Thermographic Survey of Electrical Systems – NZ

Here is exactly why a regular thermographic survey of company electrical systems is so important.

I inspect switchboards for many different private, commercial and insurance companies right across NZ, but the latest infrared electrical inspection in particular was quite interesting… for all the wrong reasons (In my opinion).

When you have a 24/7 operation, a thermal imaging survey every 6 months should be strictly enforced… not every 9 or 12 months. Recently, I was called out to an oil rig that had just experienced a fire in one of the main switchboard rooms nine months after the first thermographic inspection was carried out. If this company had maintained a strict policy for every 6 months, then this hot spot/fire hazard would have been picked up well in advance. To make matters worse, it was at 1:00am in the morning when the alarm went off. The crew of 40+ workers woke up to a fire on a ship full of oil. Not good. Put yourself in that position!

Upon the re-inspection of the surrounding switchboards in the same electronics room, I found another huge hot spot caused by a loose connection on the back of a sea water injection pump. The temperature at the connection was 167 degress! Here’s the photo…

Hot Spot Caused by Loose Connection

This was a large offshore operation, so it was easy enough to shut this pump down and switch to the back up pump. It didn’t end there…

Next… I was thermal imaging a lighting panel in the engine room, and suddenly a glowing 92 degrees hot spot was coming off a 20amp breaker. Further testing showed 27 amps running through. It turns out the breaker and cables were under rated. One fire and two potential fires found within 3 weeks… this is not a record to brag about… but it can happen to any company who turns a blind eye to the importance of electrical system faults.

Remember, it only takes one hidden loose connection to potentially ‘bring the house down’. This is why some insurance companies now require thermal imaging prior to issuing a policy.

If you are considering a thermal imaging thermographic inspection, then now is the time. As the above company recently found out, it can turn out to be very expensive if you just ‘hold off’ for a few weeks or months… or not at all. More electrical fault photos here

I enlisted Dean’s services 2 days prior to “D-day” of us purchasing our first NZ home. Dean proved to be an extremely efficient and knowledgeable technician. He has a very good understanding not only of his specific field, but also of general building requirements. He was easily able to spot, and talk me through, existing as well as potential problems, and was very open to answering the myriads of questions I fired his way. Most importantly, he gave me non-biased answers, allowing me to make an objective decision regarding the purchase of a potentially leaky home. Thanks again for excellent service Dean!

We have lived for some time in an old weather board cottage which we have renovated over a period of years. Recently we discovered a leak, so we googled “find a leak” and found a comprehensive and detailed website of the same name. Next we spoke to Dean and an appointment was made. He was punctual, courteous and his experience was obvious. His thermal imaging equipment is ‘state of the art’ and the source leak was quickly detected.

Dean was able offer practical solutions which we can act on with confidence. As a result of this experience we would recommend the use of his skills before the sale or purchase of any property to be reassured as to the integrity of the property. Dean is personable, a superb communicator and a true professional. Maggie & David M - Waiatarua

Dean was very professional and I would highly recommend anyone that is thinking of buying a property to get thermal testing done. Fortunately it was by pure chance that I even knew these tests were available after speaking to my neighbour and he advising me. The house we were looking at had water leaks and Dean has saved me many thousands of dollars in the long run. David G - West Auckland

Dean is a very professional and friendly guy. He goes step by step through the process which is very valuable. When he finds a potential problem he immediately notified to me and discussed with me in details on what actions could be taken. Anyway no major problems were detected in the property I wanted to purchase. However I greatly advice anyone to obtain Dean's professional service to make sure the property is in a satisfactory condition. Robbie P - Glen Eden

Thank you very much for the great service, very professional and appreciated the time taken to explain the process. Very glad to know that with all the stigma that goes with plaster houses, ours is not a leaky home. The report has helped pin-point some areas for maintenance which we plan to undertake sooner rather than later..Thanks again. Heather M - Maraetai

We were a bit apprehensive about what the leak detection might find, but found Dean’s confident, friendly and very capable approach extremely reassuring. While we were greatly relieved by the findings concerning the exterior of the house, Dean’s thoroughness in looking also for internal issues uncovered a surprise bath leak. Thanks Dean for solving the mysterious odour that’s been bothering us for the last 6 months! We highly recommend Dean to anyone with even the slightest concerns regarding moisture in their homes. Kevin - West Auckland

Thank you Dean for your prompt service. I was given 2 days to have a Building inspection done which found some dampness in the house. It was well worth the money spent as Dean found some other damp issues. He was very thorough and very informative and even though there were issues with the house they were all fixable so I was then able to re negotiate the purchase price. I would recommend anyone buying a house- any type of building structure to have ’Thermo Imaging’ as part of a building inspection. Thank you once again. Maree, Glendowie

We had some concerns about a recently renovation house including a lower basement. Being nosey I popped around to join Dean on his inspection. Apart from enjoying meeting him, Dean was enormously informative, approachable & friendly, I found the technology & information I gleaned fascinating. Fortunately, we identified no significant issues with the property. It gave us great peace of mind & we can enjoy our new home knowing we have bought a dry, water tight property with with hidden surprises. Thank you Dean for your help & reassurance. To my mind it is certainly worth the modest sum versus potential costs you could incur which could also mar one of most expensive purchases of your life.. Diane - Devonport
