Re: Symmetrical Fault Current for FPL
Facilities
Dear Mr.Cardonw
You recently requested symmetrical fault current information at the FPL facilities at several
locations on the main campus of South Miami Hospital. As Such, the information is as follows,
2-1500 kVA transformers in parallel, with a secondary voltage of 2776480 V in the main Vault. The
symmetrical fault current at this facility is 54,000 Amps. This is calculated with an actual
impedance of 4.8% on each of the transformers. This assumes an infinite bus at the vault.
The 1500 kVA transformer in the same vault has a syninietrical fault current of 31,000 Amps at
277/480 V, This also 2S%urnes an infinite bus at the transformer with an actual impedance of 4,9%.
The 1000 kVA transformer in the North Tower vault has a symmetrical fault current of 22,000
Amps. The same assumptions apply with an actual impedance rating of 4.89%
The 500 kVA transformer in the East Tower vault has a symmetrical fault current of 27,757
symmetrical amperes at 120/208 V.
The FPL equipment currently serving or planned to Serve Your facility may change over time as a
result of any number of factors, including but riot limited to transformer replacements due to load
growth, electrical grid changes or emergencies, As a result, although we are providing You with
this information for the sole purpose of assisting you in the completion of your Study, you should
not design, install or operate Your system in reliance upon any expectation that the specific size
and type of equipment currently in place will remain so, If and when the size and type of the
equipment changes, Our employees are not always in a position to immediately notify Customers,
This calculated symmetrical fault current is not intended for use as the basis for motor starting
calculations and does not include consideration for any motor contribution Or fault current
asymmetry,
ANYONE USING OR RELYING ON THIS INFORMATION DOES SO AT THEIR OWN RISK, AND
FLORIDA POWER & LIGHT COMPANY DISCLAIMS ANY LIABILITY FOR EITHER
NEGLIGENCE OR WARRANTY ARISING THERE FROM.
If You have any ClUestions or concerns please call me at (305) 552-2507,
Sincergly,
