Introduction of Distribution Electrical Transformers – How Transformer Works?

In general understanding electrical distribution transformers are used to reduce primary system voltages (which is normally 2.4-34.5kV) to the level of utilization voltages i.e. 120- 600V. International electrotechnical commission standards do not distinguish between distribution electrical transformers and power transformer. They are all power electrical transformers in the sense that …

Ideal Transformer Equations

An ideal transformer is a theoretical, linear transformer that is lossless and perfectly coupled; that is, there are no energy losses and flux is completely confined within the magnetic core. Perfect coupling implies infinitely high core magnetic permeability and winding inductance and zero net magneto-motive force. Ideal transformer equations By Faraday’s …

Transformers Maintenance & EMF Equation of a Transformer

Power transformer is most costly and essential equipment of an electrical system. It is well known fact that power transformers are the heart of the power systems which enables to establish very large power systems networks. Failure of any transformer will create critical situation in power distribution network hence extra …

Sinusoidal Voltage

A sinusoidal voltage can be described by the equation: v(t) = VM sin (ωt + Φ) or v(t) = VM cos (ωt + Φ) where v(t) Instantaneous value of the voltage, in volts (V). VM Maximum or peak value of the voltage, in volts (V) T Period: The time taken …
