Example Formula
The main formula for calculating the total power in a three-phase system, given the voltage (V) and current (I), is as follows:
- P: This denotes the total power in the system, measured in watts (W).
- √3: This is the square root of 3, arising from the geometry of the phasor representation of a three-phase system.
- V: This denotes the line-to-line voltage of the system, measured in volts (V).
- I: This represents the line current of the system, measured in amperes (A, named after the French physicist André-Marie Ampère).
- cosφ: This is the power factor, which signifies the phase difference between the voltage and current.
Who wrote/refined the formula
The three-phase system was first developed by Nikola Tesla in the late 19th century. This system and its associated formulas have been pivotal not only in the field of Physics but also in Electrical Engineering, Power Systems Engineering, and many industrial applications.
Real Life Application
Three-phase electric power is extensively used in power grids, electric motors in industries, and high-power applications like HVAC systems. A significant application is in the power transmission over long distances, where it improves the efficiency and reduces the power loss compared to single-phase systems.
Key individuals in the discipline
Nikola Tesla, a pioneering electrical engineer, and physicist is a key figure in the development of three-phase electric power. His patent in 1887, "Method of converting and distributing electric current," introduced the concept of three-phase electric power, forever changing the way power is transmitted and used.
