Experience Report of Potential Free Temperature Measurement with commercially available Pyrometers in gas insulated systems

Autor: Hallas, Martin, Moxter, Julian, Hinrichsen, Volker, Juhre, Karsten, Tenzer, Michael

A potential free temperature measurement in gas insulated switchgear and lines (GIS/GIL) was investigated within an HVDC research project, because the temperature is of high importance during development and operation of HVDC equipment. Infrared spec

Comparison of superimposed voltage tests with spark gap and coupling capacitor at a gas-insulated model arrangement

Autor: Hallas, Martin, Hinrichsen, Volker, Tenzer, Michael

Superimposed voltage tests are widespread to qualify HVDC equipment. Two possible test circuits are used, which result in different voltage shapes: superimposition by a coupling capacitor or by a spark gap. So far, there is no data available, which c

General overview of AC and DC current injection on high voltage potential for HVDC long-term tests

Autor: Hallas, Martin, Hinrichsen, Volker

HVDC transmission systems like cables or gas insulated systems are of great interest for future grid expansions. They are usually type tested in one-year long-term tests, to ensure lifetimes up to 40 years and more. HVDC equipment always has to be te

Cigré Prototype Installation Test for Gas-Insulated DC Systems - Testing a Gas-Insulated DC Transmission Line (DC-GIL) for ±550 kV and 5000 A under Real Service Conditions

Autor: Hallas, Martin, Hinrichsen, Volker, Neumann, Claus, Tenzer, Michael, Hausmann, Bruno, Gross, Detlev, Neidhart, Thomas, Lerch, Maximilian, Wiesinger, Doris

More and more generation facilities are installed far away from the load centers. Thus, long distance transmission is demanded, and with this regard DC transmission systems are of special interest. Transmission by overhead lines is a well-proven tech

Comparison of Current Carrying Capacities and Investment Costs of Directly Buried HVDC Cable and GIL Transmission Systems

Autor: Balzer, Constantin, Hallas, Martin, Hinrichsen, Volker, Neumann, Claus, Koch, Herrmann

HVDC underground transmission is of high interest for future grid extension. Generally, directly buried DC cables and DC GIL are possible solutions, and both of them represent new technologies. This paper takes a first step in comparing their current

Nachweis der Betriebstauglichkeit von gasisolierten HVDC Systemen unter betriebsnahen Bedingungen – Resümee einer Langzeituntersuchung in Griesheim

Autor: Hallas, Martin, Tenzer, Michael, Neumann, Claus, Hinrichsen, Volker, Gross, Detlev

Im Rahmen der Präsentation wurde das GIL Testfeld in Griesheim vorgestellt. Direkt erdverlegte DC-GIL hat sich grundsätzlich als realisierbar erwiesen, thermomechanisch wie auch dielektrisch; ebenso wurde die neu entwickelte Versuchstechnik qualifi

Determination of AC test currents for thermo-electric laboratory stresses on gas-insulated HVDC systems

Autor: Hallas, Martin, Kosse, Maria, Juhre, Karsten, Secklehner, Maximilian, Hinrichsen, Volker

A particular challenge in the design of HVDC equipment is the accumulation of electrical charge carriers at gas-solid interfaces and in the bulk of the solid insulation material, which can cause locally increased electrical field stress. During opera
