To lower the lightning impulse withstand voltage of gas insulated switchgear (GIS) while maintaining the high reliability of its insulation performance, it is important to define in an organized way the insulation characteristics for non-standard lightning impulse voltage waveforms that represent actual surge waveforms in the field and compare them ...

To lower the insulation specifications (specifically, the lightning impulse withstand voltage) of oil-immersed transformers and thus reduce equipment cost while maintaining high insulation reliability, it is required to identify the insulation characteristics under non-standard lightning impulse waveforms that are associated with actual surge waveforms

High-Accuracy Comparison of Lightning and Switching Impulse Calibrators
IEEE Transactions on Instrumentation and Measurement, 2007This paper summarizes the results of a comparison on two calculable impulse voltage calibrators and one commercial calibrator between Helsinki University of Technology, Finland (MIKES-TKK), Nippon Institute of Technology, Japan (NIT), and Physikalisch-Technische Bundesanstalt, Germany (PTB).

Robust evaluation procedure for lightning impulses
Proceedings of the 7th International Conference on Properties and Applications of Dielectric Materials (Cat. No.03CH37417), 2004The existing recommendation for high voltage tests, IEC Publication 60060, is ambiguous in the evaluation of the impulse test voltage, when oscillations or overshoot are superimposed on the peak of the smooth, double exponential waveshape. Particularly impulse tests on transformers may be critical due to the high stress on the insulation during the ...

Virtual Instrument for Lightning Impulse Tests
IEEE Transactions on Power Delivery, 2007We propose an objective formulation of the impulse analysis problem from a signal analysis viewpoint. The winding response is quintessentially that of a deterministic network to a finite energy signal, with breakdown and partial discharge being inherently nonlinear events.
