Electrical Surveys | SPR-Services Ltd

These surveys are non-invasive, relatively quick to carry out, cost effective and can form part of any predictive maintenance strategy.

Electrical components such as connections, joints and contacts are subject to deterioration over time due to corrosion, loosening, over tightening, contamination, and overloading, all of which causes an increase in electrical resistance and subsequently an increase in temperature. If left, further deterioration occurs, resulting in possible equipment failure, fire and even explosions.

Carrying out regular thermographic surveys results in your electrical distribution systems and components being evaluated and any maintenance intervention can be scheduled as part of a predictable maintenance strategy.

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

Fuse boards
Distribution boards
Equipment control panels
PLC systems
Motor control centres
High & Low main voltage systems
Electrical switchgear
Bus-bar systems
Transformers
UPS and battery systems

The survey is carried out by an ITC Certified CAT1 Thermographer, and a report is produced giving details of all the items surveyed, highlighting any faults, All temperature readings are compared to manufacturer data sheets and where possible to other similar components to not give false information. The engineer will thermally tune the images to give a clear understanding of where the heat is being generated.

A survey report will also demonstrate that as a business you are taking positive action to ensure that your electrical infrastructure is of a reasonable condition and that regular maintenance is being undertaken. This also demonstrates that you are taking reasonable steps in relation to fire prevention in the electrical systems as it is becoming more and more relevant as insurance companies require or recommend Thermographic surveys as part of their Fire risk assessment of your business.
