3.6.6. Testing a Three Phase Transformer Using Auto Detect Mode
The ATRT-03 provides a convenient Auto Detect mode that can automatically detect 130
specific vector groups for different transformer types defined by ANSI, CEI/IEC, and Australian
standards. The transformer configurations supported are listed in Appendix B, C, and D. The
ATRT-03 can detect the vector diagrams for Delta-Delta, Wye-Wye, Delta-Wye, and Wye-Delta
transformer types. Follow the steps below to test a three phase transformer using the auto
detect mode:
a.
Start from the “START-UP” menu:
Press the
