Original poster: Mddeming-at-aol-dot-com Hi All, FWIW, old Triplett analog multimeters often have max AC & DC rated inputs of 5-6 kV. They have been going on eBay for 10-$15 USD. These might be useful for testing at up to 25%-40% power on TCs, depending on your transformer. Although they're considered "hand-held" meters, don't hold it in your hand while testing Matt D.
