Downstream: what depends on it
Power transformer requires input Grain-oriented electrical steel2 evidenceEstablished relation
Power transformer depends on Grain-oriented electrical steel.
Mechanism
Transformer cores are stacked laminations of grain-oriented electrical steel chosen for low core loss. Amorphous alloy cores are a partial alternative in distribution units; there is no drop-in core material for large power transformers.
