Title

An Electrostatic Simulation of a Surge Arrester

Based on a paper from the International Electrotechnical Commission: this surge arrester has 2 grading rings. It is formed of 2 electrodes: one at the top formed by a conducting metal rod and 2 conducting metal grading rings, and the other at the bottom forming the pedestal of the surge arrester. The ElecNet simulation presented here was compared to results provided by the IEC.

Electric Field Due to a Pulsed Voltage Source

The 3D transient electric field simulation of a simple copper strip on a dielectric layer over a ground plane is described in this example. The analysis is in 3D since the copper strip is short and there is fringing of the electric field at the end of the strip.

Electric Field Transient Analysis of a Conductive Shield

Transient phenomena may be present in many devices containing components that are kept at a fixed voltage. Before steady state is reached, it may be necessary to model and understand the nature of the transients. Using ElecNet, it is possible to model and capture this phenomenon. Here, using a three dimensional, axis-symmetric model of a conductive shield, the transient aspect of the device is captured.

Simulating a Charged Particle Entering a Quadrupole Ion Trap

Using ElecNet and the Trajectory Evaluator add-on, the trajectories of charged particles entering a Quadrupole Ion Trap can be simulated. The results presented are based on a particle with an electric charge (of value -1.6e-29) being placed at the center of the ion trap while the side electrode is subjected to a frequency of 100 Hz.

Simulating Particle Filtration with an Electrostatic Precipitator

The path of particles entering an electrostatic precipitator and their collision with the collection plates are tracked, simulating an air filtration process. Voltage is applied to the collection plates in order to ionize the gaz around each electrode.

Thermal Characteristics of a 330 KV Surge Arrester

The thermal analysis of a 330 KV metal oxide lightning 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 is presented.

Transformer bushings

In this example, the transformer busing consists of nine foils of various lengths that are placed inside of epoxy-resin impregnated paper (ERIP) at specific locations in order to minimize the maximum electric field, E.
