Transgrid has undertaken extensive aerial inspections along 13,000km of transmission lines In preparation for bushfire season, and to ensure its adherence to fire mitigation measures. Transgrid conducted its bushfire safety program from February to November 2022 to ensure safe vegetation clearance and the condition of transmission assets. The assessments, which included 3D laser scanning, aerial imagery analysis, and helicopter inspections, [...]
Arriving in Port Kembla, the transformers will be instrumental in delivering Transgrid’s $1.8 billion EnergyConnect interconnector. The main tanks of the transformers, weighing more than 118 tonnes each, as well as components and accessories in 52 crates, were unloaded at Port Kembla after being shipped from China. The transformers will be transported by heavy road transport vehicles to the project [...]
By Brett Redman, CEO, Transgrid We must act now to accelerate the timeline for when renewables can deliver cheaper, cleaner and more reliable energy to homes and businesses. There will be no transition without transmission and that is why Transgrid is building the future grid, made up of major transmission projects which will enable the sharing of clean energy across [...]
Quick, effective closed transition switching is crucial for any site or application that relies on a backup power supply from a generator to ensure power is not lost. A closed transition transfer switch is designed to seamlessly switch between two power supplies, often using make-before-break switches, and a controller that senses if the supplies are synchronised, before allowing switching. Closed [...]
Across all industries, sustainability objectives are put in place to progressively increase the efficiency of operations, with ambitious targets set to significantly reduce greenhouse gas emissions. To meet the targets, all parts of the operations must contribute and carefully review all opportunities to reduce energy consumption. It was never really considered as a realistic possibility that low-voltage switchgear designs could also contribute to these objectives. However, as switchgear generates [...]
Project EnergyConnect, once approved and constructed, will directly link the energy networks of South Australia and New South Wales for the first time. The largest electricity interconnector project to date in Australia, EnergyConnect is a cornerstone of the Australian Energy Market Operator’s (AEMO) 2020 Integrated System Plan (ISP). The ISP is a roadmap to ensure Australia has a resilient and [...]
The consequences of air circuit breaker (ACB) failure can be financially costly and potentially dangerous to personnel. Retrofit solutions can help address this issue by allowing end users to modernise their ACBs with minimal downtime. Retrofitting of ACBs is typically 80 per cent cheaper than replacing an entire switchboard, with the key components of the system able to be quickly [...]
Before Australia officially committed to a target of net-zero carbon emissions by 2050, and a world away from the COP26 conference in Scotland, the real work of reducing Australia’s greenhouse gas emissions was already well underway. Four years ago, State Government-owned energy utility Horizon Power commenced a series of Distributed Energy Resource (DER) trials in the coastal Gascoyne- Midwest town [...]
ElectraNet and Transgrid’s EnergyConnect project is rapidly progressing, with early work activities such as surveying, undergrounding overhead lines and camp construction already being awarded to a range of local, state and interstate businesses, offering various opportunities for local trades. The EnergyConnect electricity transmission infrastructure aims to save NSW customers $180 million a year and generate up to 1,500 new jobs. [...]
Innovative energy efficient equipment can translate into energy savings, a reduction in environmental impact and can help fight climate change. Sustainability is becoming increasingly important across all industries as companies strive to balance economic success with long-term values that take measures to support the effort against climate change and ensure social progress to the benefit of all stakeholders. This quest for sustainability has brought about the need for [...]
by April Shepherd, Journalist, Utility magazine The Transgrid Queensland-NSW Interconnector upgrade, which has involved extensive work on substations and transformers, continues to progress, with the project’s goal of boosting interstate transmission capacity and reactive power in the grid close to becoming a reality. The Queensland-NSW Interconnector (QNI) upgrade aims to ensure a steady power supply for customers by sharing energy [...]
AS/NZS 61439 is a series of standards for low voltage switchgear and control gear assemblies, and helps address the need for portability between Australia and international suppliers. With the release of AS/NZS 3000 amendment 2 – also known as “the wiring rules” – it mandates the use of AS/NZS 61439 series for switchboard assemblies from May 2021. How can you [...]
Whether you are inspecting insulators, transformers, switch gears or high voltage powerlines, you need to be sure that you spot a problem quickly and early. Partial discharge that goes unchecked can cause blackouts, fires, explosions or death from arc flashes. In addition to the danger that partial discharge poses to human lives and the environment, there is a significant monetary [...]
The presence of oxygen in power transformer oil has been shown to accelerate the aging process of the solid insulation. In order to maximise a transformer’s operational life, its oxygen levels should remain as low as possible. Now there is a new method for detecting transformer air leaks that will extend the life of the transformer as well as save [...]
About $37 million worth of electrical infrastructure upgrades are underway in Queensland’s Wide Bay to support the region’s future growth, including the rebuild of Gin Gin Substation and the replacement of insulators on a critical transmission line. Energy Minister, Dr Anthony Lynham, said Powerlink had hit the halfway mark in a $33 million revamp of its 50-year-old Gin Gin Substation, [...]
Powerlink has finished work on a 37km transmission line in Brisbane's southside, ensuring the line will continue to operate safely and reliably for its remaining 40-year service life. The project took about three months to complete and supported nine jobs. Powerlink crews replaced 1,225 insulator strings and steelwork on 105 transmission towers between Belmont and Bundamba Substations. Crews successfully completed [...]
A project which will provide a more reliable power supply to homes and businesses across Sydney’s inner west has reached a major milestone.
