The power generation industry, including coal, natural gas, hydro, solar, wind and nuclear, has the some of the most vigorous electrical preventative maintenance requirements in the electrical power maintenance industry. Certain critical electrical systems, such as isophase and segmented busbar systems leave power generation industry extremely vulnerable due to inaccessibility issues. These systems are the only critical components that usually have no design redundancy. The internal components of isophase busbar systems are impossible to inspect under load because they do not have covers over each joint that can be easily removed. Electrical Maintenance Safety Devices (EMSDs) such as FlexIR range of product lines are extremely useful in helping asset owners identify issues before outages, allowing for more efficient outage planning and prioritization of needed repairs.
Fossil Fuel & Nuclear Generation
Safety and reliability concerns in fossil fuel and nuclear generation facilities drive the need for regular condition based maintenance inspections of the electrical infrastructure. EMSD’s can facilitate both faster and safer IR and Ultrasound inspections.
Renewable (Solar & Wind)
Larger power inverters and step-up transformers used in Utility Scale renewable power plants should be Infrared (IR) inspected for thermal issues at least on a quarterly basis. These critical assets are both costly to repair or replace but also may have significant lead times leading to large energy harvest losses if they fail.
The Medium Voltage switchgear in hydroelectric generation plants is critical to ensuring electricity generated can be safely and consistently transmitted onto the grid. Reliability of these assets can be increased through regular Infrared (IR) and Ultrasound inspections.
Distribution Utilities operate significant unmanned Medium Voltage assets at remote sites that can benefit from regular CBM inspections. Due to the high fault current levels at these sites, EMSDs can ensure risks to personnel are minimized.
The IRISS Difference
Unparalleled Field of View (FOV)
The large format IRISS CAP series windows and custom infrared windows have a far superior field of view. The CAP-ENV 24 series has over 12 times the FOV of a 4-inch diameter round window which gives the thermographer infinite viewing angels inside the switchgear through one IR window. Reducing the number of infrared windows needed typically reduces procurement and installation cost by over 50%.
Fixed & Stable Transmission
Our polymer IR window systems maintain fixed and stable transmission (FAST) for the life of the installation ensuring that the temperature data collected through the IR window is accurate and reliable for the whole life of the installation.
A Powerful Case for Infrared Windows
A regional Power Generation Facility had been tasked by their insurance carrier to perform regular preventive maintenance on the switchgear within their facility. Unfortunately, regular downtime was not a practical option for them as the processes required to do the live inspections were hazardous and required more manpower and resources than they had to provide. In addition, they too were feeling the pressure of the requirements of NFPA 70E and were starting to re-think their strategy since inspections of energized electrical equipment was becoming more restrictive, more time consuming and more costly
