Effect of Unit Cell Topology on Dielectric Properties of Periodic Lattice Materials Used for Functionally Graded Insulation

High Voltage, EarlyView.
ABSTRACT Periodic lattice material (PLM) is an innovative material system capable of rapidly and efficiently constructing functionally graded materials (FGMs). Among various PLM structures, triply periodic minimal surfaces (TPMS) exhibit numerous advantages, making TPMS‐based lattice materials a potential candidate to electrical FGMs.

Micro Partial Discharge Characteristics of SF6 Under DC Voltage

High Voltage, EarlyView.
ABSTRACT In gas‐insulated high‐voltage direct current (HVDC) devices, micro partial discharges (PD) caused by micro‐protrusions or surface roughness on conductors or enclosures may not cause immediate insulation system failure due to their weak discharge intensity.

Post‐Arc Transient Dielectric Recovery Characteristics of Vacuum Interrupter in the Large‐Capacity Generator Circuit Breaker

High Voltage, EarlyView.
ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)
