From a safety and security point of view, the electrical energy distribution infrastructure needs to be protected.. In this paper solutions to increase the safety aspects of substation components, power lines and power transformers are discussed. Also security solutions related to perimeter intrusion detection in substations and remote surveillance of power transformer installations are introdu...

the behaviour of power transformers is very like to ideal ones. their characteristic matrices can not be determined directly, because the elements of the characteristic matrices are either close to infinity or zero. on the other hand, strong coupling between two transformer windings causes the determinant of these matrices to become zero. therefore, conversion of these matrices to each other wi...

The estimation of harmonic components of power voltage signals is one of the measurements prescribed by the power quality (PQ) standards (IEC 61000-4-30, 2008). In general, the harmonic components originate from non-linear elements connected to the power system such as non-linear loads (e.g., switched-mode power supplies) or transformers. An example of a distorted voltage measured in an office ...

Reliability and security of power systems, especially in areas prone to earthquakes, depends on the seismic withstand its components interaction these with other elements. All relevant products should be designed tested guarantee high performance. Option which is strongly recommended for qualification shake table test. This way very expensive some cases like transformers impossible due weight s...

in order to reduce the volume and size of distribution power transformer, precise and extended controlling of transformer output, the conventional transformers are replaced by intelligent universal transformers (iuts). in this paper, an iut, typical of iran national grid, with the voltage ratio of 20kv:380 v is designed and simulated. regarding the iut implementation, a cascaded h-bridge invert...

Artificial intelligence is the science of automating intelligent behaviours currently achievable by humans. Power system has grown tremendously over a few decades. As the size and complexity of the power system consisting of generators, transmission lines, power transformers, distribution transformers etc. increases the possibility of inviting faults. The acquisition of data, the processing of ...
