Advantages of Three-Phase System
Electrical power is generated, transmitted and distributed in the form of 3-phase power because it has the following advantages over the single phase system −The three phase power has a constant magnitude while the power in single phase system is the function of supply frequency i.e. pulsates from zero to maximum value at twice the supply frequency. It can be seen from the following equations, 1 − phase power, $$p=\frac{V_{m}I_{m}}{2}-\frac{V_{m}I_{m}}{2}\cos2\omega\:t$$3 − phase power, $$p=\sqrt{3}(V_{L}I_{L}\cos\varphi)$$In the 3-phase system, a rotating magnetic field can be created in stationary windings, whereas this cannot be done in a single phase system.For the same rating, ...
Read MoreAbsolute and Relative Magnetic Permeability (μ)
Absolute Magnetic PermeabilityThe absolute (or actual) magnetic permeability of a material is its conductivity for the magnetic flux. It is denoted by a Greek letter μ ‘(mu)’ and measured in Henry per meters (H/m). Thus, Absolute permeability of material, $$\mu=\mu_{0}\mu_{r}\:H/m$$Where, μ0 = absolute permeability of air or vacuum.μr = relative permeability of the material.The higher the permeability of a magnetic material, the greater its conductivity for magnetic flux and vice-versa.Air or vacuum is the poorest conductor of the magnetic flux. The absolute magnetic permeability of the air is μ0 = 4π × 10−7 H/m . The absolute permeability (μ) of a ...
