Core Principles: How an Electrical Generator Produces Electricity

Electromagnetic Induction at the Heart of Every Unit

All modern generators, from compact inverters to megawatt industrial systems, leverage electromagnetic induction. When a conductor (such as copper windings) moves through a magnetic field, an electric current is induced. Generators exploit this principle by mechanically rotating a rotor inside a stator assembly.

Primary Components and Their Functions

  • Rotor (Armature): The rotating element that creates a moving magnetic field.
  • Stator: Stationary coils of wire surrounding the rotor; this is where electricity is generated.
  • Prime Mover: An engine—diesel, natural gas, propane, or gasoline—that turns the rotor.
  • Voltage Regulator: Maintains steady output voltage as load conditions vary.
  • Cooling and Exhaust Systems: Prevent overheating and remove combustion by-products.
  • Lubrication System: Reduces friction and extends engine life.
  • Automatic Transfer Switch (ATS): Detects grid failure and triggers the generator to start, then safely transfers load.

HEP’s generator technicians in Louisville inspect, test, and calibrate each component to keep the entire system operating in harmony.
