HOW THIS STUFF WORKSWhat is a Transformer?
• A transformer is an electrical device that transfers
electrical energy between two or more circuits.
• Transformers are used to increase or decrease the alternating
voltages.
• Each transformer has a specific capacity and a overload of
that capacity could cause power outages.

MODELING THE POWER NETWORK
• In our power service area we have 2,000+ transformers
• One of the first things we had to do was calculate the peak
meter consumption for meter.
• Then by using ArcGIS to model our the power system and Model
Builder we have created a process that allows us to trace the power
network data. Then identify all the transformers that are over 140%
capacity.
