No, not at all so simple, unless the nst is powering a simple resistive
load. But when it's powering a capacitive load, particularly a LTR
capacitive load, things change dramatically. My unmodified 15/60 routinely
pulls over 20A from the wall, this WITH PFC caps. I believe the operation
of the shunts ceases when ferroresonant behavior begins. This is a Good
Thing, and another reason to use LTR caps.
To the original question - use an analog meter.
