Knowledge topic
Electrical Parameters
Definitions and selection effects of capacity, voltage ratio, frequency, vector group, impedance, insulation level and tap range.
Ratings
Rated capacity and voltage define the basic electrical duty but do not fully define the transformer design.
System compatibility
Frequency, phase, vector group, grounding and impedance affect system integration and parallel operation.
Voltage regulation
OCTC and OLTC arrangements provide different methods of adjusting transformer ratio.
Knowledge explains the decision. Project data sets the design.
Send the rated capacity, voltage ratio, application, site conditions and applicable standards for engineering review.
