Electrical Theory 101
Electrical Theory 101 Current: Amps – number of electrons moving per second – Flow
Voltage: kilo-Volts – energy level of moving electrons – Pressure
Power (Demand): kilo-Watts – Energy Delivered per second – Rate
Energy (Consumption): kilo-Watt-Hours – total energy delivered over a time period – The contents of the bucket
Electrical Arcing
What about Lightening?
Arrestors – Overvoltage Protection
Equipment Protection Lightning can create sustained electrical arcs within the electrical distribution network
Electrical Arcs are dangerous, and will quickly damage the system
We apply a layered safety system comprised of breakers, reclosers and fuses and arrestors.
