Breakdown of the AC Voltage General Equation
By using a simple wave equation we can characterise a time varying AC voltage signal. In this topic we break down each component with examples.
Transformers & Equivalent Circuit
Transformers not only step up or down voltages but they are widely used fore they DC blocking capability. Let's dig in and see the working principle.
Power Output of Synchronous Machines
About the Synchronous Reactance Model, phasor diagram, leading and lagging power factor in generators/motors due to over/under-excited field current.
Induction vs Synchronous Machines
Induction Machines, that always lag behind the synchronous speed, are a simpler from of Synchronous Machines. Let's go into bit more detail about them.
3-Phase Power & Distribution
3-Phase Power is distributed either by a Delta or Star configuration. This topic focuses on the derivation of power, power factor and efficiency.
Transmission Lines & Electricity Distribution
Power Plants generate electricity that is carried to the cities by Transmission Lines. Although, this is is a little complicated due to ohmic losses.
Thermodynamics Made Simple
Thermodynamics consists of a set of laws that characterise a system based on temperature, energy and entropy. When we say 'system', think about a hob..
Renewables: Hydropower
Hydropower is where the flow of water is converted to electrical energy. This topic covers the various types as well as focuses on energy calculation.
Renewables: Solar Power
Photovoltaics is the principle of converting light to electricity. The topic describes the solar power calculation and the idea behind this technology.
Renewables: Wind Turbines
Wind Turbines are one of the most common alternatives to fossil fuels. This topic analyses the efficiency as well as derives the formula for power.
