At Hexo Electrical Testing we offer an Electrical Thermographic Survey service to our commercial clients. A thermographic survey is usually used to supplement regular EICR testing, and the recommended frequency is once per year.
Why have a thermographic survey?
An electrical thermographic survey carried out by a skilled electrical inspector will identify any unusual hot spots in the fixed electrical installation.
It does not require any down time for the business as the survey is performed live and under normal operating conditions, so nothing is turned off. In fact, we need the installation to be under load so we can detect any issues using an electrical thermal imaging camera.
A thermographic survey should be carried out once per year between EICR testing intervals.
Reliable Service with 100% Satisfaction
What is checked during an electrical thermal imaging survey?
Areas that will usually be checked are:
- Distribution boards
- Bus bar chambers
- Contactor enclosures
- General enclosures and junction boxes
Typically, the survey will highlight any:
- Loose connections
- Overheating circuit breakers or fuses
- Abnormal loading
- Overheating distribution equipment
What happens after an electrical thermal imaging survey?
If any issues are detected, then we can undertake remedial work and rectify the problems to make the installation safe.
The process is quicker and much less disruptive than EICR testing but should be undertaken in conjunction with a regular Commercial EICR.
It’s an excellent way to maintain a safe fixed electrical installation, and in most cases insurance companies will reduce premiums if thermographic surveys are undertaken, as the risk of an electrical fire is reduced.
Who needs a thermographic survey?
An electrical thermographic survey is recommended for all commercial premises and businesses as it is an excellent way to be vigilant and reduce risk of dangerous electrical defects.
Your insurance company may insist that you have a survey undertaken, or one may be incentivised by a reduction in premiums as it is a recognised method of reducing electrical incidents.
How much does a thermal imaging survey cost?
Electrical thermal imaging survey costs depend on how many items we will be inspectin
g. As we are an electrical inspection and testing company, we do not require a separate competent person to open the electrical items for us, so there will be no additional costs by using us.
Please contact us to discuss your requirements and we will provide you with a fixed price for your electrical thermographic survey.
How often should a thermographic survey be carried out?
It is recommended that a thermographic survey is carried out once per year, in between a regular Commercial EICR.
Is there any disruption?
There is minimal disruption as because we use an electrical thermal imaging camera, we do not need to isolate any electrical supplies, so all power will remain on.
We will need to gain access to every piece of equipment that is to be inspected and then open this equipment to perform the thermal imaging survey.
