3 Phase Transformer Size Chart

3 Phase Transformer Size Chart - The inputs are the transformer kva (power), and the voltage in the primary and secondary windings. Web sizing three phase transformers always size based on load volts and load amps! This tool will allow you calculate the kva that you need. A transformer with a 100 va rating, for instance, can handle 100 volts at one ampere (amp) of current. Web fuse link ratings recommended in these tables will carry the full load of the transformer continuously and will open in five minutes when the transformer load is approximately three times full load. Enter the primary and secondary transformer voltages. Select the appropriate kva size from the selection charts listed on this page or by using the single phase or three phase sizing formula listed below.

How To Determine Transformer Kva Ratings.

Kva = volts x amps x 1.73 1000 (1.73 due to phase shift of 120 degrees between phases) (1.73 = square root of 3) Web three phase transformers, full load amperes (flc) kva: Enter the primary and secondary transformer voltages. Click on the calculate button to obtain the results.

This Tool Will Allow You Calculate The Kva That You Need.

Smaller or larger fuse link ratings may be used to give the desired correlation of protection and continuity of service. Transformer load expressed in amperes: Web steps to calculate the transformer size: This chart is meant to offer recommendations only and is not an acceptable substitute for an electrical engineer.

There Are Three Different Types:

This transformer calculator will calculate kva, current (amps), and voltage. Learn more about doe 2016 energy efficient transformers by schneider electric. Table 1 or the following formula can be used to determine the proper kva size for the required transformer. If you need a device that converts from different voltages so it can power another device, then a transformer will fulfill that role perfectly.
