Group Assignment 1
This assignment will require using Ansys Maxwell software. It is an electromagnetic field solver which solves static, frequency-domain and time-varying magnetic and electric fields. To familiarise yourself with the software, you can watch a video available on Moodle from a related course ELEC4611 on electric field analysis using the same software.
There are several ways for you to get access to this software:
1. You can remote access the software. Go to myAccess, install Citrix Workspace, run Ansys Electronics Desktop 2023 R2 application, select Maxwell tab and click Maxwell 2D.
2. Or you can go and use the software already installed in the computer labs (rooms 202 and 217 in the Electrical Engineering Building).
3. Or you can download the free Ansys Electronics Desktop Student 2024 R2 from this link:

The figure above shows the cross section of an 11kV (line-line) single-core XLPE cable. The inner conductor has a radius of a = 5mm , the outer radius of the insulation is b = 13mm . The relative permittivity of XLPE is 2.3. Use Ansys Maxwell 2D to obtain the electric field intensity in the insulation for the following scenarios:
1. Plot the electric field distribution along path #2.
2. There is an air void trapped inside the insulation where c = 7.5mm . The void is actually spherical of 1mm in diameter, but we will consider it as cylindrical so that 2D analysis is applicable. Plot the electric field distribution along path #1.
3. As in case 2 above but the void is now touching the inner conductor, i.e., c = 5.5mm .
4. As in case 2 above but the void diameter is 1.2mm.
5. As in case 2 above but the void diameter is 0.8mm.
6. As in case 2 above but with presence of a second void of same size, same radial direction as the first void and touching the inner conductor, i.e., its radial distance is c2 = 5.5mm .
7. As in case 6 above but the second void is now touching the first void, i.e., c2 = 6.5mm .
Each group is to submit a written report. Clearly describe the various steps taken to construct the structure, how to run the simulations and get high-resolution results. Show the field plots, comment on the results and where possible, compare with results from analytical solution.
