There is no reason he should compromise safety. It all depends on his project specifications. Is it only to write a few code lines to fabricate the maths, or is it also to design a proper hardware? We don't know up to now. Many professional power meters get their supply from mains and aren't isolated from mains! They use optos to provide an isolated data link, if at all. Anyway, if he uses transformers he still needs to take care for isolation and safety issues! Especially if he tries to fabricate them by himself... Kai |
