What is the purpose of a converter station?
What are converter stations and substations? A converter station converts electricity between Alternating Current (AC) and Direct Current (DC). AC is used in each country’s transmission system, while DC is used for sending electricity long distances along the subsea cables.
How far can you transmit DC power?

| DC 100mA | 216 feet | 1,379 feet |
| DC 200mA | 108 feet | 689 feet |
| DC 300mA | 72 feet | 459 feet |

How many HVDC are there in India?
HVDC Bipolar Links There are currently five operational HVDC links in India namely Rihand-Dadri, Ballia-Bhiwadi, Chandrapur-Padge, Talcher-Kolar and Mundra- Mohindergarh.
What countries use HVDC?
The modern form of HVDC transmission uses technology developed extensively in the 1930s in Sweden (ASEA) and in Germany. Early commercial installations included one in the Soviet Union in 1951 between Moscow and Kashira, and a 100 kV, 20 MW system between Gotland and mainland Sweden in 1954.
What is the current margin at the converter station?
The frequency of the ripple in output voltage of the converter is determined by pulse number. 12. Current margin is typically about 10 % of rated current in current controller.
Do substations convert AC to DC?
An electric power substation whose main function is the conversion of power from ac to dc, and vice versa.
How far can you run 24v DC?

What is the highest transmission line voltage in India?
765 kV AC
Transmission voltage in India (highest) is 765 kV AC and these lines are erected by Power Grid Corporation for interstate connections throughout India.
Does Australia use HVDC?
In total, Australia in April 2020 has 3 x HVDC Underground and Subsea Interconnectors and 7 AC Overhead Interconnectors. This diversity of interconnection complexity and technology leads to fundamental questions that prompted this analysis.
Why DC is not used for transmission?
DC(Direct Current) is not used over AC(Alternating Current) in transmission because DC goes heavy attenuation while transmission over long distance as we do not transform it from Low Voltage (at which it is being generated) to High voltage (for transmission over long distance(I will explain…)) by some direct mean …
Why is DC used for transmission?
Alternating current travels as a wave, and is constantly changing direction (60 times per second, defined as 60 hertz, in North America). Since direct current does not involve oscillation, it decreases losses and allows electricity to be transmitted more efficiently.
