My name is Tessa Shea and from August 2025 to February 2026 I completed the summer student work placement program at TasNetworks. During this placement I was working in TasNetworks’ Telecommunications division. This department is responsible for maintaining both TasNetworks’ internal telecommunications network and Tasmania’s commercial telecommunications network. The largest project that I worked on during this time was the Wesley Vale Substation Upgrade Project. Telecommunications was one of the departments within TasNetworks working on the construction and installation of primary, civil, and secondary equipment for eight 110kV disconnectors, post insulators, and steel gantries at the Wesley Vale Substation in the north of Tasmania. To complete this work, a planned outage had to be set in place and some of the transmission circuits connected to the Wesley Vale Substation had to be rerouted during the proposed works. I was responsible for writing up the documentation for this project so that the onsite workers could reference it during construction. This project was important to TasNetworks because the disconnector infrastructure at the Wesley Vale substation was out of date and needed to be upgraded. Additionally, these works gave TasNetworks an opportunity to make some other minor alternations to the substation layout to allow for future modifications. This project will have a strong impact on the wider community as the Wesley Vale substation sits on one of the only transmission lines that connects Tasmania’s northern and southern coasts. Its continued operation is important for Tasmania’s telecommunications network, and these upgrades will prevent possible failures in the future. This project was challenging as I had to both write up the documentation for the substation upgrade and propose a new transmission line protection route to use while the outage was happening. This required me to look at the documentation for previous similar projects and use TasNetworks’ network monitoring systems to figure out a viable transmission protection route. This project taught me how multiple departments within a corporation can work together to complete a project, and how the transmission network around Tasmania operates, making it a valuable learning experience during my work placement.
