how to ttr a single phase transformer?

To test the turns ratio (TTR) of a single-phase transformer, use a TTR meter. First, ensure the transformer is de-energized and safely isolated. Connect the primary winding to the meter’s primary terminals and the secondary winding to the secondary terminals. Apply a known voltage to the primary side and measure the output voltage on the secondary side. The turns ratio is calculated by dividing the primary voltage by the secondary voltage. Ensure all safety protocols are followed during testing.
