Energy harvesting from non-invasive current sense transformer
I have a non-invasive current sense transformer (SCT-013-030) which according to its [datasheet](https://www.digikey.gr/htmldatasheets/production/1824515/0/0/1/SCT013-030-Specification.pdf) it is voltage output type. I want to harvest energy and supply a wireless sensor that consumes 5-6 uA current average. The most common approach is a rectifier on the output of the transformer. But I'm a little concern that this is not going to work on this specific type of sensor cause it will produce 1V AC at 30A load. Which means unless the current is at the maximum, the rectifiers will not conduct. The question is, whether my theory is correct or there's actual a way to harvest energy from this sensor that I'm not aware of.
