Electric Generator vs Genset: Key Differences
What is the difference between an electric generator and a generator set? Both devices have the same objective: to provide electrical power. This is why the two concepts are often confused.
Technically, an electric generator is a component designed to convert mechanical energy (motion) into electrical energy. In contrast, a generator set is a complete system that integrates an electric generator and an internal combustion engine, allowing it to function autonomously.
Defining the Concepts
Understanding the fundamental concepts of electric generators and generator sets is essential for correctly using both terms.
Electric Generator
An electric generator is a device that transforms mechanical energy into electrical energy. This transformation occurs through a rotating system where a rotor generates a magnetic field that induces a current in the stator.
Electric generators are commonly used in power plants to generate electricity that can be stored and consumed later. They require an external power source, such as diesel engines (which would form a generator set) or steam turbines, to provide the necessary mechanical energy.
Generator set
A generator set combines an internal combustion engine with an electric generator (also known as an alternator) in a single unit. This equipment is self-sufficient and designed to generate electricity in emergency situations or locations without access to the electrical grid.
When activated, the engine burns fuel to produce mechanical energy, which the alternator then converts into electrical power, ensuring an immediate and reliable energy supply.
Why Is There Confusion Between the Terms?
In everyday use, many people think of an electric generator as a compact unit, such as portable models used in homes or small businesses during power outages. These devices, typically with a capacity of up to 10 kVA, are accessible and practical, ideal for powering household appliances or basic tools.
However, this concept is incorrect. These small units are not just electric generators but small generator sets, as they integrate both an internal combustion engine and an electric generator in a single self-contained unit.
On the other hand, the term generator set is often associated with large industrial electric generators, like those manufactured by Genesal Energy. These units are designed for large-scale projects, with power outputs ranging from 10 kVA to several MVA, and are essential in industrial, healthcare, energy, and critical infrastructure sectors.
This misuse of terminology can lead to confusion when selecting the right equipment or understanding how it functions.
How to Choose the Right Equipment
The choice between an electric generator (or rather, a small generator set) and an industrial generator set depends on the intended use:
- Small domestic or commercial applications: Low-power portable units (up to 10 kVA) are usually the best option. Although they are commonly called electric generators, they are technically compact generator sets.
- Industrial or large-scale applications: In these cases, it is necessary to opt for industrial generator sets with higher power capacities, capable of ensuring a continuous and reliable power supply, like those in our catalogue.
Although “electric generator” and “generator set” are often used interchangeably in everyday language, it is important to understand their technical differences and applications.
In essence, every generator set contains an electric generator, but not all electric generators are complete generator sets.
