Series
12-Pulse Transformer
Low-harmonic · drive isolation · phase-shift
Three-phase 12-pulse transformer with two output windings phase-shifted by 30° (delta + wye) for use with 12-pulse rectifier drives. Reduces harmonic injection back into the supply by ~85% versus a 6-pulse drive. Critical for harmonic-sensitive sites and IEEE 519 compliance.
Key Features
- ▸30° phase-shift (Δ + Y)
