What Causes Arc Flash? Electrical Arc Blast Explained | Fluke
One of the major causes of arc flash is voltage transients (spikes), resulting from switching reactive loads or lightning strikes. The transient might last only microseconds, but it can carry thousands of amps of energy.
Understanding the arc flash boundary - Fluke Corporation
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 - Fluke Corporation
Reduce the risk of arc-flash and electrocution; Decrease maintenance costs and reduce downtime by making critical power quality and energy measurements without opening the panel door; Enabling logging and monitoring at any time—without disrupting operations; Increase measurement efficiency and reduce the need for full arc-flash PPE; 2.
Main causes and types of partial discharge - Fluke Corporation
Typically caused by a minor defect and resulting in thousands of mini repetitive discharges, the partial discharge propagates and grows over time. Eventually, this can cause catastrophic failures resulting equipment failure and dangerous arc flashes. Of primary concern for most is safety.
Top 10 Changes to 2018 NFPA 70E Safety Standards for Electricians
Fluke outlines important changes in the 2018 NFPA 70E standard for electrical safety in the workplace, including a new table on estimating arc flash occurrence and corresponding PPE requirements; dc voltage shock threshold; CPR and first aid training and more.

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.
Top 3 Solar Panel Safety Precautions | Fluke - Fluke Corporation
An arc flash releases hot gases and concentrated radiant energy up to four times the temperature of the sun’s surface—as high as 35,000° F (~19,500° C). It occurs when a large amount of energy is available to an arc fault, in both DC and AC conductors.
How to find and repair ground faults in solar PV systems
A clear, consistent approach to finding and diagnosing such faults can help you repair them reliably and efficiently whenever they occur. Learn to identify and correct ground faults in solar PV arrays using various tools and methods for utility-scale and commercial PV systems.
Guide to Assessing Risk: Energized Electrical Work Permits
This section directs electrical workers to place electrical conductors and circuit parts into an electrically safe work condition if they are within the restricted approach boundary or the arc flash boundary when interacting with equipment in a manner that could cause failure.
