| description abstract | Description of Driving Event: During the removal of power to a transformer prior to it being serviced, an accidental 2400 Volt line to ground short circuit was created resulting in minor injury to a technician and minor hardware damage. The major contributing factor to this mishap was the use of a drawing that was not adequately checked after additions and changes had been made to the system. The secondary factor was that the technician did not test the voltage on the line side of the potential transformer compartment to verify that the bus was in fact de-energized. | |
