Gartek
Engineering has extensive experience in electrical power distribution
with special emphasis in substation design. Our experience
encompasses design in low, medium, and high voltages to 230
kV. our experience in this field is derived from contracts
with Florida Power & Light Co., International Power Systems,
Inc., Asea Brown-Boveri, and others. Design in this specialized
field requires familiarity with relay protection schemes,
expertise in the preparation of short circuit and coordination
studies, and knowledge of state of the art equipment and devices
currently available in the market. Intimacy with protection
philosophies and redundancy requirements are paramount if
designs are to carry the desired reliability.
White
Street Substation, Key West, Florida
New Substation consisting of, two 25/33.3/41.67 kVA, 69-13.8
kV transformers; 6-feeder Metalclad Switchgear: two underground
feeders; two capacitor banks; ground grid study and ground
grid design; relay coordination study; relay settings; 69
kV underground getaway design including cable selection, schedule
of materials, calculations and field erection drawings. 13.8
kV underground main feed from transformer to switchgear including
cable selection, schedule of materials, conduit schedule and
calculations. All field remote cable schedules for AC and
DC circuits as well as current transformer connections. Site
lighting and temporary 69 kV and 13.8 kV circuits.

- 8.32/4.16 kV Substation.
Coconut
Grove Substation, Coconut Grove, Florida
Removal of 4 kV section at substation and approximately 2
miles of 4kV feeders. Installed new 13.8 kV section at substation,
35,000 kVA transformer, and two feeders dedicated to the use
of the METRORAIL Rapid Transit System.
Juno
Beach Substation, Juno Beach, Florida
Increased transformer capacity by adding a third 30 MVA transformer,
added 13.8 kV feeder, bur-tie breaker and transformer low-side
motor operated vacuum load break switches. Upgraded relay
protection scheme to differential protection, extended 138
kV bus, added a third 138 kV pull-off structure and relocated
one 138 kV pull-off.
St.
Augustine Substation, St. Augustine, Florida
