On-site Dielectric Testing
We perform comprehensive dielectric safety testing with mobile on-site services to reduce downtime, lower costs, and ensure the safety of your operations.
Dielectric testing of equipment is crucial to meet required OSHA and ANSI standards. This ensures that the equipment provides the necessary level of protection for workers. We believe that no equipment is safe to use unless it has been thoroughly tested and verified.
Our dielectric testing capability involves applying high voltage between two conductors to assess insulating qualities, ensuring there is no arcing or excessive current flow. We provide both non-destructive and destructive testing to verify that electrical insulation can withstand transient or surge events.
The insulation is tested to ensure it will not fail due to aging, moisture, or wear from vibration.
Serving utilities, generators, electrical contractors, and regulators, we help protect workers, enhance safety, and increase efficiency.

Dielectric Testing
Prioritize safety for your team, stakeholders, and yourself with our hassle-free annual inspection services.
Dielectric testing is an inspection process that is crucial for bucket trucks, manlifts, tow trucks, boom trucks, utility trucks, and other commercial vehicles. In short, the inspection ensures that the insulation on all of the electronic components on your vehicle are secure and working properly. This helps to ensure the safety of your workers, on and off the rig—as well as the optimal performance of your equipment.
Bucket Trucks
All use of bucket trucks and other commercial vehicles are regulated by OSHA (the Occupational Safety and Health Administration) and ANSI (the American National Standards Institute), organizations that help enforce procedures and testing to keep workers and pedestrians safe in work zones and around commercial machinery.

In order to meet the legal requirements of using boom trucks and other vehicles, fleet owners need to maintain certain standards. This includes three mandatory tests—aerial lift testing, DOT testings, and dielectric testing—performed on an annual basis. If you need dielectric testing services for bucket trucks, please get in touch with us.

If your business uses one or more man lifts, tow trucks, or other commercial vehicles, dielectric testing (which, in the case of bucket trucks, is often called hi-pot, or high-potential testing) is not only recommended—it is required. Failure to comply with these regulations (or the failure to repair issues identified in a dielectric test) is in direct violation and could result in legal or disciplinary action.
In addition to ensuring regulatory compliance, proper testing (as well as the recording of the results) can help detect existing issues with your vehicles. This allows you to make corrections or adjustments that will prevent future problems, hazards, and safety concerns—as well as reduce the potential cost you will have from correcting said issues.
The barriers of electric insulation on your vehicle protect operators and surrounding pedestrians from dangerous electrical currents moving through your equipment. Through appropriate testing, you can ensure that the peak level of voltage does not exceed the resistance of the barrier material—keeping your equipment from being damaged and preventing human injury.
Dielectric tests can also evaluate the integrity of your equipment on multiple levels, depending on the type of test performed. For example, a dielectric strength test is designed to evaluate how high the voltage needs to be before the insulating material allows it to flow through. Alternatively, a dielectric withstand test measures the amount of time the insulation can hold a high voltage current before it begins to break down.

Acoustic Integrity
For this test, the computer will analyze the sounds your vehicle makes while it is operating. The technology calculates the stability of your equipment by comparing the size of the truck and the loads it carries. Then, it determines a quality score. This grade is evaluated on a scale to determine whether or not your vehicle meets the necessary criteria in order to safely operate.
Dielectric Integrity
According to the ANSI, a dielectric test verifies the electrical insulating strength in the FRP (Fibreglass-Reinforced Plastic) parts of upper and lower booms, buckets, liners, digger derrick extensions, tool circuits, and upper control systems on certain types of commercial vehicles. During the inspection, if any defects are found, the issues are classified according to severity.
Structural Integrity
In this inspection, different parts of the truck are evaluated for functionality and condition. Though the specific parts may vary depending on the type of truck, the parts inspected usually include a minimum of twelve points of inspection:
- Outriggers
- Chassis
- Elbow structure
- Machine platform
- Self-recovery device
- Digger (when applicable)
- Upper boom
- Material handler
- Lower boom
- Pedestals
In order to ensure that your vehicle passes inspection, it is crucial that you keep all of these parts in good working order with regular maintenance, repairs, and internal inspections. Other suggestions for proper maintenance of your vehicle can be found in manufacturer’s guidelines, owners manuals, and in the guidelines for your affiliated regulatory agencies.
Additional Tips To Pass A Dielectric Inspection
- Keep a calendar of required testing deadlines, repairs, and other maintenance requirements—and sync the dates with your devices.
- Keep your vehicle clean using the appropriate soaps and waxes.
- Maintain a policy to inspect every vehicle before and after each trip.
- Encourage operators to promptly report issues, repairs, and concerns with management, so that they can be verified and addressed.
- Keep a quick reference guide with all OSHA, ANSI, and any other applicable regulations for each vehicle.
- Keep your paperwork, records, repair receipts, and certifications organized and available.
