You have close to 90 degrees phase shift between voltage and current, your circuit tuned to resonance,
so most energy going back and forth between power supply and circuit.
You could say that power is 0 if waveform would be symmetrical, but there are small asymmetry (I marked with green color). So it is close to 0.

BTW current and voltage shapes are sine, it is not ferroresonance
Thanks. I'm sorry there is something wrong with my scope or new probes or user error. I was confused by these measurements and now I cannot get the channels in phase with a resistive load. Please ignore my last schematics and scope pictures.
Thanks,
Sandy
Edit...
High voltage probes were shifting phase measurements 90 degrees. Ha too good to be true. Is this a common occurrence?
