What is the meaning of 32Yd1 on a transformer?
This is 3 Nos Two Winding Transformers put together to form of Three Phase transformer, HV is Star Connected & LV is Delta Connected in the LV phase is leading by 30 Degree with respect to HV phase
What is the meaning of DYN 11 on a transformer nameplate?
What does Dd0, Dyn11, YNd5 etc. mean?First symbol/symbols, capital letters: HV winding connection.Second symbol/symbols, small letters: LV winding connection.Third symbol, number: Phase displacement expressed as the clock hour number.Winding connection designationsHigh Voltage Always capital lettersDelta - DStar - SInterconnected star - ZNeutral brought out - NLow voltage Always small lettersDelta - dStar - sInterconnected star - zNeutral brought out - nPhase displacementPhase rotation is always anti-clockwise. (international adopted convention)Use the hour indicator as the indicating phase displacement angle. Because there are 12 hours on a clock, and a circle consists out of 360°, each hour represents 30°.Thus 1 = 30°, 2 = 60°, 3 = 90°, 6 = 180° and 12 = 0° or 360°.The minute hand is set on 12 o'clock and replaces the line to neutral voltage (sometimes imaginary) of the HV winding. This position is always the reference point.Because rotation is anti-clockwise, 1 = 30° lagging (LV lags HV with 30°)and 11 = 330° lagging or 30° leading (LV leads HV with 30°)To summarise:Dd0Delta connected HV winding, delta connected LV winding, no phase shift between HV and LV.Dyn11Delta connected HV winding, star connected LV winding with neutral brought out, LV is leading HV with 30°YNd5Star connected HV winding with neutral brought out, delta connected LV winding, LV lags HV with 150°
What is the difference between Dyn-11 and Ynd-11?
Winding connection designations High Voltage Always capital letters Delta - D Star - S Interconnected star - Z Neutral brought out - N Low voltage Always small letters Delta - d Star - s Interconnected star - z Neutral brought out - n Phase displacement Phase rotation is always anti-clockwise. (international adopted convention) Use the hour indicator as the indicating phase displacement angle. Because there are 12 hours on a clock, and a circle consists out of 360°, each hour represents 30°. Thus 1 = 30°, 2 = 60°, 3 = 90°, 6 = 180° and 12 = 0° or 360°. The minute hand is set on 12 o'clock and replaces the line to neutral voltage (sometimes imaginary) of the HV winding. This position is always the reference point. Because rotation is anti-clockwise, 1 = 30° lagging (LV lags HV with 30°)and 11 = 330° lagging or 30° leading (LV leads HV with 30°) To summarise: Dd0 Delta connected HV winding, delta connected LV winding, no phase shift between HV and LV. Dyn11 Delta connected HV winding, star connected LV winding with neutral brought out, LV is leading HV with 30° YNd5 Star connected HV winding with neutral brought out, delta connected LV winding, LV lags HV with 150° " So there is no specification of Dy11.. it will be Dyn11 "
