Delegates created a real buzz while taking part in the IUS Buzzwire Challenge at the recent Scottish Water Supply Chain Conference at Glasgow’s Crowne Plaza Hotel on the banks of the Clyde.
IUS were pleased to be invited by Scottish Water to showcase our capabilities at the Scottish Water Supply Chain Conference in April 2019. The event focused on the performance and future strategy of the supply chain framework on which IUS have delivered Single Source Power Upgrades for all new and upgraded sites for more than a decade.
The exhibition was an ideal opportunity for IUS to demonstrate its expertise in the Competition in Connections (CiC) market together with our work in private network infrastructure.
An element of fun was incorporated into our exhibition as delegates used steady hands to complete the 8ft long Buzzwire game. Of course safety was to the fore as participants wore an IUS Arc Flash Jacket whilst navigating game.
Debbie Deans (Senior Technical Coordinator) and Steven Robertson (Business Development – Scotland) were on hand to welcome delegates while Gary Milne (Contract Manager) represented IUS as a delegate at the conference.
Absolute operational certainty is vital when it comes to high voltage switchgear. Oil filled switchgear can be prone to failure, faults & requires meticulous maintenance procedures, all resulting in prolonged power outage time which can be detrimental to any business. Operational restrictions, imposed on most fused types of oil filled switchgear, can also be a hindrance in terms of site network power control. IUS’ vast experience working with high voltage oil switchgear has made us aware of the dangers. Some of the main failure modes of dated oil filled switchgear are:
• Faults within oil compartments
• Failure of circuit breaker tripping (which may result in an extended disconnection time due to fault clearance by upstream equipment)
• Solid insulation faults i.e. porcelain bushings and mouldings (external to oil chambers)
• Contaminated insulating oil
• Making or breaking fault current above the rated capability (in case of a circuit-breaker)
• Internal component failure
• Aged mechanism failure
• Compound boxes leaking
• Moisture ingress into oil chambers of outdoor equipment
It may be time to consider upgrading obsolete oil filled switchgear for a modern, newly manufactured alternative.
Through our trusted supply chain IUS can offer replacement alternatives tailored to the requirements of your site. All new switchgear comes with a 12-month warranty guarantee from commissioning date. For further information, or an initial discussion regarding replacement switchgear options please do not hesitate to contact us at firstname.lastname@example.org. One of our Business Development staff would be happy to attend meeting.
