ARCAD Arc Flash Analysis

ARCAD is pleased to introduce the new ARC FLASH ANALYTIC ( AFA V3.0 ) software program for arc flash and shock hazard analysis. AFA V3.0 has been developed based on NFPA 70E and IEEE 1584 as an easy to use and comprehensive tool for calculating arc incident energy, flash protection boundary, determining limited, restricted, prohibited shock approach boundaries and risk category required by N.E.C and OSHA when work is to be performed on or near the energized equipment.


Results You Can Trust

Every release of AFA is verified and validated against established programs and hand calculations in order to ensure its technical accuracy. Each release of AFA undergoes a complete verification process using hundreds of test cases.

AFA V3.0 Key Features

1) IEEE 1584 EMPIRICALLY DERIVED MODEL AND LEE METHOD. Applicable for systems with:
  • Voltages in the range of 208V to 46kV
  • Bolted fault currents in the range of 700A to 106kA
  • Switchgears, MCC, panels, cables and arc in open air
2) IEEE 1584 FUSE EQUATIONS. Applicable for systems protected by current limiting Class RK1 and Class L fuses.

3) IEEE 1584 LOW VOLTAGE CIRCUIT BREAKER EQUATIONS. Applicable for systems protected by:

  • Molded case, insulated case (MCCB & ICCB) circuit breakers,
  • LVPCB low voltage power circuit breakers

AFA V3.0 Key Capabilities

1) Determine
  • arcing current
  • incident energy
  • flash protection boundary
  • limited, restricted and prohibited shock approach boundaries
  • initial arc pressure
  • arc TNT equivalent
  • risk category
  • typical clothing system
2) Save results for future reference or printing.

3) Perform analysis using metric (mm, Joules, kg ) or imperial units (inches, calories, lb ).

4) Create customized color or black-and-white warning labels in English, French and Spanish.

Calculator-style interface makes complex calculations easy to understand. Detailed procedure for IEEE 1584 based arc flash calculations has been included in the calculator. An effective arc flash safety program must be designed on a reliable foundation. Arc flash studies must be performed by qualified persons using a quality analysis tool which provide accurate results that you can trust and rely on.

Don't spend a fortune on expensive software for arc flash analysis. Save your money, purchase Arc Flash Analytic and generate arc flash warning labels to meet OSHA and NFPA 70E requirements.

Arc Flash Hazard Calculator

Arc-Flash-Analytic v 2.0 calculates the incident energy and arc flash boundary for any point in a power system.

Arc-Flash-Analytic v 2.0 software tool has been developed based on IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations as an easy to use and comprehensive instrument for calculating arc incident energy, flash protection boundary and risk category required by N.E.C and OSHA when work is to be performed on or near the energized equipment.

The IEEE 1584 empirically derived model was chosen for the analyzing arc flash faults since the model is capable to accurately account for variety of setup parameters: open and box equipment configurations, grounding of all types and ungrounded, gap between conductors of 3 to 152 mm, bolted fault currents in the range of 700A to 106kA, system voltages in the range of 208V to 15kV, and working distances. Reference data listing most typical configurations and detailed procedure for IEEE 1584 based arc flash calculations has been included in the calculator.

The calculator takes equipment configuration, gap between electrodes, grounding type, short circuit fault current value and system voltage on input, and determines arcing fault current at potential point of fault. Next, the incident energy, flash protection boundary and level of personnel protective equipment are determined based on equipment configuration, arc duration and working distance.

For protective devices operating in the steep portion of their time-current curves, a small change in current causes a big change in operating time. Incident energy is linear with time, so arc current variation may have a big effect on incident energy. The IEEE 1584 solution is to make two arc current and energy calculations: one using the calculated expected arc current and one using a reduced arc current that is 15% lower.

The calculator makes possible both calculations for each case considered. The IEEE 1584 procedure requires that an operating time be determined for both the expected arc current and the reduced arc current. Incident energy is calculated for both sets of arc currents and operating times and the larger incident energy is taken as the model result. This solution was developed by comparing the results of arc current calculations using the best available arc current equation with actual measured arc current in the test database. The calculator predicts arcing fault current for a given configuration and bolted fault short circuit current. It also predicts bolted fault current required to cause 15% reduction of the predicted arcing current for the given configuration.

Benefits:

  • Calculator-style interface makes complex calculations easy to understand.
  • Provide a safer working environment by specifying the proper level of PPE. Wearing inadequate clothing is dangerous for obvious reasons, but wearing too much clothing is dangerous due to limited mobility and visibility.
  • Design safer power systems while insuring compliance with NEC 110.16, OSHA, NFPA 70E and IEEE 1584 standards.
  • Avoid potential fines, lost productivity, and increased insurance and litigation costs.
  • Save time by generating arc flash warning labels in electronic .JPG and .BMP formats
  • Customize labels by selecting and adding information displayed on them.
  • Save results in generic text format for future reference or printing with one button click.
  • Perform analysis using metric (mm, Joules ), imperial units (inches, calories ), or even a mix of both

Arc Flash Calculator now available online

We have developed an easy-to-use and comprehensive free online tool for calculating arc incident energy, flash protection boundary and risk category required by NEC and CEC when work is to be performed on or near the energized equipment. The calculator takes equipment configuration, gap between electrodes, grounding type, short circuit fault current value and system voltage on input, determines arcing fault current, calculates incident energy, flash protection boundary, hazard / risk level at the potential point of fault and creates detailed warning label.

Error propagation analysis - very important but widely ignored issue,

The ArcAd tool performs more than just tedious calculations. We have implemented a parameter of tolerances to our service, which has an effect on final results within the analysis. Many other procedures do not take into account room for error, which can distort final values. A lack of understanding of basic error analysis has led some very bright scientists and engineers to make some incredible blunders. ArcAd's short circuit online calculator features input data analysis and hard coded error propagation rules ensuring that the results are not more precise than justified by the accuracy of input data.

Typical commercial software has more interfaces and graphic content, which make them more appealing and expensive. ArcAd's on-line tool is user friendly, performs error propagation analysis - very important but widely ignored issue, and is offered at a reasonable price. We strongly believe that if a resulting margin of error can't be quantified, then it's not engineering, but only a guess. As far as we are aware, none of the available competing products performs proper error analysis. It wouldn't be a problem if most accurate system equipment data were available. Experience shows that by far most real world studies are built upon approximate and therefore more or less accurate input data. The concept of precision is very important indeed and can impact results in surprising ways.

What are the major service benefits for the consumer offered by ArcAd ?

We offer online tool for fault current analysis. As far as we are aware, none of the competition offers similar service online. Advantages include:

* Input data error propagation analysis
* No need for software installation
* No risk associated with virus threat
* System can be accessed, operated and shared from anywhere, anytime, on any platform connected to the Internet
* Access to most recent services and updates
* Most competitive price in the industry
* Routine data backup
