Prevención de corrosión galvánica

[PEPE]

¿Conoce alguien este conector electrico que parece ser avisa cuando hay riesgo de invasión de la "corrosión galvánica" ?

I've had a Marinico GalvanAlert "Shore Power Corrosion Detector" for a year, but I only got to use it briefly at first. That was time enough to see how handy it is to have a power tester right in hand as you hook up your shore cable. At minimum, a green LED will tell you that a dock receptacle is live. Plus you'll get a red LED if the polarity is reversed, and two yellow levels of warning about stray current in the ground line, i.e. the stuff that can eat metal parts off your boat's bottom. By now I've used the GalvanAlert, which costs about $140, a fair bit at a dock and even in a shed, and have seen how its steady monitoring can reveal shore power mysteries...

Podría ser interesante

Gracias

Pero parece interesante, a ver si algun cofrade sabe algo.

¿Nadie sabe nada de este dispositivo aparentemente tan interesante?

2 diodos en oposición con 1 par de leds en paralelo no valen 140$.

Medir la corriente de fuga a tierra es útil, pero no evita la corrosión galvánica.
