13. UHV (1000kV) power transmission technologies
13.3 UHV sub-station facilities (OHP presentation)
Previous Next Contents

The main points to be considered in designing sub-station facilities are:
Transformer
Transportation by train and road to the erection location Insulation for high voltage & compact design
Surge arrester
Low limiting voltage level and high energy absorption capacity
Circuit-breaker
Parallel resistor for switching surge damping of huge capacity of energy absorption
Disconnector
Parallel resistor of compact size & high voltage withstanding
H.S.G.S
New technology, accurate operation
Bushing
Compact size, contamination & earthquake proof design
