Why do most mechanical manufacturers use three-phase motors and less use single-phase motors
Why do mechanical manufacturers mostly use three-phase motors and less use single-phase motors? What are the differences between three-phase electricity and three-phase electricity? Today, Hengli Motor will take a look at the advantages of three-phase electricity!
Advantages of three-phase electricity: 1. In terms of power generation, it can increase power by 50% compared to single-phase power sources; 2. In terms of power transmission, it saves 25% of steel compared to single-phase transmission; 3. In terms of power distribution, three-phase transformers are more economical and easier to connect to loads than single-phase transformers; 4. Electrical equipment: It has the advantages of simple structure, low cost, reliable operation, and easy maintenance.
The above advantages have made three-phase circuits widely used in power supply and are currently the main power supply method adopted in power systems.
Precautions for three-phase power measurement
The two meter method can only be used under the conditions of three-phase three wire system, regardless of load symmetry.
Under the condition of three-phase three wire system, only the two meter method can be used.
The algebraic sum of the readings from two meters in the two meter method is the total three-phase power, and the individual readings from each meter are meaningless.
