12 essential parameters required for rating large generators
When specifying generators, the first thing that comes to mind is a rating. The machine’s rating is a set of parameters that, simply speaking in engineering terms, describe the generator. These values indicate the generator’s available power output as well…...

What is the complex power and how it figures in power analysis
Considerable effort has been expended over the years to express power relations as simply as possible. Power engineers have coined the term complex power, which they use to find the total effect of parallel loads. Complex power is important in… Read more

The basics of power in alternating current circuits (you MUST NEVER forget)
In a DC circuit, the power is equal to the voltage times the current, or P=V×I. This is also true in an AC circuit when the alternating current and voltage are in phase. That is, when the circuit is resistive…. Read more

Heat vs. Current in a Resistor
It is converted from one form to another. One of the most familiar forms of energy is heat. When a current (I) is forced through a resistor (R) by applying a potential (V), the electrical energy is converted to heat… Read more

How reactive power is helpful to maintain a healthy system
We always tend to reduce reactive power to improve system efficiency. This is acceptable at some level. If the system is purely resistive or capacitance, it may cause problems in the Electrical system. AC systems supply or consume two kinds… Read more
