After the Technical failure registered in the Las Américas International Airport (Aila), Free newspaper talked with the specialist Miguel RosarioMSC, to understand what this type of breakdown means and how it affects the electricity supply.
P. What does He mean collapse of the Cell Set –sectioning of medium voltage in the terminals And how does the electricity supply affect?
R. A sectioning cellit is a equipment that is used to isolate electrical circuits and elements of protection of electrical installations, such as Disyntors. It is used in different voltage levelslow voltage (120 – 480 volts), medium voltage (7,200 – 12,470 volts) and high voltage (34,500, 69,000, 138,000, 230,000, 345,000, etc.).
A fault in a sectionit can mean the total opening of a circuit and if there is no Alternate system that can supply energy, becomes a Total blackout.
This failure It is rare if the electrical system is designed and operated correctly. This type of failuredepending on the circuit configuration, it can take more than five hours to solve it in the best case, as long as the spare parts are available in the fault.
P. How much serious or complex is this type of failure compared to others Electrical breakdowns common?
R. Sand the element that failed (sectioning) was common to Power circuits (including support), all energy feeding circuits are disabled at the same time.
P. Why the unavailability of the backup circuit further complicated the situation and what role this circuit plays in the system stability?
R. Depending on the electrical power capacity they handle (medium voltage) They can be acquired locally.
P. How much complicated is fix either replace A set Cell -selecting of medium voltage?
R. Replace A sectioner can take five Ten hours.
