Has anybody used these matt-e products for EV charging points?

Is this brand any good ? 

The supply source is a three phase T-N-C-S system. The load on the three phase distribution board is never going to be fully balanced so the options are to either to install earthing rods (electrode) or use one of these devices to avoid hammering rods to be compliant.

Just wondered if anyone had any experience with the brand.

Any other ideas also welcomed.

Regards,

J

    I see exactly where John is coming from. If the three phases were reasonably balanced, there wouldn't be a problem. I have looked at the same issue for myself and the loads are only sufficiently balanced when charging. That would be fine if the EVCP disconnected on completion of charging.

    As I understand it, the physics allows comparison between the actual neutral current and the expected one. (Or is that voltage? ? )

    I am still waiting for the market to mature and would also be interested to see other opinions.
