World Metrology Day 2014
World Metrology Day 2014 was observed here with a collaboration between the Saint Lucia Bureau of Standards and the Ministry of Physical Development and Sustainable Development. The collaboration involved a presentation to the public on the popular talk show 90 Minutes on the national radio station, Radio Saint Lucia hosted by Shelton Daniel.
The department heads of Metrology and Compliance of the SLBS Mr. Anselm Gittens and Mr. Hubert Raynolds were joined by Sustainable Development Officer Mr. Ken Aldonza for the event. The programme focused on this year’s theme “Measurements and the Global Energy Challenge" It was an opportunity to promote the work of the agencies in particular as it relates to the measurement of sources of energy such as fuel and electricity through the use of fuel dispensers and electrical energy meters respectively.
The SLBS maintains a series of services with impact on the sector, to include; pattern approval of measuring instruments, verification of measuring instruments, measurement disputes investigation, metrication and the testing of compact fluorescent lamps (CFLs) and refrigerators.
The discussion generated tremendous public interest with members of the general public calling in to the show to seek clarification and make recommendations related to a range of issues in the energy sector. Among these was the recommendation for the nominal single-phase voltage of 240 V to be changed to 230V and the justification for this.
This is a perennial issue for persons with interest in the sector as Saint Lucia’s voltage is supposed to be set at 240V however many electrical appliances available from local merchants are rated for 220V or 230V. While consumers are less concerned with what’s to be done, there has been some interest in the supply voltage being set at a point to allow for the use of household electrical appliances rated for 220V. The main issue here is that operating an appliance rated at 220V from a 240V (to 249 V)voltage supply could reduce the life span of that electrical appliance leading to frequent repair and replacement costs for the consumer. Related to the voltage compatibility of appliances, have been complaints about the high cost of electricity associated with the use of inefficient step-down transformers for 110 V appliances which are available for purchase in the country.
Other issues related to the energy efficiency of CFL’s and safety were highlighted as general issues of interest.
