mercury arc valve वाक्य

उदाहरण वाक्य

1. Mercury arc valves for HVDC were rugged but required high maintenance.
2. Mercury arc valves were also used on the following HVDC projects:
3. The mercury arc valves of Pole 2 were replaced later by Siemens.
4. The original link used mercury arc valve converters, and was rated at.
5. In 1977 one mercury arc valve group was replaced by a thyristor valve group.
6. See HVDC # Mercury arc valves.
7. Consequently, converters built with mercury arc valves are known as line-commutated converters ( LCC ).
8. The mercury arc valves were decommissioned on 1 August 2012, ahead of commissioning of replacement thyristor converters.
9. The mercury arc valve current-voltage characteristics are highly dependent on the temperature of the liquid mercury.
10. Mercury arc valves require an external circuit to force the current to zero and thus turn off the valve.
