HVDC converter station — Wikipedia Republished // WIKI 2 converter transformers step up the voltage of the AC supply network. Using a star-to-delta or "wye-delta" connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components.The insulation of the transformer windings must be specially designed to withstand a large DC potential to earth.[email protected]

Major components you can spot while looking at HV/EHV GIS ...· Gas-insulated switchgear (GIS) is a piece of high voltage equipment that is being constantly developed day by day. The basics of GIS technology is more or less the same, but everything else under the hood is improved a lot comparing to just a few years ago. This article explains major GIS components and their characteristics.
Gas Insulated Switchgear Assembly (GIS) | Electrical ... insulated switchgear assemblies are gaining importance because of the innate advantage of compactness. Inert, non-flammable SF6 provides three times stronger insulation than air; hence using it as an insulation medium allows for drastic reduction of size and space for high voltage switchgear …

Dissolved gas analysis - Wikipedia gas analysis (DGA) is the study of dissolved gases in transformer oil.. Insulating materials within transformers and electrical equipment break down to liberate gases within the unit. The distribution of these gases can be related to the type of electrical fault, and the rate of gas generation can indicate the severity of the fault.
Gas Insulated Switchgear| Fuji Electric Global GIS (Gas Insulated Switchgear) Features Since the first operation of the phase segregated type GIS in 1970, Fuji has successfully developed as a standard series of phase segregated type or three phase encapsulated type GIS which realized a quite compact and very reliable construction.
Gas-insulated Switchgear (GIS) Testing - OMICRON Switchgear (GIS) Testing Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas.

Technical Guide No. 102 - ABB· PDF fileFigure 4 shows the relationship of insulation life versus temperature normalized at 25°C (100% life). Increasing the temperature to 130°C decreases insulation life to 83% from nominal. Increasing the temperature further to 155°C (Class F insulation limit) or 180 °C (Class H insulation limit) will further reduce insulation life.
