Save on Insurance Premiums with an Annual Electrical Thermal Survey

Category: Energy Efficiency

No matter how big a business gets, it will always be at the mercy of a few major failings that can bring everything grinding to a halt.

Benefits of an Annual Electrical Survey

Electricity, of course, is the backbone on which everything in a modern business operates – no electricity means no internet. In turn, that means lost productivity and scrambling around desperately contacting clients and trying to mitigate the damage – hardly ideal.

As well as offsetting disasters like this, an annual electrical thermal survey can also save businesses a good amount of money and ensure safety is at the highest level.

Requirements and Savings

In addition to making pre-emptive savings on major problems in the future, there are also other benefits to undertaking an annual electrical thermal survey.

Some insurance companies providing business cover insist on a pre-emptive thermal survey before providing cover. This is to help the company identify any major faults and check the general level of safety and associated risks of a business before providing cover.

In addition to free electrical thermal surveys, many insurance companies look favourably on businesses that undertake annual electrical thermal surveys. This could result in discounted premiums and substantial savings and, at the same time, ensures the business remains safe and up to code. This greatly reduces the likelihood of major problems and swollen premiums, making for great savings all over.

For any business in the know, an annual electrical thermal survey makes perfect sense.

Faults and Hazards

Any business – call centres and data storage centres, for example, that uses a large amount of electricity, requires a complex and large wiring system. The more complex something is, the more chance there is that something, somewhere will fail.

As most good businesses know, it is always best to head off problems at the pass before they can do real damage, and that is what an annual electrical thermal survey is really all about. An electrical thermal survey can help reveal a wide range of faults – whether they come from poor workmanship or natural material fatigue.

Whatever the reason for a potential electrical fault, they will always reveal themselves in the form of higher temperatures or ‘hot spots’ that indicate unusual and dangerous areas that require further investigation and attention.

Some of the faults that an annual electrical thermal survey can reveal:

  1. Fatigued and perished connections
  2. High resistance circuits
  3. Overheating contactors and lighting circuits
  4. Overheating and faulty fuses
  5. Internal circuit breaker faults
  6. Loose, dangerous cable connections

Any one of these faults could have big consequences for worker safety, not to mention building damage and repair costs, as well as lost productivity and business. An electrical fault that does real damage does not simply last the duration; it ripples outwards and takes a long time to fix all of the problems caused.

An annual electrical thermal survey can stop these problems in their tracks, making them into a simple repair job before they become a total disaster.

As most business sites are bustling with employees and the important work at hand, the last they need is an invasive, intrusive series of tests that disrupt the workplace.

This is why electrical thermal surveys prove so popular with businesses – especially bigger sites, where every minute of the workday is important, as the survey is totally non-disruptive.

A non-contact method, the beauty of an electrical thermal survey lies in the fact that it sees what we cannot. As it sees hotspots of heat through building materials and other surfaces, there is no need to disrupt office life and move furniture or close down work areas.

There is no need for probes or clambering into every corner of the office. All an annual electrical thermal survey requires is the thermal camera itself (perhaps more than one for covering a large site) and experienced operators.

An operator with skill can quickly identify troubling hotspots and note them down, all without moving a single piece of office furniture or disrupting workflow.

As an example, a typical survey would proceed as follows:

  1. Draw up a schedule of the equipment and areas that requires testing, including location and ID.
  2. The thermal surveyor notes each item and its average temperature into a file. This enables future surveys to compare temperatures between surveys and not any changes or potential problems.
  3. Thermal imaging takes place, noting any hotspots and faults, with regular photography and detailed fault sheets to document and accompany the report.
  4. A complete ‘Fault Sheet’ details faults or problem areas, how severe it is and advised timescale for action.
  5. The final report includes all thermal results and scaled, recommended actions on any faults.

A comprehensive annual electrical thermal survey only requires a team on site with equipment to identify most faults. The nature of thermal photography makes the whole process much less invasive than other health and helps reveal potential problems before they become real.
