Abstract:

Safety of human life is of a paramount importance. In high current switching system, switch gear protects electrical circuit. However there is need to provide confidence to working engineers during installation work on high voltage installations. To prevent accidental switching on of switch gear by unauthorized workforce, this paper proposed a more life secured switching password-enabled device that strengthen working confidence and inactivate unauthorized person from hazardous switching of electrical power installation without the notice of field working engineers.

Electrical energy is a primary human requirement for continuously operating electronic devices. However, nonrenewable electrical energy is becoming increasingly scarce. As a backup power source, regenerative energy sources are an option. Because the conventional power grid transfer system takes a relatively long time, the application of a control system on the power grid transfer automatically can maximize efficiency, safety, and accuracy. In this study, an ATS system was developed using the electrical grid switching method for 300ms, 600ms, and 1000ms, as well as IoT to optimize the ATS manua

Synchro-check (SC) relays are devices that control synchronization between different fragments of power system networks. Synchronism is monitored by controlling the voltage amplitude, angle, and frequency differences. The goal of monitoring is to avoid dangerous transients after the circuit breaker (CB) closing, which occur when the differences between the voltage, angle, and frequency at both sides of the CB are above the threshold. Although the idea of SC is straightforward, one needs to realize that blocking of the CB closing may cause even more severe issues, i.e., the deterioration of pow

Abstract:

Overvoltage is a voltage that can only be held for a very limited time. Overvoltage that occurs for a time that exceeds the equipment's capacity limit will damage the equipment connected to the network that is subjected to overvoltage. Lightning overvoltage is a periodic overvoltage caused by external overvoltage, both direct and indirect strikes. Lightning overvoltage only lasts a very short time but has a voltage that is so high that it exceeds the operating voltage of the equipment so it is potentially very damaging.

Abstract:

Leakage current is an issue that often causes problems in transformerless grid-connected PV inverters, such as electromagnetic interference, which is conducted or radiated and derates the quality of power injected into the grid. It can also lead to electrical safety problems, impair the performance of other equipment nearby, and thus make the generation system unavailable. Therefore, mitigation procedures for the leakage current in transformerless grid-connected PV inverters are essential to ensure system efficiency and safety. In this sense, a new single-phase grid-connected transformerless i

Day by day, the need for renewable fuel has increased to reduce the usage of non-renewable fuels and also to provide adequate fuel for vehicle use worldwide. Organic fuels that can be derived from different sources are renewable fuels, of which oil extracted from algae cells can also be used as a biofuel. Algae oil extraction can be achieved by applying a Pulsed Electric Field across the algae cell to rupture its membrane and to remove oil. A Pulse Generator, capable of carrying out this operation, although in existence, has some drawbacks including lack of versatility, performance and reliabi

In addition, networks which are fed by batteries and renewable sources such as solar panels, and wind turbines are suffering from conversion-based power losses.

The hydraulic system is used as the auxiliary power source of the power system giving full play to the advantages of the hydraulic system and the electric system.

Abstract:

Induction heating (IH) technology is widely recognized and utilized in residential applications due to its high efficiency and safe operating characteristics. Resonant inverter circuits are widely used in IH systems because of their high efficiency and ability to perform soft switching. Among the various resonant inverters used in IH systems, the single-switch quasi-resonant (SSQR) inverter topology is typically preferred for low-cost and low-output-power applications. Despite its cost advantage, the SSQR topology has a relatively narrow soft-switching range, which can be unstable depending on

A control strategy that combines fuzzy control and switching control is proposed, taking into account factors that affect the fuel cell’s durability and the supercapacitor park’s safety. To smooth the output power of fuel cells under frequent variable load conditions, a moving average filtering algorithm has been added.

Abstract:

Electrical energy transmission plays an important role as a means of distributing electrical energy from generation to distribution and consumers. During the process of distributing electrical energy, disturbances such as short circuits often occur. Therefore, there needs to be safeguards so that the distribution process runs well. One of the safety equipment in the main substation is the circuit breaker. Circuit breaker is a mechanical switch or switching equipment that can close, transmit or disconnect the load current under normal conditions or under abnormal conditions such as a short circ
