What happens if instead of one phase three

Many novice electricians, as well as ordinary people who are not versed in this field, do not know the difference between a single-phase and a three-phase connection. First of all, it is worth noting the fact that both types of power have a zero conductor, which is popularly referred to as "Zero". With respect to zero, all three phases have a voltage of 220 volts, while in relation to each other, the supplied voltage is significantly greater, namely 380 volts. This voltage is formed due to the fact that the current on three different phase wires differs exactly by a third of the cycle, namely 120 degrees. It is important that when creating a three-phase voltage, make sure that the consumption is approximately at the same level from each phase. Otherwise, you will have to deal with a phenomenon such as phase imbalance. The best protection against skew is a voltage relay.

Advantages and disadvantages of three-phase connection

The advantages of such a network include the following series of qualities:

• The power of the network is limited only by the cross-section of the wire.
• Significant energy savings appear.
• You can connect large industrial units that should only be powered by this kind of network.
• If the power goes out or there is a power outage, then you can switch to single-phase mode using only the “good” phase.

But do not forget about the disadvantages that are definitely there.

• Great price for installation, as well as network maintenance if necessary. The minus is very controversial, since the money invested in good equipment, as well as high-quality installation, can be recouped over time due to savings and other positive qualities.
• High voltage, which is many times more dangerous.
• The maximum power of single-phase loads is limited, which in many situations will be very important.

In modern realities, a tendency has developed that if you use a power consumption of less than 10 kW, then you do not make much sense to connect a three-phase power supply. In cases where there is a great need for using equipment with a power consumption of more than 10 kW, then of course you need to think about connecting a three-phase power supply. One of the most obvious examples can be a three-phase motor, or similar equipment. Thus, you will receive safety and energy savings, as well as other advantages that have been described previously.
