Introduction to High Voltage and Electrical Field
Classification of HV
MHV;
1kV to 70kV
HV:
110kV to 230kV
LV :
< 1kV
EHV:
275kV to 800kV
UHV:
>1000kV
Main Components of Power Systems
TRANSMISSION
TL tower
Conductor/cable
Insulators
SUBSTATIONS
Transformer
CB
Surge arrester
Protect the insulation and conductors of the system from damage due to lightning
switch
POWER PLANT
Generator
Turbine
Reactor
Methods To Determine The Potential Distribution
Analytical calculation of space charge free fields
Experimental analogues for space charge free fields
Numerical computation
Applications of HV
X-ray generators and particles accelarators
High power lasers and ion beams
Ozone generation for water and sewage treatment
Capacitor charging
Plasma creation
HVDC vs HVAC
Low construction cost
: Unipolar connection (single line + ground)
Deliver more power
in long distance(Reduce losses)
Enviromental friendly:
Less CO2 emission
Asynchronous
: No frequency to be worried about
