AC voltage meter

So, I'm trying to quantify the power consumption of one of my AC devices. My measurements, however, are not what I expected and/ or varying more than I expected.

I don't think I can fit a transformer in my lineup of devices. What do you think I could be using to get more accurate measurements?

Thank. Greatly appreciate your feedback.
What kind of power you need to measure - active (real), reactive, apparent ? Easiest and most reliable way is to use solution that is used in E-Meters (AFE) - it can fullfill most reqiuirements. Hope 0.1% accuracy is OK (if you can calibrate it once).
