Electrical Thermal Imaging Surveys

Electrical thermographic surveys can identify poor connections, overloaded circuits, failing components or imbalanced loads. Any faults on electrical systems are expensive in terms of plant downtime, damage, loss of production or risk from fire.

Surveys are carried out while electrical supplies are live and no interruption to your power will occur during the course of the survey.

Fuseboard Fault

Fuseboard Fault DigitalarrowFuseboard Fault IR

Faults of fuseboards usually only come to light when they burn out or completely fail causing risk of fire or plant disruption. A survey will highlight problem areas and we will tell you in our report exactly what you need to do to repair the fault.

We regularly survey and locate faults on all types of electrical systems ranging from 132,000 volt power transmission systems through to industrial 415 and 12 volt systems. Huge benefits can be obtained from a quickly performed survey of your electrical distribution system and control panels.

Major Fault on Critical Supply to Hospital

Major Fault on Critical Supply to Hospital DigitalarrowMajor Fault on Critical Supply to Hospital IR

This fault was identified during a routine inspection of a hospital electrical distribution system. Critical temperatures were found which if left much longer would have resulted in a major power outage and significant damage to a whole wing of the hospital..

An electrical survey is ideally suited to identifying faults within electrical systems, because power does not need to be turned off and no direct contact is required.

Control Panel Fault

Loose ConnectionarrowLoose Connection IR

We have identified thousands of faults within control panels and switchgear. Very often the repair involves just re-tightening a connection but left alone would result in a burn out and plant downtime costing potentially thousands of pounds.

We recommend regular thermographic surveys of the following types of equipment:

  • Fuse boards
  • Distribution boards
  • Busbar systems
  • Control panels
  • High voltage and medium voltage systems
  • Power line connections and insulators
  • Switchgear
  • Electronic components
  • UPS and battery systems
  • PLC connections
  • Motor control centres

Pixel Thermographics can carry out a thermal imaging survey to your own requirements or will offer advice on the extent of a survey.

Battery Charger Connection

Poor Battery ConnectionarrowPoor Battery Connection IR

Battery connections to fork lift trucks or cleaning machines are often abused and damaged. We regularly identify faults on items which are very close to ignition temperatures. These pieces of equipment are often in secluded areas and left on charge overnight which heightens the risk of fire and major damage to buildings.

Prior to a survey we will provide a full risk assessment and method statement detailing how we conduct the survey and the precautions we take to ensure our work is completed safely and efficiently.

Issue of the Week - May 2016 - Week 4

We have located hundreds of flat roof leaks over years of carrying out investigations and surveys.

Leaks come in all different shapes and sizes and very often the ingress point (cause of the leak) is not where the client expected it to be. Our surveyors are highly experienced in conducting inspections and surveys to locate the source of water ingress.

The leak site shown in the image above is a typical problem we find on many roof systems and is a defect on the pointing around a lead flashing detail.

This particular failure was located just below an angled section of wall which was directing rainwater directly into the gap which was then making its way into the office below.

The leak had remained unsolved for 2 years prior to our arrival and we also identified 3 other water ingress points.

Issue of the Week - May 2016 - Week 1

A compressed air leak survey will locate all leaks on a site and once located we:

 Take Details of the Location and nature of the leak
 Individually number each leak
 Photograph the leak
 Cost each individual leak

A report is produced which details all compressed air leaks found and is issued to you within 5 working days.

The image above shows a leaking regulator valve body which was costing the client over £500 per year in wasted generating costs!

Thermal Imaging Survey - Issue of the Week - April 2016 - Week 4

Things are hotting up on the thermal imaging front (pardon the pun) and we have decided to keep the page updated with an 'Issue of the Week' section!

This week is a good old fashioned electrical fault identified during an electrical thermographic survey at a hospital which was picked up by Stuart Robinson.

This is a main supply to a distribution board where a loose connection was identified. The site engineer was on hand to carry out the repair as directed by Stuart. The second image shows that the repair has been carried out successfully and a major problem was averted!
