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.
