Electrical equipment safety testing

An electrical appliance can appear to work correctly without providing enough information to determine whether it remains safe to use. A power tool may start, its motor may run and the appliance may perform its intended function, but this says lit...

Technical drone inspections: thermal imaging, photogrammetry and 3D measurements

A drone used for technical diagnostics is more than a “flying camera”. It is a mobile measurement platform that can collect visual, thermal and spatial information from large or difficult-to-access assets in a short time. Depending on the task, w...

DNSH for investors: when are thermal imaging and blower door tests required?

For some projects financed with public funds, European funds or subject to additional environmental requirements, the DNSH principle—Do No Significant Harm—is becoming increasingly important. For an investor, this means demonstrating that a proje...

A refrigerator diagnosis in 30 seconds: the difference between diagnosing a problem and giving an opinion

Did the refrigerator really need to be replaced? PLN 200 was the price charged for diagnosing a built-in fridge-freezer in a kitchen. That would not have been remarkable if the diagnosis had not been made roughly 30 seconds after the technician e...

How to prepare for a thermal imaging survey

Thermal imaging can help locate areas where heat is escaping from a building. The usefulness of the thermograms, however, depends on the conditions during the survey and on how the building has been prepared. Stable indoor conditions, the weather ...

Thermal comfort: what is it and how can it be achieved?

Does the thermometer show an apparently comfortable temperature while the room still feels cold or stuffy? This may mean that thermal comfort has not been achieved. Thermal comfort describes a condition in which a person feels neither excessively ...

Thermal imaging inspections of electrical installations: guidance, standards and insurer requirements

What is a thermal imaging inspection of an electrical installation? A thermal imaging inspection is a non-contact diagnostic survey carried out while electrical equipment is operating. A thermal imaging camera records surface-temperature patterns,...

Partial-discharge detection with an acoustic imaging camera

What are partial discharges? Partial discharges (PD) are localised electrical discharges that do not completely bridge the insulation between conductors. They can develop at weak points in insulation, around sharp edges of conductive components, i...

BREEAM In-Use: a light-pollution reduction strategy for POL 06

As environmental considerations become more important in property management and sustainable-building assessment, reducing unnecessary night-time light is receiving greater attention. In BREEAM In-Use International Commercial V6, the subject appea...

Ventilation system measurements

A correctly operating ventilation system supports indoor comfort, air quality and the safe use of a building. Whether the property is a house, office or service facility, ventilation measurements help determine whether the system is operating in l...
