Understanding Transformer Testing

[@ChrisSmith-tc4df]

As a practical matter, I would have described the primary as the driven winding as secondaries are typically wound atop it for the best coupling.

[@pauldenisowski]

Yes, agreed, but it's a lot harder to illustrate :) Thanks!

Current in one coil does not induce a voltage in another coil that is magnetically coupled unless the current is varying in time. It's not enough to simply have 2 coils to be magnetically coupled.

Sir if i short secondary side and measures in primary side by LCR meter then it is leakage inductance of primary side OR overall leakage inductance referred to primary side??

Great explanation 👍🏼👍🏼👍🏼

Большое спасибо!

Emang real non-Z, but we're not real function. Lol, great explanation 👍

[@pauldenisowski]

Thanks! :)

Why is there loss of 14v from hand wound toroid transformer output with separate winds on core not overlapping. The frequency of primary was matched to source AC, the primary and secondary windings are in same direction and entire ring core is covered with wire , but 2 separate sides. I thought the core under Primary caused induction into separate secondary windings. Desparate.
