Yes, it should ring out in both cases when you set a meter on ring/ohm and measure phase to phase or phase to ground/neutral on a transformer. Here's why

Ring/Ohm Setting:

When you set your multimeter to the ring/ohm setting, it sends a small electrical current through the circuit you are testing. If the circuit is complete, the current will flow and cause the meter to "ring" or make a sound.

Transformer Windings

In a transformer, the primary and secondary windings are connected together at the neutral point. This creates a complete electrical path between the phases and neutral.

Measurement



Phase to Phase

When you measure phase to phase, you are testing the continuity of the circuit between two phases. Since the windings are connected, the current will flow through the primary winding, cross the neutral point, and return through the secondary winding. This completes the circuit, and the meter will ring.

Phase to Ground/Neutral

When you measure phase to ground/neutral, you are testing the continuity between a phase and the neutral point. Since the neutral point is connected to the windings, the current will flow through the primary or secondary winding, cross the neutral point, and return to the meter. This also completes the circuit, and the meter will ring.

Conclusion:

Therefore, when you set your meter to the ring/ohm setting and measure phase to phase or phase to ground/neutral on a transformer, you should hear the meter ring because the electrical circuit is complete through the connected windings. Flag for review
