Energy Excellence Continues at Trelleborg AVS Leicester

Utilisation de transformateurs SO-LO intelligents pour réduire les pertes d'énergie

At Trelleborg Solutions antivibratoires in Leicester, we thought we had covered and installed most energy reducing technologies, from new energy efficient motors, through to building management systems with LED lights throughout and a SCADA system that controls all the main equipment on the shop floor so only what we need to run is switched on.  Coupled with our Energy Monitoring capability we thought we were doing well.

Le défi

Alors que nous continuons à chercher d'autres moyens de réduire notre consommation d'énergie ou nos coûts énergétiques, nous avons exploré des technologies telles qu'une batterie pour l'écrêtement des pointes de consommation d'énergie, la production de notre propre électricité à partir de gaz et l'énergie solaire.

Whilst investigating the battery option we were made aware of the latest super low-loss amorphous core Transformateurs by Powerstar.  We always saw a difference between our electricity bill (our input) and our internal monitoring readings, however, we put that down to maybe the accuracy of our monitoring and/or maybe time differences.  It turns out it most of it was the transformer causing the loss.

Depending on the age of the transformer, typically depends on the amount of loss it is likely to be experiencing within the high voltage infrastructure resulting in wasted electricity and higher than necessary electricity costs.  Our existing transformer was approximately 18 years old, not that old for a transformer, however, even then it was losing enough compared to today’s technology to make it worthwhile changing it.  This allowed us to continue our sustainable focus, gain further energy efficiencies and reduce our electrical consumption.

La solution

Suite à l'analyse, Powerstar nous a aidés à identifier que le transformateur existant subissait des pertes élevées et que nous pourrions bénéficier de son remplacement par un transformateur à noyau amorphe à très faibles pertes, le Powerstar SO-LO.

The amorphous core enables magnetization and demagnetization to take place at a much quicker rate than in traditional cold-rolled grain-oriented (CRGO) silicon steel Transformateurs which enables it to deliver greater efficiencies than aging, traditional Transformateurs.

En outre, le nouveau transformateur SO-LO est doté de capacités de télésurveillance en ligne qui nous permettent de contrôler à distance les principales caractéristiques de performance du transformateur à tout moment, depuis n'importe quel endroit disposant d'une connexion Internet sécurisée.

Savings & Benefits

En remplaçant le transformateur existant sur le site, nous sommes en mesure de réaliser une économie d'environ 2 % de sa consommation annuelle de kWh, ce qui se traduit par un retour sur investissement de moins de 3 ans !

The post-decommissioning analysis revealed that by upgrading to the Powerstar SO-LO distribution transformer, it is providing the Leicester site with 44% fewer losses on its transformer, equating to a saving of roughly 135,000 kWh per year.  This was approximately what we calculated beforehand, so we are very pleased.

Paul Race, BU Digital Transformation Manager said, “It’s amazing the amount of savings from this improvement, everyone – including us – are more internally focused. By just expanding our horizon to include the transformer infrastructure we were able to unlock a 2% saving across the site in one project.  We use quite a bit of electricity, so when looking at this for other sites, the amount of electricity being consumed and the cost per unit play a part in the payback, that said so does the age of the transformer and our previous one was relatively young !”
