We are preparing a product, with a transmitter module installed, to an Asian country for in-country testing. We are instructed to have the module installed in the end product during EN 300 328 transmitter testing (conducted method). The product is powered by 230V AC. Our engineers tell me if I do not isolate the ground, I will damage the receiver.
Hi Grace:
In selecting your isolation transformer, one thing to watch out for is that many "isolation transformers" actually carry the ground path all the way through.
I learned this several years ago when I bought a pair of Tripp-Lite isolation transformers for use in my lab. I had to re-wire them to obtain the galvanic isolation that I was seeking.
My impression is that many of the "isolation" transformers that are available on the market are intended for *noise* isolation, not *safety* isolation. The distinction is not always clear in the product literature.
