3 Phase Installations Projects
3 Phase Installations what are they? Electric power is a common method of alternating-current electric power transmission. It is a type of polyphase system, and is the most common method used by electric power distribution grids worldwide to distribute power. It is also used to power large motors and other large loads. A three-phase system is generally more economical than others because it uses less conductor material to transmit electric power than equivalent single-phase or two-phase systems at the same voltage.
In a three-phase system, three circuit conductors carry three alternating currents (of the same frequency) which reach their instantaneous peak values at different times. Taking one conductor as the reference, the other two currents are delayed in time by one-third and two-thirds of one cycle of the electrical current. This delay between “phases” has the effect of giving constant power transfer over each cycle of the current, and also makes it possible to produce a rotating magnetic field in an electric motor.
Three phase systems may or may not have a neutral wire. A neutral wire allows the three phase system to use a higher voltage while still supporting lower voltage single phase appliances. In high voltage distribution situations it is common not to have a neutral wire as the loads can simply be connected between phases (phase-phase connection).
Do I need a 3 phase Installation ?
If you think you would benefit from a 3 Phase system, please call Electric City on Freephone 0800 0345 240 we would be happy to visit your site and advise you. We will supply a free no obligation quote if we believe its a suitable option for you and discuss with you the pros and cons of the system for both long and short term so you can make an informed decision on whether to inverst in a three-phase system.
