HV Efficiency In The Energy Industry

The Core Of The Problem (Part 1 of 3)

  • uploaded by Chris Dodds - Thorne & Derrick Sales and Marketing Manager

Changes in the energy industry happen frequently and can often be complicated to understand. Powerstar simplifies any developments and ensures their clients are kept in the loop with regards to changing technologies. This ensures they have the insight to make knowledgeable decisions about their energy infrastructure including 11kV transformers.

In this 3 part Blog series we will discuss a step by step guide on how your HV infrastructure can by more efficient by discussing the following:

  • Benefits of installing a super low loss amorphous core transformer over a traditional CRGO transformer
  • Difference between stepping down your transformers voltage and purpose-built voltage management technologies, such as voltage optimisation
  • Advantages of installing a smart distribution transformer integrated with remote monitoring capabilities

Since the taking over Bromsgrove Winding Services (BWS) Ltd, Powerstar have been able to extend theiFhatr smart energy solution capabilities which now include distribution transformers.

Now Powerstar are able to offer advice to their clients around the efficiencies of HV infrastructures and how companies can enhance them.

A Guide To HV Efficiency The Core Of The Problem

Greater efficiencies at the core

Many businesses look into upgrading their HV infrastructure to increase efficiencies and decrease electricity consumption, and this has aided advancement of core materials which experience lower losses and are more efficient than the materials traditionally used to manufacture HV transformers.

Amorphous alloy core technology has established a name for itself as providing positive results when studied and tested across numerous applications.

In comparison to CRGO’s the amorphous alloy has a flexible atom structure that allows for easy magnetisation and demagnetisation to occur. In turn this offers enhanced efficiencies and limits the volume of wasted energy.

Another advantage is the distribution transformer can be manufactured to meet the precise needs of the site. When provided, distribution transformers designed and delivered from concept to completion can provide enhanced site resilience and increased HV efficiencies.

The importance of upgrading

your HV transformer

Transformers have a life expectancy of up to 40 years and those currently installed were made from various materials that no longer of high priority.

There has been a significant shift towards using more eco-friendly equipment as the issue of climate change has become more prevalent. Nowadays when upgrading your transformer you need to consider being more environmentally friendly and decreasing its carbon emissions.

Older transformers are often extremely less efficient than newer transformers for example new amorphous core transformers are able to obtain up to 75% lower core losses in comparison to traditional CRGO transformers.

Furthermore new bespoke transformers such as the Powerstar SO-LO amorphous core transformer meets and surpasses 2021 EU Ecodesign Directive standards set by the European Commission.

Older transformers are not likely to adhere to these standards and therefore in spite of their long life expectancy are out of date when measured against contemporary standards.

Changing a traditional transformer with a more efficient amorphous core transformer will reduce energy consumption and costs for businesses who manage their own HV infrastructure.
