The Difference between 3-Phase Factory Electricity and 1-Phase Ordinary Electricity

What is the difference between 3-phase and 1-phase electrical systems? Which model is suitable for factory and warehouse applications. Typically, we are familiar with is the 1-phase power system for ordinary uses. In this article, we present the distinction between these two types and illustrates why the 3-phrase system is more suitable for industrial purposes. The utilization of electricity in factories and warehouses differs significantly from household electricity. Besides, specialized factories would demand different electrical designs, which are unique to their operations.

Here, we would briefly provide brief descriptions of these two distinct electrical systems. Also, we would explain why the 1-phrase electrical network is for household uses, while the 3-phrase system is for industrial applications.

The Difference between 3-Phase Factory Electricity and 1-Phase Ordinary Electricity

1-Phase Electrical System

For the electricity we commonly associate with, typically in our homes, we would come across the 1-phase power system. This system is sufficient for the electricity demands. When you inspect your lightbulbs and electrical appliances, you will notice they have two electrical wires and have a voltage of 220 volts.

This standard electrical connection processes two channels to provide electricity. The 1-phrase circuit would comprise of two wires: one current line(Current), and the neutral line (Neutral). These two wires are sufficient for domestic uses.

Sometimes, you may come across the third slot, which is the ground line (Ground). The third slot completes the circuit. When there is an electrical surge or leakage, this wire will route the excess current to the ground. This complete circuit offers safety for electrical uses in typical homes.

3-Phase Electrical Circuit

The 3-phase power system consists of 4 electrical wires and has a voltage of 380 volts. In this arrangement, three wires carry electrical current while the fourth is idle and has no electricity. We typically call the fourth wire the Neutral Line.

Most factories and warehouses employ 3-phase electrical systems because the demands of electricity in factories and warehouses are incredibly high. Whether heavy machines, cooling systems, or convoluted lighting systems, factories, and warehouses require a constant high-voltage supply of power.

Also, the installation of this system is more complex and hence more expensive. You have to evaluate its installation fees carefully. Another associated cost in this type is the application fees charged by relevant electric authorities. The 3-phrase system is more expensive to apply.

However, its crucial benefit is, in the long run, it saves more on electricity bills. On heavy electricity uses, the rates for this type of circuit is substantially lower than the 1-phrase system. Another benefit of this system is that you can still use 1-phrase appliances as well. Moreover, you can design the electrical system within your factory and warehouse more effectively. For example, usually, your office areas would require less power, and thus you can utilize the 1-phrase system in this area to save costs on the cables and installations. For factory and warehouse areas, the voltage demands are considerably higher, and you should utilize the 3-phrase system.

The 3-phase power system is a more cost-effective system when your operations rely on substantial electricity uses. Therefore, it is more fitting to utilize the 3-phase circuit for factory and warehouse purposes.

Hopefully, our comparisons would help you better understand the distinctions between these two systems. For factory and warehouse purposes, the 3-phrase system is the more viable choice. Although the initial costs associated with this circuit type are higher the single-phrase electricity, the overall electricity costs would be more economical in the long run. Furthermore, you can expect a constant supply of high-power electricity essential to your factory and warehouse uses.
