Emergency Repairs

Spinella Contracting, Inc. was called on a Monday, after close of business, to assess damage that had been caused to a medium voltage (12,470V) substation within a midrise corporate complex due to a roof leak. Upon troubleshooting and testing, Spinella Contracting, Inc. determined that the roof leak caused a catastrophic failure of this substation’s 2,500 kVA transformer. After weighing the options available to restore power expeditiously, Spinella determined the most cost effective solution was to field measure the existing buss configuration and send this information to an out of state vendor to fabricate the required bussing to mate with a readily available (out of state) 2,500 kVA transformer.  The transformer and bussing were delivered to the site by Wednesday morning. Spinella Contracting, Inc. removed the failed 10,000 pound transformer from the existing substation that day. The following day the new 10,000 pound core and coil assembly was rigged into the substation.  Friday morning the custom fabricated bussing was bolted in to place and all connections were made to the new components.  Upon the completion of acceptance testing, the new substation was re-energized and the midrise building’s power was permanently restored by 4:00 pm.
