How to Apply IEEE Standard 1584.1-2013 Using ETAP Arc Flash Analysis Software

No. of Companies Participating: 12
Date: June 3, 2014




Description:
Practical application of an arc flash hazard analysis using ETAP arc-flash requires the proper determination of the system complexity, number of scenarios to be considered, impact of bolted short-circuit fault currents on protective devices, equipment segmentation considerations, and reporting / labeling guidelines to correctly configure the arc flash program functionalities.

IEEE 1584.1-2013 focuses on these items and this presentation will provide practical application examples and explain which software features need to be configured for different types of systems to follow these guidelines. Those individuals currently planning or performing arc-flash hazard calculations using power system analysis software will benefit by gaining a deeper understanding of the options in the program.

Houston User Group #29 - April 15, 2014 - Cable Thermal Analysis in Underground Raceway Systems

Houston User Group #29 - April 15, 2014 - Cable Thermal Analysis in Underground Raceway Systems Houston User Group #29 - April 15, 2014 - Cable Thermal Analysis in Underground Raceway Systems

 

Cable Thermal Analysis in Underground Raceway Systems (UGS)

No. of Companies Participating: 25
Date: April 15, 2014




Description:
Cable derating analysis is an important part of power system design and analysis. When the goal is to design a new system, ETAP’s UGS module determines the proper size of cables to carry the specified loads. When performing the analysis of an existing system, this cable thermal analysis module examines cable temperatures and determines their ampacity.

Features:
  • Used to compute the effect of duct banks or conduits based on cable steady-state and transient temperatures
  • Allows direct-buried cable systems surrounded with soil as well as cables in conduits surrounded by a raceway (e.g. concrete) with different thermal resistivity than the surrounding soil
  • Neher-McGrath Method
  • IEC 60287 Method
  • Multiple loading conditions
  • Reports and Flags critical & marginal cable temperatures
  • Can handle multi-raceway systems and consider the effect of heat generated by neighboring cables and external heat sources

Houston User Group #28 - February 11, 2014 - ETAP Unbalanced Load Flow

Houston User Group #28 - February 11, 2014 - ETAP Unbalanced Load Flow

 

ETAP Unbalanced Load Flow

No. of Companies Participating: 25
Date: February 11, 2014




Description:
Many applications in industrial and distribution systems require a robust and efficient power flow solution method. These systems have a relatively unbalanced nature.

The ETAP Unbalanced Load Flow Analysis Program calculates the bus voltages, branch power factors, currents, and power flows for individual phases throughout the electric power system. The module allows for swing, voltage regulated, and unregulated power sources with multiple utility and generator connections. It handles both radial and loop systems.

Features:
  • Unbalanced power flow
  • 1-phase & unbalanced 3-phase modeling
  • Open-Delta transformer modeling
  • Alert view to display critical & marginal limit violations
  • Multiple loading conditions
  • Global & individual bus diversity factors
  • Report individual phase & sequence voltage, current, & power

ETAP Arc Flash Analysis Program

Description:
An arc flash incident in an electrical system has the potential for serious injuries and fatal consequences to personnel working on or near energized electrical systems. ETAP Arc Flash is a powerful tool which can be used to perform an incident energy study. The results of which are used to determine the minimum arc rating of the personal protective equipment (PPE); which must be worn by workers when performing hazardous tasks. ETAP Arc Flash can calculate the arcing current, arc fault clearing time, incident energy, and arc flash boundary for labeling the electrical equipment. ETAP Arc Flash is based on the equations and guidelines provided in IEEE 1584 and NFPA 70E standards. The arc flash analysis program is a completely integrated module that solves multiple scenarios including minimum and maximum fault current levels to determine worst-case incident energy. It has many time saving tools, can print thousands of labels in a single click, and can graphically simulate faults and protective device behavior during arc fault conditions.

Features:
  • Arc flash study based on IEEE 1584 2002-2004-2009
  • Arc flash study in compliance with NFPA® 70E 2000, 2004, 2009, 2012
  • 1-phase, 3-phase, AC and DC arc flash analysis (including three DC AF analysis methods)
  • Arc flash in Enclosed and Open air equipment
  • Integrated with ETAP Short Circuit Analysis software ANSI / IEC
  • Integrated with ETAP Star protective device coordination software
  • Work permits and arc flash data sheets, and arc flash labels
  • Arc Flash Result Analyzer
  • Current Limiting Fuse (CLF) modeling
  • PPE Requirements Approval
