EXPERTS IN DRONE INSPECTIONS
WE'VE GOT THE KNOWLEDGE
CHP is S.F.O.C. Certified by Transport Canada ( Special Flight Operating Certificate ) to perform aerial Inspections during the day or night using multi-rotor UAV’s (drones). Using drones we can now get high-resolution, photos and videos using both high resolution cameras and Infrared cameras. CHP is trained by ITC ( Infrared Training Center) also know as FLIR in SUAS Level I Thermography Certification.

Forest Fires locating Hot Spots
Infrared Drone Scenario
Let’s say a cell tower provider, or any tall building or object for that matter, wants to see howtheir equipment is performing. Pictures or video can be taken of those areas safely with a drone. Using a drone reduces the liability or risk that’sinvolved sending someone to inspect the area.
Infrared Scans
Thermal imaging cameras along with drones are being used in many more Edmonton area industries than ever before. One of the most common is the roofing industry. Low slope roofs can now have an infrared scan taken of the whole roof allowing for detection of hot spots or infiltration caused by leaks in the roof membrane. Other Edmonton areas such as cell towers, water towers, electric lines, industrial stacks, search and rescue, fire departments and agriculture benefit from drone usage.
Industrial Drone Inspection
High Voltage
Each element of the distribution network is at risk of a series of defects that can result in energy losses and/or a major security risk. The breakdown of the electricity supply from a failure in the distribution network does not only affect the electricity supplier financially, but also a very high number of inhabitants, as well as companies and health facilities. Failures mean that direct threats to lives can occur. Therefore, all elements of the distribution network must be checked to prevent any of the mentioned problems.
One of the most frequent failures in the distribution network is the overheating of individual components due to transition resistance. Transition resistance occurs in imperfect places (damaged, out-dated or unprofessionally installed) electric joints. Due to the increase in series resistance, there are energy losses in the form of what is known as heat loss. It is not only economic problem but also a security problem – due worsening of parameters, the temperature of the damaged joint can increase its temperature until a fire breaks out that may be highly destructive due to the high voltage.
Thermal Image Joint on a High Voltage Distribution Line
Thermography is a technical field dealing with the issue of contact-free determination of the allocation of the temperature field on the surface of the measured body. Special measuring devices, known as thermal cameras are used for this purpose. A thermo-camera is able to state the surface temperature of the measured objects within a few meters (at a sufficiently high emissivity value). Using a thermal camera, the inspection can unearth problems that cannot be seen on a traditional camera and can lead to serious problems in the near future.
A major advantage of this method is that the inspection is always conducted for installations that are already in operation at full or partial operational loading. A technological shut-down is not necessary to conduct this inspection although its operation is required. Fully operating loading is actually better for the inspection.
The inspection is conducted within regular time frames because the problem can occur any time (due to ageing or the affect of climate conditions) including places that were previously fine.
Aerial Infrared Solar Panel Inspection
Thermal Imaging Locates Efficiency Robbing Defects in Solar Panels
We've got the equipment to detect anything
To achieve the most benefit from your Solar Panel investment all panels should be producing their rated power output. Defects in Photovoltaic panels (PV panels) will reduce efficiency through reduced voltage and current output. Two issues, which are typically found on solar PV panels, are defective Photovoltaic cells and defective converter boxes. Defective cells may found individually or as a group, however defective convertor boxes are seen as a single hot spot, not usually fitting within the pattern layout of the individual PV cells on the panel. To better understand the significance of having a single bad PV cell, please read the following section on how solar PV panels operate.
Infrared Rooftop Inspections
Infrared Rooftop Moisture Surveys
Infrared roof inspection is a proven method for detecting trapped moisture problems in flat roofs. Infrared roof Thermography can prevent equipment down time, production losses and help building owners and property management companies find roof problems when apartments below have become compromised by roof leaks. Due to the high cost of replacing a damaged roof, Thermal roof inspections should be performed whenever a building is purchased, sold, or leased. Infrared roof surveys provide the diagnostic information necessary for developing an effective roof maintenance program, planning capital budgets and for making informed decisions when considering roof repairs, replacement or resurfacing with one of the popular new roof coatings. Water enters a roof through defects in the waterproofing layer(s) due to deterioration, tears, cuts, poorly sealed penetrations, seams, failed flashings or caps causing the insulation to become laden with trapped moisture. The building experiences energy loss because wet insulation has a lower "R" value than dry material thus providing less thermal resistance. Our high-resolution Infrared thermal imaging cameras, find the trapped moisture as shown in the images above. Wet areas are identified and marked to show exactly where tactical repairs are to be made. By marking wet areas directly on the roof, they can be seen by building owners and roofing contractors after the survey is performed. Often, we find that the infrared survey shows is it is not necessary to replace an entire roof that only a few sections are "wet" and repairs can be made surgically to only these areas.
How It Works
During the day, the sun radiates energy onto the roof and into the roof substrate, and then at night, the roof radiates the heat back into outer space. This is called radiation cooling. Areas of the roof that are of a higher mass (wet) retain this heat longer than that of the lower mass (dry) areas. Infrared imagers can detect this heat and “see” the warmer, higher mass areas, during the “window” of uneven heat dissipation. Heat loss and other Thermal imaging services can be performed at the same time.

Search and Rescue With UAV's
EVERY SECOND COUNTS
In search and rescue operations every second counts. In order to function as efficiently as possible, it is important to be able to obtain a rapid overview of the situation… The type of view that is often only possible from the sky. The UAV payload system allows various devices to be attached to CHP’S UAVs. A Radio or a phone for communication, First aid kits, Water or food for example. A thermal image camera can assist in searches for missing persons, by identifying people in forests, fields, etc.
