High Voltage Diesel Generators vs. Low Voltage: Key Differences ...

When it comes to choosing the right diesel generator set for industrial, commercial, or residential use, it's vital to understand the differences between high voltage and low voltage generator sets. Both types of generator sets play a vital role in providing backup or primary power, but there are some differences in their uses and applications. In this article, AGG will break down the key differences between high voltage diesel generator sets and low voltage diesel generator sets to help you make an informed decision.

What Are High Voltage and Low Voltage Diesel Generators?

Before going any further into the differences, it is important to recognize the meaning of "high voltage" and "low voltage" in the context of a diesel generator set.

  • High Voltage Diesel Generator Sets: These generator sets are designed to operate at voltage levels typically higher than 1,000 volts. They are typically used for large-scale power generation, such as industrial plants, manufacturing facilities and large commercial operations. High voltage generator sets are often used to power large numbers of machines or critical electrical loads.
  • Low Voltage Diesel Generator Sets: These generator sets operate at voltage levels typically below 1,000 volts. Low voltage diesel generator sets are typically used for small applications such as standby power for small businesses, residential buildings and commercial organizations.

Low-voltage diesel generator sets, which operate at standard voltages, are often used for smaller, more localized requirements. These generator sets are ideally suited to provide standby power for smaller applications such as small to medium sized businesses, residences or events and construction sites.

2. Design and Size

High-voltage diesel generator sets are designed to handle high power outputs, often in larger, more cumbersome designs. They require more robust infrastructure and safety features such as step-down transformers, specialized switchgear and protective devices to handle high voltage safely.

On the other hand, low-voltage generator sets tend to be more compact and easier to transport. Their smaller size makes them suitable for a variety of environments, from home backup power to small-scale commercial operations. Compared to high-voltage generator sets, these small sizes are easy to move around, providing convenience for businesses that need a flexible power source.

3. Cost and Efficiency

There is a large cost difference between high-voltage and low-voltage diesel generator sets. High-voltage generator sets are usually more expensive because they are complex in design and require additional equipment such as transformers and protection systems. They also require more maintenance and attention due to their size, power output and use in more critical applications. Low voltage diesel generators, by contrast, are less expensive both in terms of initial investment and ongoing maintenance costs.

5. Maintenance Requirements

High-voltage generator sets typically require more complex maintenance and regular inspections. Considering the magnitude of the power they generate, any problem with a high-voltage system can have greater consequences than with a small generator set. Technicians require specialized training and equipment to maintain and repair high-voltage installations.

Low-voltage diesel generator sets are simple in design and low in maintenance complexity. However, regular inspection of the engine, fuel system and other components is still necessary to ensure effective operation.

Benefits of Using a Three-Phase High Voltage Diesel Generator

Benefits of Using a Three-Phase High Voltage Diesel Generator

If you’re trying to save money but looking for a powerful, high voltage diesel generator, then a used three-phase generator is the best choice for you. Three-phase high voltage diesel generators are ideal for data centers, large commercial buildings, or industrial centers. This article from Woodstock Power discusses the benefits of using a three-phase high voltage diesel generator.

Power

If you’re looking for a high voltage diesel generator, you’re looking for power. With that in mind, three-phase generators produce exceptionally higher voltage than single-phase generators. Common voltages for single-phase generators are 120, 240 and 120/240, but typically the voltage for a three-phase unit is 480. Other three-phase industrial generator voltages include:

  • 208
  • 120/208
  • 277/480
  • 240
  • 600 (primarily used in Canada)

High-voltage generators like these provide a power factor of 0.8. Also, they are primarily used for powering electrical industrial motors with higher horsepower and other heavy-duty applications.

Cost

Now, you might be thinking that power like that comes at a pretty penny, but buying a used three-phase high voltage diesel generator from Woodstock Power can give you all the bang for much less buck. In fact, you could save up to 70% off of the cost of a new one!

If you’re concerned that sacrificing dollars means sacrificing quality, do not worry. We purchase working, brand-name high-voltage generators ranging from 25kW-kW, perform any necessary restoration/repair work, and test them to ensure they’re in peak operating condition. Any generator that does not meet our high standards is rejected.

Efficiency

Far and away the greatest benefit of purchasing a three-phase high voltage diesel generator is its efficiency. Consider how it contrasts with single-phase generators…

  • More efficient use of conductors – with the same peak voltage between conductors and the same current in each conductor, 3-phase generators deliver three times more power with one and a half times the copper compared to single-phase generators.
  • Always producing mechanical power – instantaneous power is never zero in a 3-phase generator, so no start winding is necessary and they have a smaller frame for the same horsepower.
