Tank - Name of power station - capacity
1 - Vindhyachal Thermal Power Station - 4,760MW.
2 - Mundra Thermal Power Station - 4620 MW
3 - The Sasan Ultra Mega power plant - 3960 MW
4 - The Tiroda thermal power plant - 3300 MW
Intern turn winding fault can be easily detect by differential protection relay.
Also detect by buchholz relay (gas operated relay), cause buchholz relay is used to detect the internal fault of transformer.
Condition of good conductor:
σ/ϵω >> 1
Equation is given by:
The constant ratio = σ/ϵω
σ/ϵω >> 1.
hence sea water is a acting as a good conductor Since attenuation is 90%, so transmission is 10%
e^(-αx) = 0.1
Attenuation constant = √(σμϵ/2)
-αx = ln(0.1)
x = 3.27 m
In DC microgrid system,
Efficiency α 1/Pin
For 1 kW loss injecting power is 20 kW
For 1.5 kW loss injecting power will be proportional to 30 kW
Efficiency will be reduced 0.025
