This like is from Cartoon Lover8902. High Voltage electricty comes from both AC (alturnitve current) and DC (direct current), and it could be dangerous!
House Current PowerEdit
From a house gets some of the 240VAC for HVAC (Heating Ventalation and Air Conditioning) only for the condenser units for cooling, and also 120VAC goes to the rest of the house, powering a TV, an Oven, a Microwave oven, etc.
Commercial and Industreal PowerEdit
These ones are using 277/480VAC power, by a Three Phase Transformer, on a pad mount or pole mounted. Inside of the electical room, there is a small transformer which converts it to 240/120VAC.
A substation is a power source for step down power for Distrubution Lines, from the Transmission lines.
The transmission lines go from a substation to distribute power.
These lines have a iron pole, and two grounding lines.
Distribution lines are wooden or iron poles that have insulators, and components like for example: Transformer, or a Capacitor Bank.
