SCOTT T TRANSFORMER
28 KVA, P/N 19508N
Scott T Transformers offer two single-phase outputs and not one single-phase output.
Scott T Transformers cannot be used to create only one single-phase output.
Specifications:
- Scott T Transformer, 28 KVA, 60 Hz, P/N 19508N
- Primary Input (H1, H2, H3): 480 VAC, 34 Amps
- MAIN Output (X1, X2): 208 VAC, 67 Amps, 14 KVA
- TEASER Output (Y1, Y2): 208 VAC, 67 Amps, 14 KVA
- Copper windings, copper bus bars are 1/8″ x 5/8″ with one hole
- MAIN and TEASER are 90 degrees out of phase
- Jumper will be provided
- Indoor enclosure, 42″H x 32″W x 22″D
- Estimated weight: 600 lbs.

Test # 1 of P/N 19508N
Test Set Up (MAIN and TEASER are not connected in series)
Test Results:
- Input Voltage V (A, B) = 286 VAC
- Input Voltage V (A, C) = 287 VAC
- Input Voltage V (B, C) = 284 VAC
- Line A Current = 2.67 Amps
- Line B Current = 2.64 Amps
- Line A Current = 2.53 Amps
- Output MAIN (X1, X2) = 124 VAC, 4.97 Amps
- Output TEASER (Y1, Y2) = 123 VAC, 4.73 Amps
Conclusions:
- When MAIN and TEASER are not connected in series, input currents are balance.
Test # 2 of P/N 19508N
Test Set Up (MAIN and TEASER are connected in series)
Test Results:
- Line A Current = 4.15 Amps
- Line B Current = 1.0 Amps
- Line A Current = 3.0 Amps
- Output MAIN (X1, X2) = 106 VAC
- Output TEASER (Y1, Y2) = 106 VAC
- V (X1, Y2) = 150 VAC
Conclusions:
- V (MAIN) and V (TEASER) = V (Sum) / √2
- Input currents are not balanced. I (H1) = I (H2) + I (H3) approximately
