Dynamic State Evaluation Method of Power Transformer Based on Mahalanobis–Taguchi System and Health Index

Energies, 2023
Health status assessment is the key link of transformer-condition-based maintenance. The health status assessment method of power transformers mostly adopts the method based on the health index, which has the problems of multiple parameters of each ...

Maternal coffee intake and the risk of bleeding in early pregnancy: a cross-sectional analysis

BMC Pregnancy and Childbirth, 2020
Background Caffeine can easily cross the placenta, and maternal caffeine intake, thus, has an effect on fetal growth. However, it is still unclear whether coffee consumption is an independent risk factor for bleeding in early pregnancy.

The Proposal of a New Tool for Condition Assessment of Medium Voltage Power Cable Lines

Energies, 2021
A medium voltage (MV) cable network is a substantial component of the distribution network. Present management of this grid segment is mainly based on the failure rate analysis, i.e., a rise in the number and kind of faults on the actual line means that ...
