Napetie v kablovom rozvode UPC


Recommended Posts

Pri prekablovavani (kable pod listy) mi pri rozpajani zrazu prsty zabrneli. Meranim som zistil ze na tieneni je potencial cca 110 V. UPC digital, analog, internet, TV, settopbox, video, DVD, tuner, UPC signal roboceny na 4 cez zosilovac. Odkial sa to tam vzalo? Je niekde chyba, problem?

To je normalni, zpusobuje to vyrovnavaci proud zemniho potencialu tekouci mezi kabelovou siti a uzemenim u tebe doma, nekdy muze zpusobovat brum ve zvuku, nebo poruchy obrazu, pak je potreba ho odfiltrovat galvanickym oddelovacem, ale v prevazne vetsine pripadu to nastesti neni potreba.

 

A tu koncovou zasuvku tam urcite dej.

kabel UPC - rozdelenie signalu tv a data - modem - router - aktivny rozbocovac - toto je vsetko na jednom mieste, odtial taham kabel k tv a tuneru na opacnom konci izby, z rozbocovaca idem potom este na dalsie miesta, ak by tam bola krabica tak musim tahat na kazde miesto 2 kable . . . jeden tv a druhy radio . . . teda na vsetky nie, ale skoro na vsetky.
