Converter Transformer Market by Application, by ... converter transformer is one of the most important components in an HVDC converter station. Converter transformer plays a vital role in terms of total cost of an HVDC converter station, as it affects the performance of the entire connected electric power system. A converter transformer is used to step-up the voltage of the AC supply network.
VLF insulation testing - Megger testing uses very low frequencies as part of an AC cable maintenance routine. VLF testers are smaller and more practical than AC testers but output the same amount of power as a 50 Hz mains device. This combination of size and power makes Very Low Frequency cable testing perfect for testing longer sections of cable and apparatus.

ANSI MV GIS compact switchgear SafePlus - Gas insulated ... is a metal-enclosed compact switchgear system for distribution applications from 6 to 40.5 kV. The switchgear has a unique flexibility due to its extendibility and the possible combination of fully modular and semi-modular configurations. SafePlus uses SF6 (Sulfur hexafluoride) as an insulation and quenching medium.
Transformer Insulating Oil - Transformer Insulation System Insulation System. Each transformer has its own complex system of insulation. There always must be a combination of solid and fluid (or liquid) insulating components. There is a plenty of possible insulating materials, but there are also the most common types. Transformer insulation can also have major and minor insulation.
PROMOTioN - Work Packages Structure using HVDC-GIS, the volumetric space of the switchgear installation itself can be drastically reduced e.g. by 70%- 90% which may result in a size reduction of circa 10% of the total converter platform. Users intending to employ gas-insulated HVDC systems expect high reliability and long-term performance.
