The power supply of alternating current is classified into single-phase power supply and three-phase power supply. Single-phase is also called residential power supply because it is mostly used in small houses and residents. It is a power supply in which the supply voltage of power changes continuously. Moreover, it uses two wires i.e. Neutral and Phase wire. Phase wire carries the load while neutral wire acts as a returning wire of currents. Furthermore, in a single, power isn’t deliver constantly because the voltage keeps on rising and falling continuously.
Single Phase Power supply differences to that of Three Phase Power supply are:
Voltage wave of Single Phase Power and Three Phase Power Supply:
In a single phase, the phase uses a single alternating current voltage wave in its phase and a neutral wire. So, it is simple.
Whereas, the three-phase uses three alternating current voltage waves in its three live wires 120 degrees apart from each other. Sometimes we can see neutral wire in three phases too. It is more complex than a single phase.
Uses:
As the single phase is simple, it is mostly use in houses to run small appliances like televisions, refrigerators, fans, small motors, and other small electronic equipment.
Moreover, three phases are used in industrial and commercial buildings to run heavy machinery like heavy motors, generators, and HVAC systems due to their high supply of power.
Maximum voltage capacity of Single Phase Power and Three Phase Power:
The maximum voltage reach of a single phase is 230 volts. While three phases can carry a capacity of 415 volt.
Power interruption:
Power interruption can be seen if there is problem in wire as there is only one phase wire. In three phases there are three phase wires so if the problem is detected in one phase the others will continue to carry the load without the fear of power interruption.
In conclusion, single and three-phases are different choice of power supply as per their capacity. Contact Dharabijuli Services Pvt.Ltd for installation. We provides the best services in Kathmandu, Bhaktapur, Lalitpur.
