FYI
From: Barnett, Robert [mailto:[email protected]] Sent: Tuesday, 17 July 2012 11:04 AM To: Owen Byrnes Subject: HiPOT testing Thanks Owen, I did indeed receive your HiPOT email. My 10 cents worth on this topic: HiPOT voltages are DC aren't they? Any detrimental effect on a foetus would be through capacitive coupling via mum's body. At zero frequency, there's zero coupling. Even if the high voltage is AC, I would say that its transmission power is tiny and incapable of penetrating the skin level, let alone any deeper layers. Finally, there's frequency. If the high voltage is AC and powerful (which is completely unnecessary for insulation testing), it is not likely to be at radio frequency and once again can't penetrate the superficial tissue. I would therefore not lose any sleep over an expectant mother using a HiPOT. This is just my opinion and is not backed up (or refuted) by a review of the literature. Regards, Robert.
