What is the Difference between Three-phase Diesel Generator and Single-phase Diesel Generator

by Dieselgenerator Tech ***

When buying generators, we often talk about three-phase diesel generators and single-phase diesel generators, but many users don’t understand the terms “three-phase” and “single-phase”. In this article, professional generator manufacturer, Dingbo Power will introduce to you the essential difference between three-phase diesel generators and single-phase diesel generators as following.

1. The single-phase voltage is 220 volts, the voltage between the phase line and the neutral line; the three-phase voltage is 380v between a, b and c, and the electrical appliance is a three-phase 380v motor or equipment. Three-phase electricity is mainly used as the power source of the motor, that is, the load that needs to rotate. Because the three phase differences of the three-phase electricity are all 120 degrees, the rotor will not be stuck. The three-phase electricity is to form this "angle", otherwise, the manufacturer does not need to engage in such a complicated three-phase electricity.

2. Three-phase diesel generators are used in industrial production, and their voltage is 360v; single-phase diesel generators are used for ordinary residents' lives, and their voltage is 220v.

3. Three-phase diesel generators have 4 wires, of which 3 are 220v live wires and 1 is a neutral wire. Combining any live wire with the neutral wire is what we usually call commercial power, that is, 220v electricity; but for the balance of the three-phase power, the manufacturer recommends that it is the best to connect the corresponding load if possible.

4. Three-phase electricity can provide more reasonable power energy. In terms of motor energy, no other things are needed. As long as the three-phase electricity is directly connected to the motor, the motor can run. If it is a single-phase motor, a complicated thing needs to be added to the motor to ensure the motor runs.

Through the above introduction, We believe that the majority of users understand that when choosing a generator, it is necessary to understand our own needs, and then choose according to our own needs to decide whether we need a single-phase diesel generator or a three-phase diesel generator, no matter which one you choose, we are always ready to service you by any time.
