The exterior of a building is also called the "envelope". The insulation, outer walls, ceiling, doors, windows, and floors all work together to control airflow in and out of the structure, repel moisture, and prevent heat from being lost or gained inside your facility.
The goal of the infrared building heat loss inspection is to reduce energy and repair costs, evaluate construction quality and building performance, enhance occupant comfort, health, and productivity, and improve the marketability of the properties. An infrared scan of the building envelope can help certify a building for LEED certification.
In most buildings, the envelope is relied upon to absorb the energy difference between inside and out. This puts a lot of stress on the barrier materials within the envelope assembly to provide a variety of ways to respond to the changing external environment.
An envelope assembly is designed to a minimum tolerance and a failure in any one of the components within the assembly will significantly reduce the overall performance.
Risk assessments for shock and arc flash are driven by the NFPA 70E® requirement. Risk assessments can be used to determine the voltage and shock boundaries within a facility. If the risk assessment determines that an arc flash hazard exists, Allied's electrical consultants can help you determine safe work practices, the arc flash boundary, and the required PPE.
Pro-Line Inspections Offers Arc Flash, Short Circuit, and Coordination Studies necessary to meet new regulatory requirements.
This service can be performed in conjunction with the infrared survey at a cost savings to the customer.
Arc Flash Hazard
An arc flash hazard is a dangerous condition associated with the possible release of energy caused by an electric arc. This occurs when a grounded object comes in contact with an energized object. This low impedance path creates a short circuit and an electrical arc. An arc flash is measured in calories per centimeter squared (cal/cm²). For example, one calorie would be the equivalent of holding your finger over the tip of a lit match for one second. An Arc flash produces some of the highest temperatures known on earth, up to 35,000°F, that is almost 4x hotter than the surface of the sun (9,000°F). This heat can vaporize nearly all materials on the face of the earth.
Short Circuit Study:
The short circuit study is a required part of any arc flash study. The reason for this portion of the study is to determine the amount of available short circuit current in the power system. This available fault current at each point in the power system is then compared to the specific breaker or protective device's operating/trip time. The device's operating/trip time determines the amount of arc flash energy that could be released at each point in the power system. The short circuit study also verifies that each piece of equipment has an adequate interrupting rating for its' position in the power system.
Protective Device Coordination Study:
The coordination study is a very important part of the overall arc flash study. Nearly all breaker manufacturers ship their breakers with factory minimums. Many breakers in the power system have (multiple) different settings that can be field adjusted to control how fast the breaker trips, in the event of a short circuit condition. The breakers in the system are adjusted in order to minimize the arc flash energies to their lowest possible values, while still providing the highest level of electrical system reliability and eliminating nuisance tripping. If a coordination study was not performed when the breakers were first installed, it is no longer a question of IF problems will occur, but WHEN will they occur. Just one 20 amp circuit can take down an improperly set 4000 amp main breaker, and shut down the whole building.
The installation and use of MIKRON Access/Viewports in high voltage panels eliminates the need to remove switchgear covers during infrared and ultrasound testing. This greatly reduces the risk of damage and injury from arc flash incidents and reduces inspection time.
The MIKRON Viewports do not lower switchgear ratings nor do they have the fragile windows that block part of the infrared radiation like competitive units.
MIKRON Viewports are approximately 1/3 the cost of competitive units. In addition, MIKRON units are the only kind that accommodates ultrasound corona detection surveys.
An important application of infrared testing is the inspection of insulated process vessels, boilers, and heaters, such as those used in petrochemical industry. These vessels are lined with refractory insulation to protect the metal skin from the high temperatures and caustic properties of the product.
Over time, this insulation deteriorates and must be replaced. An infrared inspection of the exterior surface of the vessel permits thermal mapping of the unit. Temperatures are verified with a surface temperature probe allowing for differences in emissivity.
The customer is provided with the information necessary to accurately schedule shutdowns so that faulty components can be repaired before they cause severe damage or injury due to failure.
The insulation inside boilers, heaters and ovens will also deteriorate over time. To operate these units safely and cost-effectively, an infrared inspection should be performed on an annual basis. The information provided from an infrared inspection, along with other PM tools will help you maintain your equipment in top condition.
Solar power installations reduce environmental impacts from fossil fuel power generation due to their low air emission of pollutants and greenhouse gasses during operation. When photovoltaic systems (PV systems or Solar panels) operate at an optimal level, they are a great source of clean energy.
Over time, solar panels may develop defects, which can effect functionality and become a safety hazard. This can cause severe drops in energy production and may become a fire hazard if left unaddressed.
Solar Panel Inspection
A regular infrared inspection of your rooftop solar panel system is a safe and effective way to check for defects and potential fire hazards before they become a safety or production problem. Pro-Line Inspections, Inc. has identified three applications for conducting a non-invasive, non-destructive infrared inspection of solar panel systems.
Quality Assurance: Scanning the arrays during installation will show defects that may have occurred.
Preventative Maintenance: Scanning installed systems on a regular basis will allow for the identification of defective areas due to inclement weather, material defects, and/or maintenance upkeep.
All applications include a report containing thermographic (infrared) and conventional photo documentation of the solar panel system. Any defects found are outlined and notated on an aerial view map (if applicable) as well as documented in a spreadsheet format.
At your request, Pro-Line Inspections can perform an infrared inspection of the electrical equipment associated with your solar panel installation (breakers, inverters, combiner boxes, etc.). Documentation will include; thermographic (infrared) and conventional photos, temperatures, a list of equipment inspected and analysis (where appropriate) in a PDF report. Photo documentation will be provided only for problems found.
