Electrical Generators

Electrical generators supply extra, backup, or essential power for applications such as power outages, remote areas, data centers, construction sites, and critical environments.

Whether you need to preserve food at home, keep systems running at work, or operate an outdoor festival, Trinity Electrical Services installs, repairs, and maintains the generator power you need.

Trinity Electrical for All Types of Generator Power

Trinity Electrical Services installs, repairs, and maintains all generator classifications – AC, DC or AC/DC – for homes, businesses, organizations, and outdoor or public purposes.

AC generators convert mechanical energy into electrical energy in the form of alternating-current electricity or electromotive force (EMF), which is an energy transfer to an electric circuit per unit of charge measured in volts. Aided by a moving magnet, an AC generator’s current moves through a fixed coil in the opposite direction. AC generators can be single-phase, synchronous, three-phase or induction units.

DC generators convert mechanical energy into direct current (DC) electricity according to the principles of EMF. The unfixed coil moves in a fixed field and the current flows with it. DC generators can be shunt-wound (e.g. for battery charging), series-wound (e.g. for street lights), self-excited (e.g. for lab testing), and compound-wound (most other applications).

An AC/DC generator allows you to select either AC or DC power for the greatest versatility.

Because of their independent power production, generators can:

  • Provide power for most networks across cities
  • Power up construction sites before the main power is on
  • Supply backup power for homes & businesses
  • Supply power for cars, aircraft, ships, and trains
  • Provide ranges of voltage output, such as for labs
  • Reduce consumption of fuel

For those who really like mechanical knowledge, an electrical generator’s components include:

  • Frame (structure)
  • Engine (energy source)
  • Alternator (production of output from the input)
  • Fuel System (keep the generator running)
  • Voltage Regulator (manage the voltage output)
  • Cooling System (regulate building heat levels)
  • Lubrication System (ensure smooth, durable operation)
  • Exhaust System (release waste gases that are created)
  • Charger (keep the system battery charged)
  • Main Control (panel with interface for operation)

Tom H. – Aurora, IL

"The technicians at Trinity services were extremely professional. It was a pleasure to open up our home to them. My wife and I were extremely impressed with how neat and clean they worked. A lot of contractors just don't care, but I could tell that Trinity was not one of those contractors."

Bruce – Naperville, IL

"I met Josiah last week when he came out to 310 S Rosedale in Aurora to consult with my clients about the house they are buying. I was very impressed by both his knowledge and wiliness to answer questions. Far too many in the trades are not quite so customer centric. In any case, it is my pleasure to recommend your company to other agents and to my own clients in the future."
