The system of power supply is categorized into two types namely single-phase power supply and three-phase power supply. For most industrial and business settings, three phase supply is used to run the high loads, whereas homes are generally supplied by a single phase, because home appliances require less power. A typical single-phase power system contains three wires, a power wire, a neutral wire and an earth/ground wire. A three phase power supply one, on the other hand, comes in three power wires, a neutral wire and an earth/ground wire that is often optional.
Three phase system-What is it?
As defined by Aegispower , “ A 3-phase system has three power wires, each 120⁰ out of phase with each other. Delta and wye are the two typesof circuits use to maintain equal load across a three-phase system, each resulting in different wire configurations. In the delta configuration, no neutral wire is used. The wye configuration uses both a neutral and a ground wire”. All three phases of power enter the cycle by 120⁰.When a complete cycle of 360⁰ is completed, three phases of power each peak in voltage twice. It is to be noted that with a three-phase power supply, a steady stream of power is delivered at a constant rate, making it possible to carry more loads.
Three Phase Supply Benefits
The benefits of choosing a three phase supply include the following:
Copper Utilization Reduction
Lessening of Security Risks for Employees
Labor Treatment Costs
The efficiency of the Conductor is Greater
Facility to Run High Power Loads
Three Phase Supply Applications
The applications of the three phase supply include the following:
These types of supplies are used in power grids, mobile towers, aircraft, shipboard, as well as other electronic loads larger than 1000 watts.
They are preferred in industrial, manufacturing, and large businesses.
