Confirm the 380 V to 44 V conversion duty

Provide phase, frequency, connection, neutral and earthing requirements and confirm whether 44 V is required at no load or rated load. The nominal ratio alone does not establish regulation or terminal configuration.

Review 300 kVA output current and load

Define continuous demand, starting current, power factor, duty cycle and nonlinear content. The low secondary voltage can result in high current, so bus, cable, terminals and protection must be coordinated from model-specific data.

Document winding and cooling details

The database lists Copper Winding but not conductor section, winding arrangement, insulation, cooling, temperature rise or enclosure. Request the construction schedule and thermal data for the offered unit.

Coordinate the high-current interface

Provide cable or bus arrangement, terminal orientation, short-circuit conditions, upstream and downstream protection, clearances and installation constraints. Obtain impedance, dimensions, weight and terminal drawings.

Set test and acceptance requirements

Request losses, impedance, temperature rise and applicable dielectric or functional tests. IEC is a database reference only; compliance depends on the named standard edition, model and report scope.

Frequently Asked Questions

The production record lists 380 V to 44 V. Phase, frequency, connection, regulation and final terminal data must be confirmed in the quoted schedule.

A 44 V secondary at 300 kVA can involve high current. Use the model-specific phase, current, terminals and impedance to size buswork, cables and protection.

The current record does not confirm phase. State the required phase and connection and verify them on the offered nameplate and drawings.

They are not established by the current record. Confirm thermal design, ventilation, temperature rise, enclosure and clearances for the installation.

Request the electrical and current schedule, nameplate, GA and terminal drawings, impedance, losses, thermal data, test plan and model-matched reports.
