Measuring the transient voltages, including lightning or switching impulse overvoltage, is
helpful for accident analysis of power system and insulation design. In this paper, a …

Transformer winding deformation is common among all sorts of transformer failures.
Cumulative deformation can eventually burgeon into catastrophic faults and result in entire …

Stable triggering of acquisition devices is critical to accurately measure electromagnetic
transients, especially for very fast transient overvoltages (VFTOs). A highly stable and low …

Most work about the measurement of very fast transient overvoltage (VFTO) was carried out
in the laboratory and test base. Because of the different GIS arrangement and power …

For the non-contact measurement system, the low frequency measuring and uncertainty
analyzing are critical to obtain the accurate amplitude of the transient overvoltage. In this …

The operation of disconnectors in gas insulated substation (GIS) or power plant will produce
very fast transient overvoltage (VFTO), which is considered to have serious harm to …

Measurement of lightning and switching transient overvoltage in power system is significant
to the research that guides the protection of power system. A new type of sensor for non …
