Calculator preliminar

Transformer calculator

Estimate primary and secondary current at full load and at the expected operating load level.

Assumptions used by this calculator

  • This is a loading and current estimator only; it does not replace thermal, impedance, or fault-duty review.
  • Expected load percent is used to scale operating current from transformer full-load current.
  • Final design still needs protection, voltage regulation, impedance, cooling, and installation checks.

Available load

195 kVA

Estimated working load at the configured operating percentage.

Primary current

13.12 A

Full-load primary current at transformer rated kVA.

Secondary current

360.84 A

Full-load secondary current at transformer rated kVA.

Expected primary current

10.23 A

Primary current at the configured expected load percentage.

Expected secondary current

281.46 A

Secondary current at the configured expected load percentage.
