Proper use of phase-controlled switching technology by controlling the making or breaking
of the circuit breaker (CB) at predetermined phase angles of current or voltage can improve …

Short-circuit fault current suppression is a very important issue in modern large-
interconnected power networks. Conventional short-circuit current limiters, such as …

Faults that occur during the transmission and distribution of energy usually occur in power
transformers. The interruptions in the transformers, the voltage drops, the sudden …

The zero-sequence overcurrent protection always misoperates when the Yg/Yg/D-
connected three-winding high-impedance transformer with high-voltage winding built-in (T …

Transformer magnetizing inrush current can lead false-actions of differential protection and,
reduce transformer lifetime, and send higher harmonics to power grid. The paper deals with …

摘要在对新型换流变压器的保护研究中, 漏感参数的识别尤为重要. 鉴于该换流变压器的特殊
绕组结构, 本文首次推导出以漏感参数的矩阵形式来表征这种结构的特殊性, 并提出一种基于 …

In this article, a new bi-static method for the detection and determination of magnitude and
location of winding radial deformation in power transformers has been proposed. In this …

The transformers used in certain stages of electricity production and distribution are the most
important element due to their high costs and long service life. The most important …

This paper presents a new approach to improve the performance of the power transformer
differential relay. The proposed approach enhance its anti-CT saturation performance during …

This paper introduces the indicators for surge arrester condition assessment based on the
leakage current analysis. Maximum amplitude of fundamental harmonic of the resistive …
