Development of online monitor for substation 10 kV MOA

open access: yesThe Journal of Engineering, 2019
Metal oxide arresters (MOA) are widely used for over-voltage protection of power facilities in 10 kV distribution networks, and it is hard to determine the failure ones. This study presented an online monitor for 10 kV MOA used in substation.

An Improved Method for Calculating the Radiative Cooling Heat Dissipation Power of an Oil‐Natural‐Air‐Natural Transformer

open access: yesHigh Voltage, EarlyView.
ABSTRACT Radiative cooling holds potential for outdoor transformers in operation due to its zero‐energy consumption and high adaptability and has demonstrated effective heat dissipation in simulations of small distribution transformers. Accurate calculation of the transformer temperature rise and the radiative cooling effect is crucial for practical ...
