Do You Require A Single or Three Phase Generator?

Posted by Aurora Generators on

There are two types of systems available in electric circuit:

  •  Single Phase - Normally for residential use  
  • Three Phase - Primarily for Industrial use
  •  

  •  

    Single-phase and three-phase generators provide power differently. The most obvious evidence of this is seen in power delivery. Both types provide AC power, but a three-phase system produces three separate waves of power, delivered in sequence. This ensures a continuous uninterrupted flow of power that never drops to zero and makes three-phase generators more powerful than single-phase generators.

    Single-phase generators deliver one constant wave of power however, the power level varies with the electrical current coming in. That means power levels can drop to zero during the cycle. This happens very quickly and is undetected by humans and rarely has an effect on whatever device is being powered. In fact, residential power is single phase and there’s never a problem powering devices in our homes. But for very large and demanding power applications, this dip can cause harm which is why three-phase systems exist.


    The easiest way to visualize these power differences is to imagine a wave. One single wave (i.e. a single phase system) starts at zero, goes up to the peak, and goes back down to zero before the next wave starts. In a three-wave system, the three waves in sequence each individually look and act the same as the single wave, but since they arrive in sequence, their total power overlaps a bit providing more power than the single phase circuit, keeping that power always above zero, and distributing the total load over three phases/waves so there is less draw on one single wave.

    It All Comes Down To Power Needs
    If you’re questioning whether you need a single-phase or a three-phase generator, you need to think about your power needs and your budget. Single-phase systems are less complex and less costly. They are more common in residential or rural applications where the loads are relatively small. Unsurprisingly, 3-phase systems are more costly to install and maintain, but depending on your power needs, they may be a necessity.


    3-phase systems are ideal for high-capacity settings which is why you usually only see them in industrial and commercial areas. Data centers, in particular, benefit from 3-phase backup generators due to the increased distribution capacity. 3-phase systems can power multiple racks whereas single-phase systems cannot.

    If your generator system will power air-conditioning units, pumps, heat pumps, well pumps, a welder’s shop, or irrigation pumps and you need assistance calculating your service size, please let us know. We will make sure you get the right size. Aurora Generators will provide this service free of charge of course. We will ensure that when your generator is built, the voltage is set. All generators are tested and load tested before leaving our factory.

    Our reps are trained to recommend only what's best for you, the valued customer. We will never try to upsell you on something you do not need. We prefer, to be honest, and gain your trust since word of mouth advertising is the best source of advertising. Call us today to discuss your generator needs at 1-877-510-6807.
