IEEE 1584-2018 – In Depth Arc Flash Calculations Using Mathcad Express & Etap 19.0

arc-flash-hazard-test-on-PPE

Previously, we have written a detailed blog on the major changes in the newly approved IEEE 1584-2018 standard. If you haven't checked it out, please click here!

Now, in this blog we will explain the arc flash calculations which are used in the official standard of IEEE 1584-2018 in a very simple and intuitive manner.

Many Arc flash softwares including:

Performs Arc flash calculations in the back end and gives only the final result in the form of Tables, report and Arc flash labels. In this way, user will not be able to grasp the idea of manual calculations, but as a Power Systems Engineer or Protection engineer, you must know about the manual calculations, on which the whole arc flash study calculations rely or based upon.

Plugging Two Extension Cords Together is Dangerous! Here’s Why Can’t You Attach Two.

extension_cord_dangerous_to_plugin_together

Extension cords enable us to deliver power where needed. However, an extension cord is just a temporary solution, and should not be used as a long-term extension of your household's electrical system.

Extension cords are designed to carry a certain level of current over a fixed distance which is the length of the cord. Once you have two identical extension leads connected in series, one after the other, the extension cord's resistance effectively increases. This results in greater heating of the cord and possible damage to the insulation, which can be the source of fires and electrical shock.

Arc Rated Vs. Flame Resistant Clothing – Important Difference Need To Know

AR_FR_clothing

When the National Fire Protection Association (NFPA) replaced the term "Flame Resistance (FR)" with "Arc-Rated (AR)" in its 2012 edition of the NFPA 70E, it stirred confusion among many.

What was the difference between FR and AR?

The short answer: 

"All arc-rated clothing is flame resistant, but not all flame resistant clothing is arc-rated"

(Selection Guide) - How to Select the Right Fuse for Power Systems Protection

selection-of-right-fuse-for-power-system-protection

"A fuse is essentially a metal wire or strip that heats up and melts when too much current flows through it, thereby opening the circuit and interrupting the current flow."

In order to select the right fuse for a given system, it is imperative that the various fuse parameters are thoroughly understood. Hence, this guide will first define each contributing factor and then explain how it is used by engineers and circuit designers to choose the best device for circuit protection.

The factors to be considered when selecting a fuse are as follows:

NFPA 70E 2018 – An Overview of 4 Different Arc Flash PPE Categories

personal-protective-equipment

An unfortunate truth about Arc Flash incidents is that they can occur regardless of training. Without proper protective measures, workers are left exposed to dangerous conditions and have to suffer the consequences. Every year, more than 2,000 people are admitted to burn centers with severe arc-flash burns.

While arc-flash cannot be completely eliminated, there are steps we can take to prevent it. The single most important measure is placing the equipment in a "Safe Working Conditions" If it is more dangerous to turn the equipment off, workers should wear appropriate Personal Protective Equipment (PPE).
