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

Schweitzer Engineering Laboratories, Inc. (SEL) has announced the immediate availability of arc-flash detection capability in the SEL-751A Feeder Protection Relay, Schweitzer Engineering Laboratories, ...

In the electrical industry, particularly within data center environments, arc flash studies have long been associated with one primary goal: safety. For years, facility owners and managers have ...

In the not-so-distant past, electrical workers routinely racked out breakers in the normal course of their jobs. They did this with little concern or knowledge of the hazards to which they were ...

The comparison figure between no arc-fault state and arc-fault state under various type of loads, ranging from 30 W–60 W. An arc fault is an electrical discharge between two conductors due to poor ...

An arc flash is a sudden discharge of energy, connecting a component with the ground or another voltage phase in the same system through the air. This discharge can result from loose connections, ...

Switchgear comprises electrical disconnect switches, fuses and/or circuit breakers that control, protect and isolate electrical equipment in electrical power systems. A switchgear fault (phase loss, ...

Arc fault detection is a critical issue in modern power and photovoltaic (PV) systems owing to the significant safety risks posed by unintended electrical discharges. These faults, occurring when ...

A quick response to arc faults is essential. However, a lot of available protection equipment is prone to registering accidental trips rather than faults, as well as responding too slowly or ...
