I have a simple LC notch filter for a power lines communication application.
I want to test my filters impedance change while carrying a high current, upto about 15A. In my application this current will be at 50Hz, but I'm happy enough to test at DC. My notch frequency is around 10MHz
I have an impedance analyzer (Agilent 4294A). However this can only provide a bias current of 100mA. MY 15A will be provided by a DC power supply (at a pretty low voltage) but I am very nervous about my impedance analyzer. Can someone suggest a set up to measure my filter impedance while carrying 15A without breaking my analyzer.
Simply, I consider DC blocking caps... but would they have to be huge and would they ruin my filter impeance measurement??
