FernandoaugElectricista: THREATENED FROM HEAVEN

LOS ELECTRICISTAS

Que hacemos los electricistas

Mucha gente no valora el trabajo de los electricistas. Generalmente, cuando alguien adquiere una propiedad, hace visitas a todos los sitios existentes, asiste a eventos, teatros, hoteles, restaurantes, etc., todo parece que funcionara a la perfección. Pero ¿Quién esta detrás de todo este sistema de cosas que alumbran y funcionan? Obviamente los electricistas, ese grupo de personas anónimas que día a día se esfuerzan para que todos puedan disfrutar de las instalaciones eléctricas.

Pero no lo hacen como por arte de magia, los electricistas tienen que prepararse muy bien en el día a día, bien sea aprendiendo de sus maestros o jefes de obra, estudiando y haciendo cursos para nivelarse con los grandes y pequeños cambios que nos dan los avances tecnológicos y los nuevos diseños de los distintos sistemas de cosas que se hacen visibles en el presente.

Son varios los distintos caminos por los que tiene que andar el electricista por que existen varias áreas de especialización. Así vemos al electricista en la construcción, en la industria, en el comercio, como instalador, reparador de electrodomésticos, etc.

Su afán de progreso y superación por adquirir más conocimientos y experiencia lo lleva a cubrir cualquier necesidad y requerimiento. Su meta es brindar calidad y buen servicio.

Para ser electricista hay que formarse. Es común ver a una persona subirse en un poste a realizar una conexión de una acometida eléctrica o desarmar un electrodoméstico sin estar preparado para ello.

En Venezuela existen varias instituciones donde se imparten cursos de electricidad, una de ellas son las Escuelas Técnicas Industriales ahora llamadas Escuelas Técnicas Robinsonianas. Así lo decía ese gran maestro Simón Rodríguez:

“Si la instrucción se proporcionara a todos….entre los que vemos con desdén, hay muchísimos que serian mejores que nosotros, si hubieran tenido escuelas”

THREATENED FROM HEAVEN

THE MOST DANGEROUS NATURAL PHENOMENON THAT IS PRESENT WHEN A STORM IS GENERALLY IS THE Atmospheric discharge THAT IS PRODUCED AMONG CLOUDS. LARGE AMOUNTS OF ENERGY ARE RELEASED IN JUST A FEW FRACTIONS OF TIME WITH CONSEQUENCES THAT CAN RESULT FATAL AGAINST HUMAN LIVES, ANIMALS AND MATERIAL PROPERTIES AS ELECTRICAL STATIONS, DISTRIBUTION LINES AND ELECTRIC BUILDINGS IN GENERAL, WHEN THIS CONVERTS IN RAY AND DISCHARGE FROM THE CLOUD TOWARD THE EARTH.

MANY TIMES ARE PRESENTED IN SIMULTANEOUS GROUPS, THAT CROSS THE SKY OF BRANCHED AND CONTINUOUS MANNER PRODUCING AN IMMENSE SOUND. SOUND AND LUMINOSITY PRODUCED REACHES VARIOUS KILOMETERS IN THE DISTANCE.

SOUND AND FLASH OF LIGHT PRODUCED BY A LIGHT TRAVEL AT DIFFERENT SPEEDS WHICH ALLOWS TO CALCULATE THE DISTANCE BETWEEN THE POINT OF ORIGIN AND THE FALLING POINT

ELECTRICAL ENGINEERING INSTITUTES AND WORLDWIDE SAFETY TIPS HAVE DEVELOPED GUIDELINES AND DETAILED METHODS TO PREVENT DAMAGE CAUSED BY THE ELECTRICAL BALLS THAT CAUSE THESE RAYS ON THE ELECTRICAL EQUIPMENT.

SO WE HAVE, BETWEEN OTHER:

-INTERNATIONAL IEC 62305-3

-SENCAMER

-NTC 4552-2

-DIN EN62305

-IRAM 2426

-UN 21186

-MKS N.84 810

-NP 4426

-I 20

-34 1391 STN

-N.84.810 JUICE

-IEEE-1584

THERE ARE METHODS FOR CONDUCTING CALCULATIONS TO CONTROL THE RISK FOR ELECTRIC BALLS WHICH ASSUMES THE COLLECTION OF A FIELD DATA SERIES OF THE ELECTRICAL SYSTEM AND IN PARTICULAR OF THE DIFFERENT FACILITIES AND TO REVISE THE ELECTRICAL FLOOR UPDATES IN SPECIATYPE WHERE THESE ARE CHANNELED.LIZE THE UNIFILAR DIAGRAMS OF THE SYSTEM THAT MAINLY IN SYSTEMS THAT INCLUDE OWN GENERATION OR EMERGENCY AND INCLUDE ENGINES OF GREAT SIZE. THIS FIELD DATA SURVEY MUST INCLUDE AS MINIMUM SIZE, TYPE, LENGTH AND QUANTITY OF CABLES AND POWER AND STRENGTH BARS AND THE ROUTE

ALL TRANSFORMERS, CAPACITY, IMPEDANCE, RELAY RATIO AND ASSOCIATED PROTECTIVE EQUIPMENT MUST ALSO BE TAKEN.

THERE ARE PROGRAMS CREATED BY SPECIALISTS OF ENGINEERING IN VARIOUS FORMATS AND SOFTWARE BUT THE MOST COMMON IS THE EXCEL CALCULATION SHEET. IN THIS PUBLICATION NO CALCULATION DEMONSTRATIONS OF THESE RISK CONTROL SYSTEMS WILL BE MADE, ONLY SOME STEPS NEEDED TO BE COMPLETED.

THE MODULE OPERANDI OF THE POWER SYSTEM AND THE CHARGE TYPES THAT DEPEND ON IT MUST BE WELL DEFINED AS AN IMPORTANT DATA THAT THE CALCULATION SYSTEMS REQUIRE.

THE CALCULATIONS OF SHORTCUTS OR CALCULATIONS OF THE DIFFERENT TYPES OF FAILURE ARE NECESSARY TO DETERMINE THEM, AS WELL AS ELECTRICAL BALL FAILURE CURRENTS BASED ON SYSTEM VOLTAGES OCCURRING IN OPEN OR CLOSED SYSTEMS.

THE BEHAVIOR OF THE PROTECTIONS AT THE TIME OF THE ELECTRIC ARC OCCURRENCE AND ITS DURATION IN TIME, CONSIDERING THE MAXIMUM AND MINIMUM TIMES OF COMPENSATION OF THE FUSES AND CIRCUIT BREAKERS.

THE ANALYSIS AND COMPLETE CALCULATIONS OF THESE RISKS FOR ARCS PRODUCED BY RAYS IS NECESSARY TO APPLY ACCORDING TO EACH OF THE STANDARDS DEVELOPED BY THE EXPERTS OF EACH COUNTRY WITH ELABORATED STANDARDS. PARTICULARLY,
THE IEEE 1584 STANDARDS ARE RECOMMENDED:
