Power System Network

A detailed explanation of the conversion and distribution of electric energy from the power station to consumer units.This post describes how electric energy moves from the power generating station through conductors of various sizes to consumers premises.To minimize losses and for economical reasons, electrical energy has to be converted into different magnitudes during transmission and distribution until the consumer load.

Effects of Excess Current on the human body

Below 1 milliamperes (<1mA)
Generally not perceptible

1 milliamperes (1mA) 
Faint tingle.

5 milliamperes (5mA) 
Slight shock felt. Not painful but disturbing. Average individual can let go. Strong involuntary reactions can lead to other injuries.

6-5 milliamperes (6-5mA)
Painful shock, loss of muscular control. The freezing current or "let-go" range. Individual cannot let go, but can be thrown away from the circuit if exterior muscles are exited by the current.
