Breakdown Voltage Using Bond Energy Calculation for CF3CHCl2/CO2 Mixture as Insulation Applied

JAREE (Journal on Advanced Research in Electrical Engineering), 2019
— Sulfur hexafluoride gas according to the Montreal Protocol and Kyoto protocol needs to be limited and gradually reduced because it causes global warming, the greenhouse effect and acid rain on the environment.

Analysis of By-Products of N2-SF6 Gas Mixtures Sparked under Inhomogenous Field Conditions [PDF]

, 2004
A vast data on formation of by-products due to arc and spark decomposition of SF6 is available in literature [1–10]. But experimental work relating to N2 - SF6 gas mixtures is limited. In view of increasing application of gas mixtures, it is essential to

Digital Twin of an Electrical Insulation System: Data Communication, Predictive Models and Health Condition

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
Life and reliability models, potentially able to account for any type of stress, even time varying, are developed and their integration in a digital twin is discussed. Algorithms for the dynamic assessment of insulation health condition through diagnostic testing or monitoring, are developed.

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.

Stealthy Deception Attacks Against SCADA Systems

, 2017
SCADA protocols for Industrial Control Systems (ICS) are vulnerable to network attacks such as session hijacking. Hence, research focuses on network anomaly detection based on meta--data (message sizes, timing, command sequence), or on the state values ...
