Hi
Im trying to find a test equipment that can be used for the EN 60601-2-2 §201.8.8.3.103 ACTIVE ACCESSORY HF dielectric strength. Test data is; 7.2 kV, Crest factor 5.4 6.6, Frequency 300 500kHz Normally I use a signal generator with modulation (to control crest factor) a AR HF amplifier and a HV transformer. But the only transformers I can get is only rated 100kHz so I need to drive them very hard to get a 300kHz signal through, and thereby I have now blown 8 transformers over the last 2 years. A good HV HF transformer could also be an option, but they dont seem to be standard product and a local transformer manufacturer could not make one for me. (the primary impedance shall be higher than normal) Where can I get a tester or a transformer?
