GaN Power Switch for Power Distribution Protection

IEEE Solid-State Circuits Letters
The electrical power system (EPS) of satellites requires protection devices to isolate failures in short-circuit conditions that can occur in payloads due to various sources, such as debris, mishandling, or radiation.

Analysis on Protection Coordination of OCRs Using Voltage Components for the Application of SFCL in a Power Distribution System with DG

IEEE transactions on applied superconductivity, 2021
As the importance of renewable energy increases, the capacity of dispersed generations (DGs) has increased worldwide. However, the connection of DGs in the power distribution system can cause the fault current to increase as well as malfunction of the ...

Practical Challenges of Inverse and Definite-Time Overcurrent Protection Coordination in Modern Industrial and Commercial Power Distribution System

IEEE transactions on industry applications, 2021
The characteristics of an overcurrent relay (OCR) in protection coordination are determined by adjusting the current and time delay function. This characteristic is adjusted once, fixed, and expected to overcome any disturbances in the system, which ...

Automatic Recloser Adjustment for Power Distribution Systems

IEEE Power & Energy Society General Meeting, 2023
In this paper, a self-adaptive protection system is proposed for adjusting the time dial (TD) of reclosers found in electrical power distribution systems (EPDSs). The selfadjustment is carried out in both phase and ground protection.

Electric Power Distribution System Overvoltage Protection Devices

Elektrichestvo, 2022
Surge protection devices of limiting and combined types used in 0.4 kV electric power distribution networks are described, and results of their experimental studies are presented. The devices have been developed in four earthquake-resistant designs with the use of new-generation nonlinear resistors (varistors) and controlled vacuum arresters.

Power distribution system equipment overvoltage protection

IEEE Transactions on Industry Applications, 1994
Application of surge overvoltage protection devices in general is based upon rule of thumb without the benefit of understanding basic parameters, system components and configuration, and energy content of the surge. This may result in the selection of an inadequate device.

Methodology for Inspection Scheduling in Power Distribution Networks Based on Power Quality Indexes

IEEE Transactions on Power Delivery, 2021
Routine inspection programs are procedures that utilities can use to improve their power quality standards and public perception. However, due to budget restrictions, it is usually not possible to inspect all elements in the whole concession area.
