WebMay 9, 2014 · Regarding the parallel and series connection of CT's: Secondary of the CT can be considered as CURRENT SOURCE! Connecting two CT'S in parallel means two current sources outputs connected to the load, which means the result is the algebraic summation of the two secondaries of the CT's i.e: If CT1 = 300/5 A. CT2 = 300/5 A. WebDec 18, 2024 · In Australia, where we specify CT's to IEC / AS 60044.1, typical CT classes would be 10P20 2.5VA for protection and class 0.5M 2.5VA for metering. So the combined CT class would be "10P20 & 0.5M 2.5 VA". You can still connect a kWh meter to a protection-class CT (with no metering class), however the accuracy of the kWh meter will …
