Hong Kong Team Perform Maintenance Works in Central-Wan Chai Bypass Tunnel

Ampcontrol’s Hong Kong team were contacted by equipment supplier FILTRONtec to assist with installation and maintenance works on their ultra-modern and efficient Air Purification System (APS) in the Central-Wan Chai Bypass Tunnel on Hong Kong Island.

The FILTRONtec APS is the first high tech system of its kind to be used in a road tunnel in Hong Kong and is the backbone of the ventilation system that provides fresh air to help maintain good air quality for commuters while discharging vitiated air via exhaust points throughout the tunnel.

The scope of these onsite works by Ampcontrol included the installation and maintenance of eight APS systems in the 3.7km long tunnel. The APS can treat up to 1500 m3/s of road tunnel exhaust air and can remove about 80% of the respirable suspended particulates including nitrogen dioxide (NO2), nitric oxide (NO) and nitrogen oxide (NOx).

Ampcontrol has agile service teams based in country across South-East Asia, enabling prompt maintenance support where and when it is needed.

Ampcontrol Power New Mine Expansion In India

Powering equipment in some of the most hazardous environments across the globe comes as second nature here at Ampcontrol. Recently, several of Ampcontrol’s AUK products made their way from our UK manufacturing facility in Prestwick, Scotland to the PVK-5 Coal Mine in Telangana, India.

Designed to help power equipment as part of a mine expansion, a 10 drive AUK5000 Power Centre and 4 drive AUK1000 550V Motor Starter was delivered and commissioned with long standing customer Gainwell Commosales Private Limited (GCPL) by Ampcontrol’s Indian Service Engineering Team.

The AUK5000 had an incoming supply of 3,300V feeding the primary windings of the 1.5MVA Transformer via a 3,300V E10 HV Circuit Breaker. The dual voltage secondary windings provided 1,100V and 550V to the 10 drive Load Centre. All the equipment was coupled together and mounted on a custom-built skid to allow the Powercentre to be transported safely underground.

All equipment was fully examined and tested before the 3,300V site supply being applied to the equipment, with all functional tests carried out to GCPL requirements and specifications.

Practical training on the AUK5000 Power Centre and AUK1000 Motor Starter was also provided by the Ampcontrol Service Team to ensure the GCPL Engineers were familiar with their new equipment.

Additional training on the AUK product range functionality enabled the customer to gain insights into how to adjust the equipment for use in a different application.

Join us in June for our ‘Safety In Mining’ Webinar Series

As an industry leader offering integrated electrical protection, integrated power distribution systems, monitoring and control solutions and communication systems for coal and hard rock mining, we’ve launched the Ampcontrol Group ‘Safety in Mining’ webinar series. Running throughout June, we are offering a range of free, technical presentations designed for industry.

Kicking off on June 9, we’ll be welcoming ResTech Principal Engineer, Dr Peter Stepien, who will share insights from his ACARP research project around the ‘Control of Touch Potential Transients During Switching’. During a number of investigations into electric shock incidences in the past, machine frames measured touch potential transients when switchgear closed or opened. There were no faults present in the equipment or the earth fault limited supply, yet touch potentials occurred. This webinar will step participants through Peter’s current research that aims to understand the method by which these touch potentials occur and determine a method to eliminate them to improve mine safety.

On June 16, Philip Reilly, Ampcontrol’s Oil Service Manager, will deliver his webinar titled ‘Oil Analysis: Testing OLTC & Managing Corrosive Sulphur in Transformers’. Managing a large fleet of ageing transformers is a technical challenge faced by many Australian mines and reliability surveys show that the On Load Tap Changer (OLTC) can account for up to 30% of all transformer failures. This webinar will address failure modes & available condition monitoring techniques and will also outline the role of oil analysis.  The webinar will also provide insights into the mechanism of copper sulphide formation in transformers, failure modes, details of service experiences, and what assessment and mitigation techniques are available. 

Finally, Ampcontrol Group Engineering Manager, Dr Ian Webster, will deliver his webinar titled ‘Arc Faults (and Flashes) and the Hierarchy of Controls’ on June 23. This webinar will look at the application of the hierarchy of controls to the hazards associated with arcing faults in high powered electrical equipment in general, and in confined spaces such as mines and tunnels. 

We’re committed to connecting industry contacts across Australia with practical insights into real world issues being faced onsite. Attendance is free, secure your space today at one or all of the webinars in the series.

Ampcontrol Calls on Strong University Connections

University of Newcastle expertise sees lifesaving ventilator prototype secure state backing.

Each year The University Of Newcastle (UON) produces thousands of talented graduates and they watch with pride as they trade the campuses for new workplaces, set to make their mark on the world and in their local communities. Amid the COVID-19 pandemic, a group of almost thirty Hunter-based UON alumni and staff have done just that – contributing to an emergency ventilator prototype project led by Ampcontrol to be selected by the NSW Government for pre-production.

Project Lead and Faculty of Engineering and Built Environment Conjoint Senior Fellow and Ampcontrol Group Manager Engineering, Dr Ian Webster, said the success of the project relied on the strong connections between Ampcontrol and The University of Newcastle.

“When we kicked off this project, we were asked to produce 600 ventilators in 28 days. My affiliation with the Faculty of Engineering meant I could immediately reach out to Brett Ninness, as I knew the expertise and facilities housed at UON would be hugely beneficial to the project,” Dr Webster said.

“Since 2004, we’ve had a unique partnership with the University via our joint venture ResTech, which has created a direct path for students to complete placements and do research work with Ampcontrol.

As a result of the strong engineering alumni network in the Hunter Region, around 60% of the ventilator prototype team are UON alumni. Safearth, and NewieVentures – both Hunter-based leading engineering companies with strong alumni ties – also came on board as collaborative partners. The University of Newcastle graduates have a unique set of skills that make them ideal candidates for the work we do. I’m so proud of the team who are working tirelessly to ensure our clinicians have the lifesaving equipment they need.”

The ventilator prototype, dubbed ‘Anemoi’, will now move into production of 10 units for further testing. If the model is successful in completing the pre-production phase, full production would be manufactured in NSW supporting the local industry, the local economy, and employment.

“This prototype is likely to become a new manufacturing product, diversifying our business and supporting regional development,” Dr Webster said.

To quickly accelerate their knowledge of ventilator systems, the Ampcontrol team engaged with the University to guide solutions and minimise clinical and deployment risks.

Professor Brett Ninness said our COVID-19 response was a powerful example of collaborating across STEM disciplines.

“COVID-19 presented a situation where people skilled across health, science, engineering, design, and commercialisation needed to come together to rapidly collaborate to solve imperative global issues. We were part of that solution, so this is a proud moment for us all to celebrate,” Professor Brett Ninness said.

“Our strong industry connections have proven invaluable in ensuring our people are embedded in the local response to COVID-19 and our graduates remain highly sought after for their expertise.”

“This is another example of the power of the University of Newcastle, local business, and government partners coming together to demonstrate leadership on important issues in our region and beyond.”

The NSW Premier said that with the easing of restrictions there could be a rise in COVID-19 infections, in which case it’s imperative hospitals to have all the equipment they need. Read NSW Premier Gladys Berejiklian’s announcement here.

Remote Transformer Health Check Enables Fast Repair at Sugar Mill

Our transformer maintenance services team were contacted by an Asset Manager at a large Queensland sugarcane refinery after they reviewed their most recent transformer insulating oil analysis report. Results indicated occurrence of a serious T3 Thermal Fault – high temperature heating (> 700°C). Typically, these faults include large circulating currents in the tank and core, loose connections in the HV winding circuit, and misalignment of contacts in de-energised tap changers.

The request was to further review the test data provided by the Asset Manager, to offer an independent engineering opinion and to help pinpoint the cause of the problem. Recommendations for further investigation and management of the asset were also sought.

Resulting recommendations included regular DGA testing to monitor the fault and electrical testing to investigate the cause of the DGA gassing problem. Further recommendations also included an internal inspection / videoscope to identify burnt / misaligned contacts in the DETC (off load tap changer). Acetylene generation in the transformer pointed to either the severity of the fault or the involvement of electrical contacts.

On receipt of Ampcontrol’s recommendations, the Asset Manager conducted an internal investigation on the transformer. The source of the fault was identified as a contact in the DETC.
