Typical AC Power Supply system (Generation, Transmission and Distribution) scheme and Elements of Distribution System (a complete note With Diagrams)

Typical AC Power Supply system scheme The lines network between Generating Station (Power Station) and consumer of electric power can be divided into two parts. Transmission System Distribution System We can explore these systems in more categories such as Primary transmission and secondary transmission. Similarly primary distribution and secondary distribution. This is shown in the below image (One Line or Single Line diagram of Typical...

Why the reactance of a system under fault condition is low and faults currents may raise dangerously high value. ? (With simple example)

 Because the total Power is same, and under fault condition (Short circuit)…There is no load (Impedance (Z), or Reactance ( XL)= Resistance, and in case of no load, there will be no reactance or resistance, so current will be high) in this condition…So current will be too high, and when power is same, and current increases, voltage will be decrease. Example, Suppose, (In normal condition)  P= 10 watt, V = 5 Volts, and Current = 2 Amp. But in Short circuit Condition, (When current is too high) Then, P = 10 Watts,   ...

Primary and Secondary or Backup protection in a Power System

Primary Protection Below is the power system protection scheme which is designed to protect the power system parts and components. As shown in below fig, each line associated with over current relay that protect the lines from faults. So, if a fault happens on any line, it will be cleared by its relay and circuit breaker. This is called primary or main protection and acts as a first line defender. The service record of primary relaying...
