Re: Fault current available at 66th & Thurston Road Monitoring Station
Dear Chuck:
The Proposed service has the following characteristics:
Primary feed: Opal Circuit out of Mt. Vernon Substation at 12.47 kV
Service: 120/240
Transformer: 50 kVA
1.4 % impedance .
Transformer#1505
Given these criteria, the expected fault current is 14,881 Amps.
These values may increase based on future system changes to either the Springfield
Utility Board electric systems or the regional high voltage power system.
rpared by,
Tony Mot
Engineering Technician
