0:45 - How to determine Wye primary connections
1:21 - How to determine Delta primary connections
2:19 - Example 1: The primary voltage on the nameplate is 19900/34500 Y, with a Phase-to-Neutral voltage of 19900 is a WYE connection
2:34 - Example 2: The primary voltage on the nameplate is 4160/7200 Y, with a Phase-to-phase voltage of 7200 is a DELTA connection
2:50 - Example 3: The primary voltage on the nameplate is 12000, with a Phase-to-phase voltage of 12000 is a DELTA connection
3:05 - Example 4: The primary voltage on the nameplate is 12000/20800 GrdY, with a Phase-to-Neutral voltage of 12000 is a WYE connection
