Scheme tends to imply something shady, underhanded, perhaps even illegal. In electrical technology, however, the word simply denotes a plan - a way of doing something. For example, a control scheme is ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

The International Society of Automation (ISA) — the leading professional society for automation — has announced the publication of ISA-TR62443-2-2-2025, Security for Industrial Automation and Control ...

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, ...

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 ...

The Institute of Electrical and Electronics Engineers (IEEE) has published a new standard: IEEE Std. 3004.8-2016, “Recommended Practice for Motor Protection in Industrial and Commercial Power Systems.

Medium-voltage motors are critical to a facility’s power system. Not only are they expensive, but their failure can have crippling, long-lasting impacts on a plant’s operation. As such, properly ...

Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards under the hood and in the cabin. The three major sources of electrical ...

As the electric distribution system transforms into a smarter network, Commonwealth Edison Co.’s distribution automation team has embarked on a step-change journey that will transform distribution ...

Protection against ESD events (commonly referred to as ESD robustness) is an extremely important aspect of integrated circuit (IC) design and verification, including 2.5/3D designs. ESD events cause ...
