Abstract Ester liquids (ELs), as the 2 Pc. Sectional alternative transformer liquids to the conventional mineral oils (MOs), have been increasingly used in power transformers with high voltage ratings.Among various properties, the lightning impulse breakdown voltages (LIBDVs) have been studied elaborately in the past two decades under different ele
The development of adaptive and intelligent clamping devices allows for the reduction of rejects and defects based on weld discontinuities in laser-beam welding.The utilization of fixture-integrated sensors and actuators is a new approach, realizing adaptive clamping devices that enable in-process data acquisition and a time-dependent adjustment of
