Influence of UHV GIL access on transient recovery voltage of circuit breaker
电力工程技术, 2022 The access of ultra high voltage (UHV) gas-insulated transmission line (GIL) affects both the transient recovery voltage (TRV) amplitude and the rate of rise of TRV (RRRV) of circuit breakers,which may endanger the breaking capacity of circuit breakers ...

Field Analysis of SF(6) Gas Insulated Cables and Its Application to Spacer Design
, 1974 This paper describes the spacer design for SF(6) gas insulated cables. The maximum electric stress within the cable is calculated by a numerical method, and it is recognized that the breakdown voltage depends linearly on the calculated values.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Characterizing the Steady-State Performance of AC Lines Through a Dimensionless Universal Model
IEEE Access, 2022 This paper revisits the AC power line model. Based solely on three dimensionless parameters, a universal electrical model is first developed, which is valid for any kind of power line (overhead, underground/submarine or gas insulated), irrespective of ...

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
