A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

Ground fault protection is a cornerstone in ensuring the safety and operational reliability of modern power systems. Ground faults, which occur when an unintended electrical path connects a live ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

Large-scale infrastructure projects, interconnection schemes, and renewable energy developments continue to shape the ...

Out-of-step protection is a critical component of modern power system protection schemes—its importance has grown significantly with the increasing penetration of inverter-based resources (IBRs) and ...

The rate of transient occurrences varies with every power system. Recent studies show that surges of 1kV or less are common — whereas 3kV surges are rare. Protecting against more frequent (internally ...

Benefits of an e-fuse solution. Optimal voltage range for e-fuse applications. Target applications for e-fuse devices. The trend toward higher bus voltages creates the need for a robust circuit ...

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and ...

A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas ...
