[Petr Simek]

Dobry den

narazil jsem na tyhle proudova trafa -

   http://en.yhdc.com/product/SCT010T-D-376.html
   https://www.poweruc.pl/products/split-core-current-transformer-sct010t-d-rated-input-5a-50a

a leze z toho DC napeti na sekundaru. Uvadeji accuracy 2% ale jak
toho dosahnou kdyz je tam usmernovac ? Ten prece potrebuje nejake
napeti na otevreni, Takze pro proudy do deseti procent rozsahu by
to nic moc davat nemelo .

Nevite jakou to ma linearitu ? Zadna prevodni charakteristika
tam neni.
