POWER OUTAGE -OCTOBER 26,1997,REPORT
Director Matzke reviewed the sequence of events (beginning at 0843
on 10/26/97 through 1445 on 11/7/97),explaining there were three
faults and the outage involved two dispatch centers;Western Area
Power Administration (WAPA)and Platte River Power Authority
(PRPA).Mr.Matzke explained what occurred during the outage
referring to a diagram of the substations.Contributing factors to
the outage were:
•Age of equipment (35 years)
•Previous Electrical Fault on Main Switch #1
•Dust,contamination in switchgear
•Moisture in building
•Two of the three electrical faults observed occurred in
the only areas where the bus was not insulated.
It has taken less than two weeks to recover from the outage.
Preventative measures include:
•All 12kV bus and insulation was inspected,cleaned where
appropriate,and high voltage tested before the station
was returned to service.New weather-stripping was
applied to all panels removed during the inspection
process.Transformer back up relays and bus relays were
reset to increase likelihood of local tripping of the
appropriate circuit switcher in the event of a bus fault.
•Foam insulation was applied around the perimeter of the
building at ground level early this year to limit
infiltration in the building.This should also limit
entrance of dust and contaminants into the building.
•Estimates for sealing the roof of the building and
outdoor bus enclosures will be obtained.
•Step up testing and maintenance:
•Infra Red Scanning
•Oil Testing of Transformers
•High Voltage Testing of Bus and Breakers
•Evaluate replacing main switches with external pad mount
breakers.
•Replace substation (recommended for 2005 in the Long
Range Plan)
The Committee expressed interest in considering the option of
accelerating the schedule to replace the substation and
options/financial information will be presented at the December
