aIn the case of utility types of power systems, it has been found that high voltage dc transmission (HVDC) lines are economical only when very long distances (of the order of thousands of miles) are involved, but for short and moderate distances, ac systems are still considered to be bette...
GTO and GCT properties are combined in IGCTs, which also include built-in gate-commutation circuitry and improved switching capabilities. They are employed in high-power applications such as high-voltage direct current (HVDC) systems, renewable energy systems, andindustrial motors. Emitter Turn OFF ...
Although HVDC transmission has exploited line-commutated power electronics for the past three decades, it is the 1990s which have witnessed the commissioning of self- commutated power electronics at the transmission level. Developments in semiconductors and their packaging technology will drive power ...

Power transformers are essential for efficient and reliable power transmission and distribution. They can reduce power losses, improve voltage regulation, and increase system stability and reliability. HVDC Transformers HVDC transformers convert AC power to DC power for use in high-voltagedirect currentsy...
This paper presents a review on the applications of various types of circuit breakers (CB) used in electric power transmission and distribution. Circuit breakers are majorly classified under direct current (DC) or alternating current (AC) system. It shows that the most suitable way of classifying...
Multi-objective optimization operation with corrective control actions for meshed AC/DC grids including multi-terminal VSC-HVDC This paper presents a multi-objective optimal operation of meshed AC/DC power grids including multi-terminal voltage-source-converter-based high-voltage di...

The arrangement of these devices can be done on the towers, transmission poles and buildings to give a secure lane to the voltage & discharging current. Here these can be occurred during the strokes of lightning toward the ground to defend the system from the induced problems of lightning. ...
Substations which are designed for improving the power factor of the electric supply are called power factor correction substations. These substations are generally installed at the receiving end of the transmission lines. In these substations, the capacitor banks or synchronous condensers are the main ...
an application of superconducting fault current limiter (SFCL) is proposed to limit the fault current that occurs in power system, SFCL is a device that uses superconductors to instantaneously limit or reduce unanticipated electrical surges that may occur on utility distribution and transmission networks...
