Boa noite.
Eu não percebi bem o que é o produto, até porque parece haver 3 diferentes (?), mas a solução parece ser à superfície, e não enterrada.

A solução é enterrada. Nos links que enviei está bem claro. Além do mais segundo as FAQs, parece que com o passar do tempo (pelas demonstrações in situ) a impedância tende a reduzir.rainbow Escreveu: 02 jan 2022, 20:26Boa noite.

Esta seria uma solução face à vareta.
Eu em Portugal nunca vi, mas no meu ponto de vista parece ser uma solução e prática recorrente no Canadá e UK.

Re: ConduDisc vs Ground Rod - Eletrodo de terra
Parece me uma solução interessante para projetos muito específicos, fica a dúvida se tem aprovação aqui na Europa

Re: ConduDisc vs Ground Rod - Eletrodo de terra
Respostas às minhas perguntas:
1. I am from Portugal and we do not use this kind of condudisc but only earthing rods and copper cable. Amoung Earthing Services (UK) there is another distributor in Europe?
a. At this time, Earthing Services is our go to distributor and engineering support group in the UK. SAE can offer direct support and also ship direct from our plant in Canada as we offer very good lead times. SAE has a broad background from power utility to telecom (data centers, towers, switch centers) to broadcast as well as more specialized services like needle manufacturing grounding/NASA quiet room grounding/Walmart campus grounding etc.
2. What is moreless the cost of the condudisc?
a. 80 USD for our ConduDisc Flex – where your crews can attach the necessary conductor at time of install
b. ~150 USD for our ConduDisc Pro – this one comes with conductor connected and molded into the disc. Pricing varies with size and length of conductor required.
3. I do not remembre to see in IEC or IEEE standards this kind (round shape) of earthing electrodes.
a. Typically grounding codes and standards specify the requirements for GPR/step and touch/R-value be met in order for a system to be considered safe. The ConduDisc is a tool designed to accomplish this with a longer lifespan and simpler installation process than traditional methods.
b. US/Canada codes and standards define grounding electrode requirements by minimum thickness and surface area of the metallic component. ConduDisc is designed and manufactured to meet this needs.
c. If you have any specific local codes or standards you refer to and can share, we would be happy to review and comment to ensure we meet your needs.
4. Is condudisc used for lightining protection? Also I do not remember that IEC 62305 standard recommend this kind of round shape.
a. This is application specific. In terms of utility pole surge arresters, a ConduDisc will provide a low impedance, low resistance path to ground to ensure arresters function as designed and the equipment on the pole is adequately protected.
b. In terms of large telecom or transmission towers, we approach lightning protection with the use of engineered grounding electrodes. These may be 6” drilled holes, with depths reaching 500 feet. These may also be enhanced horizontal electrodes. Each of these solutions are completed using another product of ours – Conducrete or ConduFlow. These backfill products are designed to increase the surface area of the conductor you are installing, and thus increases the surface area connection between the electrode and the earth – improving impedance characteristics for lightning protection events.
c. In data/switch centers, we approach grounding using the single point methodology and PANI configured gorunding bars. Our engineered systems have proven to be the best when it comes to high value asset protection.
