The recent years after the first edition of this book has been published are characterized by many developments in electric power generation, transmission, and distribution, e.g., the increasing application of renewable energy, the extensions of the AC transmission voltages to the UHV level >800 kV, the wider application
of HVDC power transmission, also by using cable systems, and improved methods
of diagnostics and condition assessment. All these advances are of consequence for
the high-voltage test and measuring technique. The second edition of this book shall
reflect the trend in HV testing and should be understood as a contribution to the
present impetus of high-voltage engineering in general.
Also for this second Edition, we have been supported by many colleagues and
mention Dr. Ralf Pietsch, Günter Siebert and Uwe Flechtner. Especially, we
acknowledge the cooperation with Dr. Christoph Baumann, Petra Jantzen and
Sudhany Karthick of Springer Nature.
