Works Needing  Electrical Certification

Works Needing Electrical Certification

Electrical certification The regulatory system promotes  safety by, amongst other things, specifying who can carry out electrical work, how it is certified and what standards apply. In order to achieve the objective and requirements of the legislation, the scope of...
Closure of BESS Scheme

Closure of BESS Scheme

The BESS scheme  was a voluntary scheme initially introduced in 2009 under the auspices of NSAI. This BESS voluntary group carried out very good work and were responsible for the implementation of the Emergency Lighting Certification Scheme. The Chairman of the...
The possibilities of PAT

The possibilities of PAT

Portable Appliance Testing – or PAT Testing as it’s more commonly known – is now part of Irish legislation, providing a new opportunity for electricians in the Republic of Ireland. All businesses must carry out Portable Appliance Testing (PAT) on all...
Emissivity in the Infrared

Emissivity in the Infrared

Effects of Emissivity Thermal imaging cameras detect and measure the sum of infrared energy over a range of wavelengths determined by the sensitivity of the camera’s detector. Thermal imagers cannot discriminate energy at 7µm from energy at 14µm the way the human eye...
Emissivity Coefficients of some common Materials

Emissivity Coefficients of some common Materials

The radiation heat transfer emissivity coefficient of some common materials as aluminum, brass, glass and many more The emissivity coefficient – ε – indicates the radiation of heat from a ‘grey body’ according the Stefan-Boltzmann Law, compared...
Reflected Temperature Correction

Reflected Temperature Correction

Today’s topic: when we enter the emissivity correction value into the thermal imager, we are, in essence, telling it what percentage of the total energy it sees is being emitted by the surface. If that surface, like most we look at, is also opaque (meaning we can’t...
A basic guide to thermography

A basic guide to thermography

Thermography Thermography is a method of inspecting electrical and mechanical equipment by obtaining heat distribution pictures. This inspection method is based on the fact that most components in a system show an increase in temperature when malfunctioning. The...
Electrical cable reels dangers

Electrical cable reels dangers

Following a number of recent incidents, including electrocutions, where electric cable reels were involved, the HSA wishes to warn people of the dangers that could arise from the misuse or abuse of electric cable reels. The danger arises principally from overloading,...
Thermographic Surveys

Thermographic Surveys

Infrared Thermographic technology is a non-intrusive method of measuring temperature. All surveys are carried out while the plant/machinery is on load. Electrical problems highlighted during surveys (normally carried out on MCC/distribution panels/transformers)...
