    Losses in Toroidal CTs

    Thanks Guys! I guess we need to improve the art of manufacturing :) For example we found out that wrapping the CT with the soft silicone tape helps to reduce pressure and thus improve CT performance. However, it doen't work 100%. BTW, I've looked at the Pressductor and found out that "The...

    Losses in Toroidal CTs

    Thanks for answers! The pressure is applied by molding the CT in the epoxy. Once the CT is molded in the epoxy, the losses are increasing. For example,on 500:1 CT, we are loosing 5-10mA on the secondary (with 20A on the primary) after molding. I've simulated the same phenomena pressure...

    Losses in Toroidal CTs

    I am performing testing on toroidal CTs and have hard time undestanading the results. WOuld like to hear your thoughts. Test set up is extremaly simple. Constant current generator is applying the primary current through the CT, and I am measuring voltage across resistor that is connected to the...
