Finite element analysis of reinforcement for gas insulated switchgear

Highlights in Science, Engineering and Technology, 2023
Considering the burgeoning requirement for reinforcing gas-insulated metal-enclosed switchgear, a three-dimensional elastic-plastic finite element model was established to examine the stress distribution before and after reinforcement. The results showed that, under an internal pressure of 3.8 MPa, the maximum stress of the defective sample surpassed ...

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.
