Zusammengesetzte und kombinierte Hochspannungswellenformen - Kalibrierung und Standardisierung
Dr. Johann Meisner was born in Lusino, Russia, in 1982. After his school education in Russia and Germany he received his Diploma Engineer degree in the field of electrical engineering at the Technische Universität Braunschweig in 2010. Since 2010 he has been working in the department for electrical energy measurements at the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany. During this time he was involved in several national and international projects and comparisons. In 2014 he received his doctor of engineering degree (Ph.D.) from the Technische Universität Braunschweig, Germany. The Topic of his dissertation is “Metrology for HVDC energy supply”. It has been undertaken at the Physikalisch Technische Bundesanstalt (PTB). The main research of Dr. Johann Meisner includes the field of high-voltage and high-current measuring techniques. From 2015 to 2021 he is was the leader of PTB’s working group “High-voltage metrology”. Since 2021 he is leading the working group “Instrument Transformers and High Voltage Metrology”. Dr. Johann Meisner is involved in the national (VDE DKE) and international (IEC) standardization and several CIGRE working groups in the field of high voltage and high current metrology. Furthermore, he is the Coomet speaker of the Electricity Division of PTB and is involved in the Euramet P&E group. He is a steering committee member of the European Metrology Network EMN “Smart Electricity grids”.
Combined and composite high-voltage wave shapes calibration and standardisation
Electrical energy supply and distribution grids will be subjected to enormous changes as part of the sustainable energy transformation. The change from generation in large power plants to decentralised sources of energy, means gigantic tasks for high-voltage measurement technology. HVDC cable lines can be mentioned here as an example. The testing of components of future transmission grids often requires the application of superimposed voltage forms. These so-called combined or composite voltages are carried out in the test laboratories without sufficient metrological traceability and standardisation. Within the “European Metrology Programme for Innovation and Research” (EMPIR) a project was started, named 19NRM07 HV-com², which deals with traceable measurements of voltages at composite and combined tests. In this project, new low-voltage generators, measurement evaluation software and measurement systems up to 400 kV were developed. Thereafter traceability for high-voltage measurement systems and calibration services for composite and combined waveforms was established at the participating national metrology institutes. Several high voltage intercomparison campaigns were successfully carried out. At the same time, the research results were integrated into the ongoing revision of the IEC 60060 series. This paper presents the results of the project and the standardisation work.
