y otras áreas interiores y exteriores en
Menlo Park, Nueva Jersey, fueron iluminadas por un total de 53 luces (gráfico  2). A comienzos de 1881, había
aproximadamente 500 luces de Edison
en funcionamiento en Menlo Park, en
un área de 1 milla por 0.5 millas alrededor del laboratorio y las obras de Edison y utilizaba casi 8 millas de alambre.
En 1880, Edison ya estaba planeando
una versión comercial de un sistema de
distribución de energía eléctrica. El 9
de agosto de 1880, presentó una solicitud de patente, "Sistema de iluminación
eléctrica", la cual fue emitida el 22 de
marzo de 1881 con el número de patente estadounidense 239,147.
Esta invención se refiere a un
sistema de tendido de conductores que transportan la corriente
desde una estación central o
fuente de energía eléctrica a través de un sistema de iluminación
o traslación eléctrica.
Esta es la primera vez que se adopta
el término ferroviario "estación central" para designar una estación central de energía eléctrica. La estación
central Holborn Viaduct de corta vida
de Edison en Londres comenzó a funcionar el 24 de abril de 1882 con una
capacidad de 2,200 luces con una intensidad luminosa de 16 candelas. La
famosa estación de Pearl Street y el sistema de distribución de Edison Electric
Illuminating Co. de Nueva York en el
bajo Manhattan comenzaron a funcionar el 4 de septiembre de 1882. En un
solo mes, la empresa tenía 59 clientes
con 1,284 luces, y al 1.° de diciembre
de 1883, 513 clientes con 10,297 luces,
según un boletín de la Edison Electric
Light Company. (Esta fue la primera
septiembre/octubre 2019

En el siglo XIX no existían transformadores prácticos para la conversión
descendente de CC de alta tensión. En
los Estados Unidos y en muchos otros
países, la transmisión de alta tensión

Power System Reliability
A new module to analyze the reliability of electrical
power distribution systems and calculate the
expected availability of loads.

· Auto-import

reliability data or specify failure
rate, downtime, and cost.

· One-click

analysis of the entire system or a
specific load branch.

· Identify weak points and factor cost of power
interruption in future design.

El sistema de CA de Lucien
Gaulard y John Dixon Gibbs

empresa eléctrica de Edison, constituida en Nueva York el 15 de noviembre
de 1878. Financiaba los experimentos
de luz eléctrica de Edison y controlaba
sus patentes). En 1887, Edison tenía 103
estaciones centrales de CC en los Estados Unidos, con 311.400 luces en uso.
