Hello friends: I found a 87T application (7UT6 Relay) with a ring scheme in the high voltage side of the power autotransformer (dual breaker line with different CTs Rel). The matching CT is connected in autotransformer mode in the 1500/5 CT circuit. Please, in which direction secondary current flows and its magnitud per branches?? See attached files.
Some guidelines, please¡¡
Thank you so much¡¡¡
