Electricity has become more than just a human necessity; our very existence was recalibrated around it the moment it was discovered. We can no longer function or be productive without it. Having backup power for those hurricanes, snowstorms, and everything that might disconnect us from the grid or damage the grid, therefore, gives an added sense of security.
There are different types of generators to choose from. Finding the appropriate one tailored to suit your needs is a life-changing decision and should not be taken lightly.
You need to understand the qualities of the different types of generators and their differences before settling on what you are looking for. The 3-phase generator, which this article is about, is a powerful energy source with many features and a wide range of applications.
A 3-phase generator has a type of circuit that provides three alternating currents of the same magnitude and equal frequency. These currents are mutually offset in time by a third of the wave period, meaning they are 120% out of phase with each other. This ensures they are constantly at different phases of their cycles, and power generation is consistent and safe.
Electric currents travel in wave cycles, and the electric power falls to zero three times in every cycle of 360%. Having three currents of similar frequencies with a difference of 120% between them guarantees that there is no point the power will be at zero.
The delay between phases facilitates consistency in the transfer of power to balance a linear load. This is why 3-phase generators are considered an improvement to the single-phase generator, whose circuit only provides one current.
Advantages of 3 Phase Portable Generators
They Have a Large Loading Capacity
3-phase generators have a higher power output than their single-phase counterparts because they produce three AC power voltage waves in one cycle. Their typical voltage output is usually around 480 Volts.
Unlike single-phase generators, they can be used to power large equipment reserved for light equipment like domestic and slighter commercial establishments. A 3-phase generator can easily power your entire home in case of an electrical outage.
Versatile Application Opportunities
They are adaptable to stepping up and stepping down using transformers. This means you can adjust the output to fit your equipment rating by either increasing or reducing the output voltage.
Consequently, they have a vast load range capable of powering everything from light domestic equipment to more powerful industrial equipment. A neutral wire enables the 3-phase system to maintain a higher voltage while supporting single-phase appliances with lower voltage ratings.
Provision of Clean Power
The stable and consistent power generation guarantees it is free from voltage fluctuations, spikes, and drops. The 3-phase wires back each other up such that in case a fault occurs in one of them, the other two will still supply power.
This makes them safe to use with sensitive equipment like TVs, laptops, and desktop PCs without damaging them.
Power Generation Efficiency
The 3-phase set up supports efficiency in a number of ways:
- Using transformers to reduce the current results in efficiency as the step-up feature allows the transmission link sizes to be thinner.
- The transmission of electricity at a high voltage means less impedance and reduced energy loss to the environment during transmission. There is also less winding of coils in a 3-phase setup, requiring less conductive material (copper or aluminum). This curbs energy loss further.
- Distributing the load over 3 phases or waves ensures there is less draw on each of the waves. As a result, the generator operates at the optimal level and is not strained by the load.
Compact and Light Units
3 phase portable generators have the uncanny ability to pack a large amount of power in smaller and lighter units due to a combination of attributes. We have already established they require less conducive material, less than what a single-phase generator will need for the same power output.
They Are Pocket Friendly
They are cheaper to construct than single-phase generators with similar ratings. Running the 3 phases together saves on wiring costs. All three phases share one neutral wire to complete the circuit, and the windings are used more efficiently. They guarantee a bang for your buck.
Instantaneous Power
Their 3 phases provide sufficient torque to start the motors, so they don’t require starters like the single-phase generators. This torque is consistent, so is the power, which allows the generator to operate with fewer vibrations, reducing noise production and saving energy.
Little Maintenance Required
A 3 phase generator hardly requires the rigorous maintenance we have become accustomed to when dealing with generators. The distribution of the load over three phases ensures there is no strain on your generator. It takes much longer for wear and tears to catch up with them because they are more heavy-duty.
This does not take away the need for regular checking and periodic maintenance, however. Fuel and oil levels need to be monitored, along with cleaning to get rid of dust and debris buildup, mold, moss, and fuel tank deposits. This elongates its lifespan, increases reliability, and improves efficiency, ensuring it doesn’t fail when you need it to work.
To paint a clearer picture of what to expect from a quality 3-phase portable generator, we shall look at one of the market leaders in this category that has been positively reviewed by users globally;
Gillette Generators’ GPE-75EH 3-Phase Portable Generator
- This is a consolidation of all the 3-phase benefits discussed above in a compact and portable package.
- The stated run time of this quality generator is an impressive 8.4 hours at three-quarters of its maximum load, meaning that it can serve you for days because you will be using it sparingly in an emergency.
- It is powered by a Honda OHV (overhead valve) engine, designed to take up minimal space protected by a 3-year warranty.
- A 3,600 RPM horsepower ensures the torque is adequate to start the generator and maintain a constant output.
- There is adequate space to fit an 8 gallon (30.2L) metal fuel tank, which should be adequate to keep it running for an entire cycle.
Investing in a 3-phase portable generator is a decision that will keep upholding itself every time you need to survive outdoors or during disasters that result in damaged power grids.
It makes it effortless to provide lighting and to power any electrical tools you may need. You will have acquired a flawless continuous and reliable power supply capable of supporting both sensitive and heavy appliances.
