Software suite for modeling and calculating magnetic fields from electrical
is a suite of software programs designed to calculate magnetic and electric
fields from electrical facilities and other sources, such as transmission and
distribution lines, substations, and common residences. The software is owned by
the Electric Power Research Institute (EPRI), and Enertech has a
commercialization license to make available this software to non-utility
companies, firms, and organizations. The software suite includes:
The EMF Expert - Magnetic field tutorial materials,
including field management,
transmission and distribution line magnetic fields,
ground currents, and glossary of EMF terminology.
ENVIRO - Electric and magnetic field lateral profile
calculations from power lines
(as well as audible noise), with a capacity of up to
conductor bundles and calculation of induced
currents on shield
SUBCALC - Magnetic field modeling of electrical
facilities such as substations,
including transmission lines, primary distribution
underground cables and substation equipment such as
circuit breakers, power transformers, air core
RESICALC - Magnetic field computer modeling of
residential environments due
to the presence of overhead transmission and
allows user-defined conductors, and automatically
currents within secondary and residential grounding
EXPOCALC - Electric and magnetic field exposure
calculations from power lines
based upon time and activity factors within
designated areas, with
a capacity of up to 50 different conductor bundles
of electric field shielding from objects
(transmission line towers,
buildings, and trees).
PowerLine Calculator - Computes electrical
quantities associated with power
lines, such as phase current magnitude and angles,
power factor, apparent and reactive power, neutral
ground current magnitude and phase angles, etc.
is not authorized to sell the EMFWorkstation to any electric utility.
Organizations that are eligible for
EPRI membership (which currently includes both domestic and
international electric utilities) can obtain the workstation for free by joining
the EMF Management Target. Current members of EPRI's EMF Management Target can
order free copies of the EMFWorkstation by contacting the Electric Power
Software Center. All other interested agencies (government, education, or
engineering/consulting) should contact EMDEX LLC.

lock has been integrated into the EMF Workstation. The software will run in
a demo mode (can't perform calculations or save files to disk) until it has
been properly registered with EPRI and a valid unlock code has been entered.
code will provide access to the software for the remainder of the calendar
year. It will automatically "time-out" on December 31 of each year, at which
time you must call in and re-register the software for another year of use.
The software will revert back to demo mode until another valid unlock code
lock also prevents the software from being installed on multiple systems
without calling in for an unlock code. EPRI is requiring this registration
so it will have a record of end users for the EMF Workstation. For EPRI
utility members, contact the EPSC after receiving and installing the
software to obtain an unlock code. For non-members, please contact EMDEX
product incorporates technology developed for the Electric Power Industry
under the sponsorship of EPRI, the Electric Power Research Institute.
