The new adiabatic feature available in ThermNet and can be used for both coupled MagNet and ElecNet simulations. The adiabatic features models sudden and rapid heating, such as lightning strikes.
Version 7.2 also introduces the multicore feature to post-processing for even faster results and transparency for improved visualizations.
MagNet, ElecNet and ThermNet v7.2 are now available. Maintained clients can visit support.infolytica.com to download the software or read the release notes for full details.
To request an evaluation, live demo or pricing information, please contact your local Infolytica Corporation representative.
Surge arresters are used in a number of industries as protective devices against a variety of electrical events such as high voltage lightning impulse. The design choices of various materials and components for lightning arresters may depend on their thermal characteristics among many other factors. To demonstrate this, the thermal analysis of a 330 KV metal oxide arrester is considered in this example. The adiabatic heating of the varistors due to a lightning strike and the subsequent temperature distribution in the device as a function of time are presented here
With their new coupling feature, the power loss data from ElecNet can be used as a heat source in ThermNet, allowing users to determine the impact of temperature changes on the overall design and performance.
This new capability is just one amongst the many existing that has made ElecNet a well-known and trusted electric field simulation package, offering engineers an accurate and fast design tool.
This free one hour event will cover the new features available in this latest release. The demonstration will focus on using ElecNet and ThermNet to simulate a surge arrestor. You can also put forth your own questions to our application specialist.

The design and modeling of dual fed induction generators is considered in this tutorial. The topic will be covered by using examples that are focused primarily for wind power generation applications. The tutorial will begin with an overview of such systems and component identification. The design and modeling methodologies and challenges of various components will be discussed then. This will be followed by discussions on the design of induction generators and their field oriented control strategies. Topics covered will include design strategy for initial design (sizing, material and winding designs), load point analysis, and machine performance etc. Multi-physics aspect (electromagnetic, thermal, and mechanical) of the design algorithms will also be discussed. Aside from generator design, there will also be some general discussions on inverter topology and simulation specific to such devices. Modern computer aided design software will be used to illustrate the various design and simulation strategies related to such systems. As well, a literature review will accompany the presentation to highlight the state-of-the-art of such systems.
