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.

10 dumb things smart people do when testing electricity

Anyone who makes their living by working with electricity quickly develops a healthy respect for anything with even a remote chance of being "live." Yet the pressures of the getting a job done on time or getting a mission-critical piece of equipment back on line can result in carelessness and uncharacteristic mistakes by even the most seasoned electrician.

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.
