Distribution infrastructure technology has moved on in recent years and become more efficient. Transformers have to be built to an Ecodesign Standard. Other elements, such as Power Factor Correction, have improved in capability. As long term panel builders, we understand that even the switchgear element is more efficient due to lower losses designed into circuits.
Points to consider
The most likely scenario for your infrastructure is that you’ll have a transformer, with associated switchgear. There may some filters, drives and power factor correction. You may have your own MV ring or share a transformer with other local sites. It is possible that, if you have multiple transformers, they aren’t loaded efficiently and this will be costing you money.
Unless your site has its own generation, your power is delivered to a standard design, and may not be suitable for your current needs. It may be that it was done many years ago and things have changed, or you need a means of getting more power into your plant. Plug-and-play rarely applies when it comes to building supply infrastructure. It requires expert support to ensure that not only regulations are met, but that you’re also gaining maximum efficiency from this vital piece of your operational jigsaw.
A growing issue is the prevalence of Harmonics, which can cause tripping and damage to equipment around the site. Many types of equipment (variable speed drives, electronic ballasts, etc.) and computers generate harmonics. The effects can sometimes be significant. Heat and vibration potentially reduces the efficiency and service life of equipment such as capacitor banks used for power factor correction.
