Switchgear and protection lecture 2 type of circuit breakers and applicationsanuphowlader1
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow.
Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

2. Vacuum Circuit Breaker(VCB)
• The technology is suitable for mainly medium voltage
switchgear application.
• Vacuum offers the highest insulating strength. So it has far
superior arc quenching properties than any other medium (oil
in oil CB, SF6 in SF6 circuit breaker).
• The degree of vacuum is in the range from 10^-7 to 10^-5 torr.
3. Principle of Vacuum Circuit Breaker
• When the contacts of the breaker are opened in
the vacuum an arc is produced between the
contacts by the ionization of metal vapors of
contacts.
• However, the arc is quickly extinguished because
the metallic vapors, electrons, and ions produced
during arc rapidly condense on the surfaces of
the circuit breaker contacts, resulting in a quick
recovery of dielectric strength.

5. Construction of Vacuum Circuit
Breaker
• It consists of fixed contact, moving contact and arc shield
mounted inside a vacuum chamber.
• The movable member is connected to the control mechanism
by stainless steel bellows. This enables the permanent sealing
of the vacuum chamber so as to eliminate the possibility
of the leak.
• A glass vessel or ceramic vessel is used as the outer insulating
body.
• The arc shield prevents the deterioration of the internal
dielectric strength by preventing metallic vapors from falling
on the inside surface of the outer insulating cover.
