They know what they’re talking about

They are high­ly regard­ed by their fel­low experts, they have a wealth of exper­tise, and they are unit­ed by one thing: They are all work­ing for the Rein­hausen Group on find­ing the best tech­ni­cal solu­tions for net­work oper­a­tors, trans­former man­u­fac­tur­ers, and gen­er­al con­trac­tors.

Transformerautomation

Dr. Karsten Viereck, Director of Technology

Spe­cial­ist Area: Dr. Viereck has spent his whole career work­ing in the field of trans­former dig­i­tal­iza­tion. He start­ed devel­op­ing ini­tial mon­i­tor­ing sys­tems back in the 1990s. Today, he is a high­ly sought-after expert in this field of indus­try. His work focus­es on defin­ing algo­rithms and devel­op­ing appli­ca­tion mod­els. ETOS®, the sys­tem solu­tion for the automa­tion of pow­er trans­form­ers, rep­re­sents the cul­mi­na­tion of his exten­sive knowl­edge of trans­form­ers.

Works: Involved in sev­er­al dozen patents and a mem­ber of mul­ti­ple work­ing groups. Most impor­tant pub­li­ca­tion to date: “Guide on Trans­former Intel­li­gent Con­di­tion Mon­i­tor­ing Sys­tems”, a stan­dard work pub­lished by the Cigré Study Com­mit­tee for Trans­form­ers cov­er­ing algo­rithms, arti­fi­cial intel­li­gence, and mon­i­tor­ing pro­ce­dures.

Vision: The dig­i­tal­iza­tion of trans­form­ers con­tin­ues to move for­ward. In the future, the focus will be on incor­po­rat­ing arti­fi­cial intel­li­gence into trans­former diag­nos­tics.

Mis­sion: To under­stand cus­tomers and make their equip­ment fit for the ener­gy sup­ply of tomor­row.

Tap-Changer

Dr. Axel Krämer, Director of Technology

Spe­cial­ist area: As the expert in tap chang­ers, his exper­tise ensures that the only mov­ing com­po­nent in the trans­former is always state of the art. His knowl­edge is high­ly sought after by numer­ous stan­dard­iza­tion bod­ies.

Works: The book “On-Load Tap-Chang­ers for Pow­er Trans­form­ers” is, quite sim­ply, the defin­i­tive work on this com­po­nent. By pro­vid­ing appli­ca­tion-based help for trans­former man­u­fac­tur­ers and users, it aims to demys­ti­fy the tap chang­er and defy its rep­u­ta­tion as an unknown enti­ty in the field of elec­tri­cal engi­neer­ing.

Vision: The tra­di­tion­al tap chang­er with oil switch­ing tech­nol­o­gy will grad­u­al­ly lose sig­nif­i­cance. It will be super­seded by vac­u­um switch­ing tech­nol­o­gy, which will become wide­spread in the future. Der tra­di­tionelle Stufen­schal­ter mit Öl-Schalt­tech­nik wird nach und nach an Bedeu­tung ver­lieren. Die Zukun­ft gehört der Vaku­um-Schalt­tech­nik, die sich flächen­deck­end durch­set­zen wird.

Mis­sion: To man­age the bal­anc­ing act of com­ply­ing with strict­ly defined stan­dards while ensur­ing that they do not stand in the way of future devel­op­ments. This is the only way to ensure that cus­tomers can ben­e­fit from inno­va­tions.

Diagnostics and Sensors

Dr. Andreas Kurz, Head of Measuring & Diagnostics Center of Competence at Messko

Spe­cial­ist area: The two main aspects of his spe­cial­ist area are close­ly linked: Sen­sors are required in order to enable the diag­no­sis of elec­tri­cal equip­ment. The CoC focus­es on the dig­i­tal­iza­tion of switchgears and also devel­ops inno­v­a­tive and intel­li­gent sen­sor sys­tems. These sys­tems are com­bined with new kinds of algo­rithms to form unique eval­u­a­tion mod­els which pro­vide the cus­tomer with infor­ma­tion about the state of each indi­vid­ual piece of equip­ment at all times.

Works: Numer­ous pub­li­ca­tions in inter­na­tion­al spe­cial­ist media, inter­na­tion­al patents, mem­ber of var­i­ous expert pan­els includ­ing Cigré com­mit­tees (Con­seil Inter­na­tion­al des Grands Réseaux Élec­triques).

Vision: As a result of the ener­gy rev­o­lu­tion, oper­a­tors will increas­ing­ly have to decide on an ad hoc basis which node to use for sup­ply­ing ener­gy. This means that the sen­sors made by Messko under the umbrel­la of the Rein­hausen Group will become more impor­tant, as they pro­vide the nec­es­sary data. In this way, they will be help­ing to bring about the ener­gy rev­o­lu­tion.

Mis­sion: To use the dri­ving force of dig­i­tal­iza­tion and its impact on the field of ener­gy tech­nol­o­gy to estab­lish new, sus­tain­able approach­es.

High-Voltage Direct Current Transmission

Dr. Dazhong Shen, Senior Manager for Business Development for China

Spe­cial­ist area: Before Dr. Shen came to MR, he worked for a trans­former man­u­fac­tur­er. He now spe­cial­izes in the com­plex solu­tions that cus­tomers, par­tic­u­lar­ly those in the Chi­nese mar­ket, are ask­ing for. HVDC tech­nol­o­gy is a big part of this, as Chi­na has to be able to trans­port large quan­ti­ties of pow­er over large dis­tances at a high volt­age in an effi­cient man­ner.

Works: Togeth­er with Pro­fes­sor Zhou Ying­hao, a mem­ber of the Chi­nese Acad­e­my, Shen has writ­ten a text­book on on-load tap-chang­ers in HVDC con­vert­er trans­form­ers. The book explains all aspects of the design and oper­a­tion of these com­po­nents for the first time. It is already regard­ed as a stan­dard work.

Vision: Peo­ple will con­tin­ue to need more and more pow­er. But ener­gy sources are uneven­ly dis­trib­uted and are not always locat­ed where they are need­ed. This means that trans­port­ing pow­er over large dis­tances will become more and more impor­tant.

Mis­sion: To work with ener­gy sup­pli­ers and trans­former man­u­fac­tur­ers to devel­op the best tech­ni­cal solu­tions and to main­tain per­son­al con­tact with tech­ni­cians at all lev­els.

Testing and Measuring Technology

Thomas Steiner,
Technical Director at HIGHVOLT

Spe­cial­ist area: Stein­er is an inter­na­tion­al­ly renowned expert in high volt­age tests and mea­sur­ing tech­nol­o­gy. While he was still at uni­ver­si­ty, he con­struct­ed his own test bench and built a tran­sient recorder for his dis­ser­ta­tion project — a pio­neer­ing achieve­ment at the start of the 1990s. Today, he is in charge of a wide vari­ety of tech­ni­cal fields at HIGHVOLT and he works on devel­op­ing new test meth­ods togeth­er with his teams. He con­tributes his exper­tise to sev­er­al stan­dard­iza­tion bod­ies.

Works: Over 30 spe­cial­ist pub­li­ca­tions. He has been the spokesman for the TC42 com­mit­tee since 2008. He has con­tributed to numer­ous inter­na­tion­al stan­dards, includ­ing the com­plete devel­op­ment process for IEC 61083–3 which defines the stan­dards for mea­sur­ing equip­ment used in high-volt­age and high-cur­rent tests.

Vision: There is a glob­al trend toward high­er and high­er volt­ages for equip­ment. In this con­text, sophis­ti­cat­ed, intel­li­gent test­ing and mea­sur­ing tech­nol­o­gy will become more and more impor­tant.

Mis­sion: To solve cus­tomers’ prob­lems, even when they are at the lim­its of physics.
