HEP’s technicians ensure that each generator not only starts promptly but also produces clean, stable electricity free of surges or spikes that could damage sensitive electronics.

How Electric Generators Work

Basic Principles of Power Generation

At its core, a generator converts mechanical energy into electrical energy through electromagnetic induction:

1. A prime mover—typically an internal combustion engine—turns a crankshaft.
2. The crankshaft spins a rotor encased in a stator with tightly wound copper coils.
3. As the rotor’s magnetic field sweeps past the stator windings, it induces an alternating current (AC).
4. The generated voltage is regulated by an Automatic Voltage Regulator (AVR) to maintain steady output.

With correct maintenance, this seemingly simple process produces consistent voltage and frequency suitable for all types of loads, from heavy compressors to delicate laboratory analyzers.

Generator Classifications

Standby Generators

Installed permanently outside a building, standby units engage automatically when utility power falls below preset thresholds. They offer:

• Rapid automatic transfer within seconds
• Larger fuel reservoirs (natural gas, propane, or diesel)
• Weather-proof enclosures and sound attenuation

Portable Generators

Portable models are ideal for construction sites, small shops, and outdoor events. Mounted on wheels, they are:

• Easy to move to different work areas
• Powered by gasoline, diesel, or propane
• Started manually or with electric start options

PTO (Power Take-Off) Generators

Common on farms in Loudon’s rural outskirts, PTO generators are:

• Driven by a tractor’s PTO shaft
• Cost-effective since they share existing diesel powerplants
• Scalable, matching tractor horsepower to generator kVA ratings

Fuel Options and Their Characteristics

• Natural Gas: Requires pipeline access, offers long runtimes without refueling.
• Propane (LPG): Stored in onsite tanks, burns cleaner than diesel, minimal varnish formation in carburetors.
• Diesel: Higher energy density, preferred for heavy loads, excellent cold-weather ignition with proper additives.
• Bi-Fuel Systems: Combine natural gas and diesel to extend runtime and reduce emissions.

Transfer Switch Technology

An Automatic Transfer Switch (ATS) senses utility voltage, commands the generator to start, and transfers load once voltage stabilizes. HEP technicians test ATS operation during every service visit, confirming correct time delays, sequence of operation, and mechanical integrity.
