  • Leakage Current Measurement Basics | Fluke

    6 mins readMay 09, 2013Any imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA. For example, taking a measurement on a 240 V ac circuit with all loads disconnected might result in a value of 0.02 A (20 mA) leakage.

    So the output transformer doesn’t get the credit or blame for that “saturated” sound. The actual source is in the push-pull power tube plate circuit reacting/saturating to the changing impedance it sees in the primary coil of the output transformer as its flux density changes with the changing frequencies and fluctuating power coming into it.
