OBITUARY: JAMES TERENCE (TERRY) De LACY TERRY De LACY, a well-known figure in the lighting world, passed away in Ireland on 13 May 2018 after a 10 year battle with cancer, which he fought with great positivity, determination, faith and courage. He is survived by his daughters Patricia De Lacy, Caylin De Lacy, Chalise Du Plessis and his grandson Keegan De Lacy. A lighting engineer with a critical eye for quality of luminaires and lamps and their influence on per- formance and reliability in use, De Lacy served on the South African National Standards Authority Commit- tee working group for LEDs and previously held the position of President of Institute of Lighting Engineers of South Africa. His LinkedIn bio described him perfectly; Terry De Lacy meeting Prince Charles on his visit to the Our Ladys Hospice & Care Services, Harolds Cross, Dublin, where Terry was an outpatient at the time due to ongoing cancer treatment in 2017.

Apart from being an Elected Fellow of the Institute of Lighting Engineers of South Africa (1997) and of the Illumination Engineering Society of South Af- rica (2004) he also lectured part-time at the Durban Teknikon in Illumination Engineering and authored numerous technical papers on lighting. In his spare time, De Lacy enjoyed fly fishing, camping, swimming, cricket, rugby, golf, hiking, photography and DIY.

“A lateral thinker, I thrive on challenge. Customer satisfaction and cost and energy saving as well as aesthetically pleasing installations are always the desired outcome. Continuously striving to be abreast of the latest technology, I am thus able to provide eco-friendly, cost effective solutions.” De Lacy worked in South Africa for GEC, Beka, Osram, Genwest Industries and The Lighting Consultants, amongst others, before moving to Thorn Lighting in Ireland in 2007, where his excellent people management, organisational and leadership skills, balanced with an affable personality and a fierce sense of loyalty and commitment, won him many friends in the industry.

DEMAND MORE FROM LOW VOLTAGE SYSTEMS

C ompanies involved in the exploration, extraction and processing of natural re- sources look for the smartest, safest, most cost-effective way to run their operations. Oppor- tunities to lower capital costs and operating ex- penses are often buried within a site’s low voltage (LV) power distribution networks. Schneider Electric has an innovative high breaking capacity for the Compact NSX range of moulded case circuit breakers (MCCBs), offering users more from their LV infrastructure and a cost- effective alternative to fuses over the long term. Smart alternative to high-power fuses The high breaking capacity of the Compact NSX circuit breakers will withstand demanding fault conditions, staying reliably in service after three faults. After a fault is cleared, remote control re- closing functionality puts circuits back into op- eration quickly, enabling maximum operational continuity. Discrimination and co-ordination will isolate faults, to avoid system-wide outages. Over the long term, this reduces the cost impacts of downtime and avoids the labour and parts costs associated with fuse replacement, giving users a total-cost-of-ownership advantage. Critical,highdemandpowerdistributionsystems, operating at 440/480 V or lower, need protection against extreme short-circuit fault currents. Such faults occur in systems with multiple paralleled power sources or large numbers of motor loads. The higher breaking capacity of the Compact NSX range can be used to provide better protection and higher continuity. Best-in-class protection • Compact NSX remains the highest-rated breaking capacity in its class of 100 kA for 500-690 V systems. • Industry-leading breaking capacity of 200 kA at 440 V. • Type II coordination for motor applications. • Extended breaking capacity available across complete Compact NSX range from 100 to 630 A. • Extended breaking capacity comes in the same space-saving frame sizes as other Com- pact NSX models. Class-leading performance enables the entire Compact NSX range to meet the requirements of applications that once mandated costlier, bulkier protection devices. Users can realise significant cost savings by safely running higher power densi- ties on LV platforms or benefitting from the higher energy efficiency and reduced space requirements of a 690 V system.
