10. WORK HISTORYWORK HISTORY
Project management of annual electrical
maintenance. This included substation
transformer, breaker & Switchgear testing.
The transformer testing included TTR, Insulation
and Oil Analysis.
The breaker test consisted of testing the trip unit
with secondary current injection, Phase to Phase
and to Ground Insulation, DLRO test of contacts
and connections and hi-pot vacuum bottle test.
Clean/Inspect Motor Control Centers
Checking all terminal connections in MCC buckets

11. WORK HISTORYWORK HISTORY
Upgrade of Protective Relays on 23 feeder
breakers, 3 tie breakers and 6 main breakers
while the system was in service.
Removal of 126 electromechanical protective
relays
Installation of 33 SEL protective relays
Removal of over 3600 wires in the protective
relay circuits & rewire using approximately 1500
new SIS wires to the electronic relays.
Each system control circuit was function tested to
the output of the trip and close coil circuits

12. WORK HISTORYWORK HISTORY
Performed Power Studies which included fault
contributions, protective device coordination and
Arc Flash hazard analysis
Use of SKM and ETAP software
Provided recommendation of solutions for the
reduction of arc flash levels at all voltage levels
Reduced arc flash calories from over 5000 to less
than 40.

13. WORK HISTORYWORK HISTORY
Project management for the installation of a new
substation
Installation of a Square D Power Dry II
substation
The transformer is 12,470 primary voltage and
480 secondary voltage
The feeder breaker unit has a 4000 amp main
breaker and four 1600 amp feeder breakers

14. A complete refurbishment and redesign of a
161kV substation yard
All of the existing 161kV insulators will be
replaced with new
The three existing three OCB’s will be removed
and replaced with six SF6 GCB’s
All of the old vertical break switches in the yard
will be replaced
The new yard design will reduce the number of
switches from 16 to 10 with a design for switches
to be exercised regularly without power
interruption.
