Future Energy Skills (FES) is always seeking out opportunities to learn more about what is new in the industry and to also provide occasions for staff to improve professionally. In this regard, NHP recently invited FES assessment team members to undertake some further training and development, at their headquarters in Richmond.
The day started with Jeff Davis discussing the AS/NZS 61439 Switchboard standards. Jeff is a great presenter and with his experience as an investigator for ESV, he was able to clearly explain how and why switchboard design has changed over the years. Jeff discussed the need to be aware of, and the requirement for, RECs and/or electricians to calculate the potential short circuit energy at switchboards, particularly in commercial situations. Jeff spoke to the importance of switchboard compliance and type testing certification, highlighting how his role at NHP supports contractors in choosing the correct switchboard and switchgear.
The subject of protective devise selectivity was discussed, as well as circuit breaker types and their different characteristics and tripping curves. Jeff emphasised the importance of selecting the correct device to suit the situation. He also explained the how to, and the importance, of setting moulded case circuit breakers and how this is used in industrial and commercial installations to limit interruption to supply under fault conditions.
Ravi Panneer followed with a presentation on RCD technologies, focusing on RCD principles, the different types, and their applications. Ravi, then went on to discuss energy management solutions and the need for efficiency, especially in the commercial and industrial sectors. Solar energy management systems were discussed, particularly the new requirement to allow space to accommodate future solar charger installations and energy management systems. Ravi’s wealth of knowledge was evident as he spoke about energy efficiency in the form of harmonic filtering, explaining how industry is using the new technology and moving away from capacitor banks for power factor correction. The theory was followed by a demonstration of the equipment and how businesses can be more efficient with the installation of electronic filters.
Finally, Paul Jones presented on the latest in motor control equipment and their practical use. He showed the team some great products and demonstrated their use in the workshop. This included drives and PLC controller cabinets and the new smart motor overload devices that has the ability to send real time data and predict likely overloads.
The team found the day interesting, and valued the chance to take a moment and learn to maintain our industry currency. Future Energy Skills would like to thank NHP, David Decata for organising the day, and the presenters for their hospitality and for taking the time to share their knowledge.
