Apple could benefit from a new wave of NFC technology upgrades after the NFC Forum this week published a roadmap outlining ...

Abstract: The increasing digitalization of modern substations has improved operational efficiency while simultaneously exposing protection schemes in digital substations to sophisticated cyber threats ...

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

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess the integrity of insulation in motors, cables, transformers, and other ...

Industry Trends and Growing Demand for Primary Current Injection Testing Power systems worldwide are undergoing transformation. Aging infrastructure in many regions requires refurbishment and ...

Discover how today’s digital protective relays outperform legacy electromechanical systems in reliability, diagnostics, and overall availability. Modern digital protective relays are redefining ...

At 5:20 PM on November 9, 1965, the Tuesday rush hour was in full bloom outside the studios of WABC in Manhattan’s Upper West Side. The drive-time DJ was Big Dan Ingram, who had just dropped the ...

Testing relays is both an art and a science. As relay technicians inevitably learn in the field, pure theory-based understanding of protective relays is not nearly enough for the real-world situations ...

Abstract: Grid-forming (GFM) inverters can significantly alter the fault characteristics of power systems, posing challenges to the proper function of protective relays for transmission lines. This ...
