EMFWorkstation Modules

EMFWorkstation Modules

The following modules are part of EMF Workstation 2.51:

EMF Expert Ver 1.0
The EMF Expert System contains an incredible amount of information about all aspects of magnetic fields and management of magnetic fields. It includes tutorials on EMF, transmission line magnetic fields, and distribution line magnetic fields. The tutorials describe topics ranging from residential ground currents to how to manage magnetic fields. A true expert system engine allows the user to ask questions about magnetic fields and then supplies them with answers. For instance you can ask specific questions such as how to measure magnetic fields in schools located in urban settings. The expert system also includes a very comprehensive glossary of EMF related terms.

ENVIRO Ver 3.5
The ENVIRO module calculates lateral profiles for magnetic and electric fields as well as audible noise. The module has the unique ability to calculate induced current on shield wires. This new version has been improved to handle up to 50 conductor bundles (previous version would only accept 24) and it now reads the TLWorkstation version of the input files. The interface has been upgraded and given a 3-D look and it now uses the Microsoft Windows common dialog boxes.

EXPOCALC Ver 3.5
The EXPOCALC module calculates electric and magnetic fields over a 2 dimensional area. It also computes exposure to electric and magnetic fields. It has the unique ability to perform electric field shielding calculations from objects such as transmission towers, buildings and trees. This new version has been improved to handle up to 50 conductor bundles (previous version would only accept 24), the user interface has been upgraded and given a 3-D look and it now uses the Microsoft Windows common dialog boxes.

Power Line Calculator Ver 1.1
The Power Line Calculator (PLC) calculates various electrical characteristics for one, two and three-phase electrical circuits including neutral and ground currents. Symmetric components, power factor, apparent power, reactive power, phase current magnitude and angles, net phase current magnitude and angle, and neutral and ground current magnitude and phase angle are calculated. Given up to six input parameters, WINPLC will determine the remaining system variables. The data from the WINPLC can be dumped into the SUBCALC and RESICALC programs to avoid user input errors.

RESICALC Ver 2.1
RESICALC models the magnetic fields from overhead transmission lines, primary distribution lines, and other user-defined conductors in residential and commercial areas. It also has the unique ability to automatically calculate net currents in the secondary and residential grounding system. The CAD-like graphical user interface lets the user "draw" in the power lines using a mouse. A toolbar provides easy access to the drawing tools. The user-specified data base supports multiple transmission line, distribution line, and grounding conductor configurations. 3-D maps and contour plots provide graphical results of the magnetic field calculations. Improvements over version 2.0 include color coded 3-D maps with contours, multiple levels of un-zoom, copying to the Windows clipboard in metafile format, and support for multiple configuration databases.

SUBCALC Ver 2.0
SUBCALC is similar in operation to RESICALC. However, SUBCALC models the magnetic fields in and around transmission and distribution substations. In addition to transmission lines, primary distribution lines, and underground cables, the user can "draw" in the substation equipment such as buses and circuit breakers. The top and side view perspectives allow drawing of conductors in three dimensions. The program allows the results to be viewed as 3-D and contour maps. Profile plots can also be used which shows the magnitude and phase angle of the magnetic field components along a user-defined traverse. Improvements to version 2.0 include additional equipment models for power transformers, air core reactors/wave traps and capacitor banks. Other improvements include color coded 3-D maps with contours, multiple level un-zoom, support for multiple configuration databases and an edit box for modifying all of the nodes in a bus structure.

Note: All modules in the EMFWorkstation, except for the EMF Expert, are available for download.
