Characterisation of Polytetrafluoroethylene Nozzle Failure in Ultra‐High Voltage Circuit Breakers

Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.
ABSTRACT Polymeric nozzles used in the arcing chamber of high‐voltage circuit breakers confine the arc and regulate the gas flow, but are prone to ablation surface damage, stress cracking and other adverse changes when exposed to a harsh arcing environment—a long‐standing problem that limits the electrical and mechanical endurance of the switching ...

Accurate Harmonic Voltage Measurement Based on Series Resistive‐Capacitive Divider for Gas‐Insulated Switchgear

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
A series resistive‐capacitive divider for harmonic voltage measurement of gas‐insulated switchgear was studied. It can step down the voltage while amplifying the proportion of harmonics in the total sensed voltage, thereby increasing the significant figure for the measurement and enabling the accurate measurement of high‐order, low‐amplitude harmonics.
