4. Cometa (HVDC) - Wikipedia

   en.wikipedia.org/wiki/Cometa_(HVDC)

   COMETA (abbreviation for COnexión MEditerránea Transporte Alta tensión; also known as the Majorca–Valencia interconnector and the Romulus project) is an undersea electric power transmission system between mainland Spain and the island of Majorca. It connects Morvedre near Valencia and Santa Ponsa near Palma de Mallorca.

5. HVDC converter - Wikipedia

   en.wikipedia.org/wiki/HVDC_converter

   For this reason, an HVDC converter using IGBTs is usually referred to as a voltage-source converter (or voltage-sourced converter [26]). The additional controllability gives many advantages, notably the ability to switch the IGBTs on and off many times per cycle in order to improve the harmonic performance, and the fact that (being self ...

6. Multifunction tester - Wikipedia

   en.wikipedia.org/wiki/Multifunction_tester

   Multifunction testers are able to perform continuity tests (or low ohms resistance tests) and insulation resistance tests (or high ohms resistance tests) and they may also be able to perform earth fault loop impedance tests, prospective short-circuit current tests, earth electrode tests and RCD tests.

7. Power electronics - Wikipedia

   en.wikipedia.org/wiki/Power_electronics

   DC link converters: DC Link Converters, also referred to as AC/DC/AC converters, convert an AC input to an AC output with the use of a DC link in the middle. Meaning that the power in the converter is converted to DC from AC with the use of a rectifier, and then it is converted back to AC from DC with the use of an inverter.

8. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power Converters can include simpler tools such as transformer or more complex like a resonant converter.

9. HVDC converter station - Wikipedia

   en.wikipedia.org/wiki/HVDC_converter_station

   When line commutated converters are used, the converter station will require between 40% and 60% of its power rating as reactive power. This can be provided by banks of switched capacitors or by synchronous condensers , or if a suitable power generating station is located close to the static inverter plant, the generators in the power station.
