🔍 Key Concepts

• Three-phase delta connection relationship between line current and phase current • Difference between line values (line-to-line) and phase values (inside each winding) in three-phase systems • How current splits or combines at a delta junction

💭 Think About

• In a delta connection, is the line current the same as the phase current, or is it larger/smaller? Why? • At each corner of the delta, how many phase currents come together to form the line current, and at what angle are they separated electrically? • Which operations (multiply/divide by 3 or by √3) usually relate line and phase quantities for current vs. voltage in delta and wye systems?

✅ Before You Answer

• Be clear on whether the question is asking for line current or phase current • Recall: in a delta system, one of the electrical quantities (voltage or current) is the same for line and phase, and the other differs by √3 • Eliminate any answers that would make line current smaller than phase current if you know in a delta whether line current should be larger or smaller than phase current
