Currently, most researches on anti-electricity stealing technologies have not combined seasonal power consumption features, social and economic information for electric stealing situational warnings, and cannot effectively solve the problem of large workload and low accuracy in manual anti-electricity stealing monitoring. In addition, they cannot provide reliable technical support for front-line staff of electricity consumption inspection and anti-electricity stealing to accurately and efficiently carry out anti-electricity stealing analysis and investigation work. In view of this situation, this paper proposes a multi-dimensional intelligent deduction and risk early warning evaluation method of electricity stealing situation. © 2020 ACM.

Calcium-magnesium-alumino-silicate（CMAS） corrosion is one of the main failure modes of thermal barrier coatings（TBCs）. Al O-modified YSZ（Y O-stabilised ZrO） coatings can resist it. Here,the effect of the Al O content in YSZ on the resistance of CMAS corrosion was investigated by means of differential scanning calorimetry（DSC）, X-ray diffraction（XRD） and wetting tests. The thermal properties of samples,the Young's modulus and fracture toughness of Al O-modified YSZ were studied by thermal conductivity and Vickers hardness test, respectively. The results demonstrate that when the Al O content is 40 mol%,the Al O-modified YSZ has the best properties to resist CMAS corrosion due to the formation of anorthite which has a high melt point. Furthermore, the phase diagram and phases mole fractions with different Al O content were calculated which match well with the experiments. With the increase of Al O modification content, the thermal conductivity, Young's modulus and fracture toughness of the sample increase.

With the acceleration of the construction of 'Smart Grid' and 'Advanced Metering Infrastructure (AMI)' worldwide, smart energy meter, as a key sensor and measurement point distributed on the network, should have functions such as communication, load control, online upgrade, parameter protection, legal measurement and non-metering partial isolation in addition to basic energy measurement. To this end, China newly revised JJF 1245-2019 standard fully adopts the 'Active Energy Meter' (IR46) formulated by the International Legal Metrology Organization, and stipulates the software and hardware requirements and type certification of the new generation of smart energy meters. This paper first discusses the requirements of a new generation of smart energy meters, compares the differences between IR46 and Chinese energy meter standard systems, introduces some key technologies of smart energy meters that support IR46 standards, and finally expounds the next research direction and application prospects of IR46 smart energy meters. © 2023 IEEE.
