Arc flash vs arc blast

Arc flash vs arc blast. When an arc fault occurs, the result is a massive electrical explosion. The light and heat emitted by the explosion is known as the arc flash, and the pressure wave is known as the arc blast.

Arc flash protection with thermal imaging

Understand what the NFPA 70E standards for arc flash PPE assessment means for thermographers using thermal imaging camera.

Understanding the arc flash boundary

The arc flash boundary is the minimum “safe” distance from exposed energized conductors or circuit parts that has the potential for an arc flash. The required arc-rated clothing and PPE increases rapidly as a worker approaches the potential source of an arc flash

Top 5 safety tools for preventing arc flash

Limiting workers’ exposure to electrical hazards like arc flash or electrocution is a solid foundation for any electrical safety program. Combine that mindset with the right non-contact tools and more electrical workers will be kept out of harm’s way.

Electrical safety standards

To meet the demands of today’s high-energy, high-hazard workplace, quality manufacturers like Fluke continue to improve their test instruments to make them safer and more reliable.

Four Myths About Electrical Safety That May Surprise You

Following electrical safety regulations in industrial plants is critical. But myths about electrical safety are rampant. Understand the facts vs myths about working in energized systems.

聰明人測試電力時常犯的10個低級錯誤

任何以與電打交道為生的人，都會迅速對任何哪怕只有一絲可能"帶電"的東西建立起應有的敬畏之心。然而，按時完成工作的壓力，或是讓關鍵設備恢復運行的任務，都可能導致即使是經(jīng)驗最豐富的電工也出現(xiàn)疏忽和不尋常的錯誤。

Curb Explosive Potential with Intrinsically Safe Tools

Curb explosive potential with intrinsically safe tools. For those who work in industries where flammable materials are present—such as petrochemical and pharmaceutical plants, oil platforms, refineries, pipelines, and mining—the potential for an explosion is a daily reality. All it takes is a flammable material coming into contact with air and an ignition source.

How infrared cameras help you stay safe on the job

If you troubleshoot or maintain equipment in an industrial setting, staying safe depends partly on the environment and partly on you.

How to Use TwistGuard Test Leads for Maximum Safety

Fluke TwistGuard? Test Leads:safer, tougher, more versatile

How to Test Multimeter Test Leads for Accuracy and Safety

Checking your test leads to make sure they are in good condition and rated for the job at hand is the best insurance for accuracy and safety

Checking Grounding Electrode Impedance for Commercial, Industrial, and Residential Buildings

Solid ground: Increasing parallel conductor ampacity

The most popular reason for paralleling conductors is to provide higher ampacity than a single conductor can provide. "In a typical building design, the largest conductors are usually 500 kcmil or 600 kcmil". "And many electrical contractors will actually object to 600 kcmil. If ampacity above 400 A is necessary, using parallel conductors is the only reasonable solution.

Grounding separately derived systems

As I promised in my last column, this "Solid Ground" column deals with transformers and grounding. Let's start by addressing some definitions. Opinions differ on the "official" definition of "distribution" transformer.

Chasing "ghost" trips in GFCI-protected circuits

This issue of "Solid Ground" talks about ground fault circuit interrupters (GFCIs), why they are necessary, and how to troubleshoot GFCI-protected circuits.
