Peña, Robín A.Gómez, Víctor A.Hernández, César2012-04-122012-04-1220101794-4449http://hdl.handle.net/10567/158This article shows the design and the construction of a prototype to measure quality indicators in electric energy services, measuring the discountinuity in the service by using, as a base, a voltage sensor which generates logic states in the output, so the algorythm designed in high level C language and implemented in the PIC18F2550 micro-controller can register the events that take place every three months. The prototype consists, mainly, in a liquid crystal screen, a micro-controller, an external memory and a real time clock. This measurer has a low running cost, a wide memory to tregister the events and a great precission to measure the duration of the interruptions.esEnergía eléctricaElectricidad - MedicionesServicios públicos - Energía eléctricaCorporación Universitaria LasallistaIndicador de frecuencia equivalente de las interrupciones del servicio (FES)Indicador de duración equivalente de las interrupciones del servicio (DES)Diseño y construcción de un prototipo de medición de los indicadores de calidad del servicio de energía eléctrica (des y fes) para usuario residencialDesign and construction of a measuring prototype for energy service´s quality indicators(des and fes) for residential consumersDesenho e construção de um protótipo de medição dos indicadores de qualidade do serviço de energia elétrica (DES e FES) para usuário residencialArticle
