🔍 Key Concepts

• Paralleled transformers and why matching characteristics is important • The meaning of polarity markings on transformer terminals • Effects of incorrect connections on voltage, phase, and circulating currents

💭 Think About

• Which of these steps directly affects whether the new transformer will share load correctly with the existing one? • Which options deal with actual electrical relationships (voltage and phase) between the two transformers, rather than temporary conditions like static or residual magnetism? • If two transformers in parallel do not have the same polarity and phase relationship, what can happen to current flow between them even with no external load connected?

✅ Before You Answer

• Verify which option ensures correct polarity and phase relationship with the existing transformer. • Check which actions are standard practice when putting transformers in parallel in power systems texts, not just on ships. • Confirm which options are about long-term correct operation (load sharing, no circulating currents) versus short-lived effects like static charge.
