Electrical 250 X 122

The Engineers Ireland Electrical division is for engineers with an interest in electricity, electronics, and electromagnetics.

The division has links with other professional associations and organisations such as the Conseil International des Grand Reseaux Electriques (CIGRÉ) and NSAI’s Electro-technical committee under the direction of the CRU.

Energy monitor can find electrical failures before they happen

A new system devised by researchers at MIT can monitor the behaviour of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an imminent failure. When tested on a coast guard cutter, the system pinpointed a motor with burnt-out wiring that could have led to a serious onboard fire. The new sensor, whose readings can be monitored on an easy-to-use graphic display called a NILM (non-intrusive load ...

Purple bacteria 'batteries' turn sewage into clean energy

You've flushed something valuable down the toilet today. Organic compounds in household sewage and industrial wastewater are a rich potential source of energy, bioplastics and even proteins for animal feed - but with no efficient extraction method, treatment plants discard them as contaminants. Now researchers have found an environmentally-friendly and cost-effective solution. Published in 'Frontiers in Energy Research', their study is the first to show that purple phototrophic ...

Engineering team designs technology for smart materials

University of Virginia mechanical engineers and materials scientists, in collaboration with materials scientists at Penn State, the University of Maryland and the National Institute of Standards and Technology, have invented a 'switching effect' for thermal conductivity and mechanical properties that can be incorporated into the fabrication of materials including textiles and garments. Using heat transport principles combined with a biopolymer inspired by squid ring teeth, the team ...

How to score an A+ grade for excellent CHP specification

When in the midst of the exam season, teachers were always fond of saying the following: 'fail to prepare, prepare to fail'. Fast-forward to working life and the same truth applies, particularly to specifying combined heat and power (CHP). Here, if you fail to plan and do your homework properly you're likely to get a 'U' for 'unfit' grade CHP system, rather than being regarded as an 'A' level performer. The effectiveness of a CHP system depends in large part on the preparation time and ...

A power system in transition

The electricity system is changing in ways that make it desirable for grid operators to engage with residential customers for the first time. EirGrid is responsible for ensuring the day to-day operational security of the power system. Through our innovation programme, we research, develop and deploy innovative solutions that help us manage it. One of our main aims of the innovation team is to create flexibility to adapt to the changing nature of the electricity industry. Many of the ...

Why electrical engineering is fundamental in green buildings

Buildings have become more energy efficient thanks to construction practices that emerged in the last few decades, writes Jahnavi Sajip @NewYorkEngineers. Older buildings were designed assuming open windows, and heating systems were oversized as a result; on the other hand, modern construction practices focus on insulation and air-tightness to reduce heating and cooling loads. However, there is still a key challenge to overcome: space heating and hot water systems are very dependent on ...
