Transformers

Utilligence makes, designs, builds, supplies and installs a wide range of transformers. Whether it’s step up, step down or low or high voltage, we have a comprehensive range of transformers to meet the needs of our customers.

  • Power transformers
  • Distribution transformers
  • Cast resin transformers
  • Low loss transformers

Power transformers are essential components that enable DNOs to efficiently distribute electricity at different voltage levels, ensuring a reliable supply. 

While off-the-shelf solutions might be adequate for some scenarios, they often fall short of meeting the specific requirements of DNOs, who have unique and demanding operational needs, including high power capacities, complex grid configurations, stringent safety standards and diverse load demands and environmental factors. Bespoke power transformers which are tailored to the precise needs of each DNO are imperative for ensuring optimal performance and operational efficiency.

Utilligence are expert in the design and manufacturing of power transformers for DNOs. We understand load fluctuations, cooling systems, insulation materials, and protection mechanisms. Investing in bespoke power transformers enables DNOs to mitigate potential risks, enhance reliability, and maximise the lifespan of the transformers, optimising the overall performance of their power grid.

Whether you need a maintenance solution, a simple replacement for a single distribution transformer or a complete overhaul of your power solution, we can help. Our customers benefit from world-class solutions, competitive pricing and the attention to detail of our consultancy-style approach.

Our design team has expert low and high-voltage engineers to ensure that we can design transformers and control systems of any size, voltage or type.

For customers who are making the move towards net zero, we also offer transformers that harness biodegradable, non-corrosive oils, as well as solid-state versions. As part of our bespoke service, we can design to your unique safety requirements, or a transformer that operates under specific fault conditions. You tell us what you need, and we’ll design it!

Utilligence also offers a transformer testing and diagnostic service, to identify transformer issues and optimise performance.

Kemada Ltd

 

Utilligence’s solution to our projects was to provide a combined substation which comprised a DNO substation and customer substation in one bespoke 40 ft container, customised to comply with all regulations in a reduced space. High-quality switchgear was installed, wired and tested before delivery to the site, which helped us to make our site productive before expectations, alongside all their assistance with DNO communications.

 

GMI Ltd

 

GMI and Utilligence have been working on several generation sites together where Utilligence have been providing HV studies. Alongside this, Utilligence has been able to supply transformers to cover all our requirements, particularly related to impedance. From 11kV to 132kV POC, they are able to build the bespoke transformer needed and deliver it to any location in the UK.

 

VP Flexgen

 

Utilligence provided us with high quality, ENO approved switchgear as part of a project to deliver a STOR site in a challenging location in Weston Super Mare. Their expertise ensured that they rapidly understood our requirements and delivered safe, quality switchgear that has helped us ensure the quality of service that our site demands.

 

Utilligence transformer services: 

E
The amount of renewable generation that is being installed on electrical networks is rising each year. The power electronics integrated into solar PV, wind turbines and battery energy storage schemes are increasing in power output. To reduce losses, the voltages from inverters are approaching 1000V on the LV side of the transformer. Sizes of transformers are also increasing – from what used to be a standard 1MVA, to 6 or 7MVA. Transformers are also often provided with two windings on the LV side, to reduce the current to a more manageable level and to reduce fault levels.
E
Utilligence is a transformer manufacturer with our own in-house design department, who oversees both the design of the transformer and the design of the network that the transformer is integrated into. We can advise on transformer parameters and the appropriate protection schemes, from simple overcurrent and earth fault protection, to multi-ended transformer differential protection and negative phase sequence protection of the LV side of the transformer. Restricted earth fault protection can also be applied to the JV and LV windings.

E
Specifying or designing and building the transformer and protection is only part of our work. Our specialist transformer team will oversee the construction and factory testing of the transformer in our ISO9001 factory, before our teams delivers and installs the transformer on site. We also carry out all testing, including cables and protection schemes, before signoff and handover.  
E
We also offer transformer inspection and replacement services and also offer switchgear and full containerised substations.

Low loss distribution transformers

We provide transformers that meet tiers one and two of the EU Eco Design Directive and are fully compliant with industry standards, including BS, IEC and ANSI. 

 For a transformer with reduced fire risk and optimised environmental performance, our efficient distribution transformers are an ideal option, to support adherence to the stringent environmental standards of your site. We have distributed transformers available that use fully biodegradable transformer fluid, with the added benefit of enabling a safe increase on transformer loading, or a transformer size reduction. 

 Our focus is on maintaining maximum efficiency, minimising power loss and saving you money over the lifetime of your transformers. This commitment to environmental performance can also be used to support your adherence to environmental standards such as ISO 14001. 

 A wide range of switchgear can complement all of our power transformers – either closed coupled or free standing as required. 

 All of Utilligence’s transformer designs can be configured to meet your specific requirements - get in touch to find out how we can help.  

Distribution transformers

Utilligence provides both standard and custom-designed distribution transformers. Our manufacturing team can craft these transformers in radiator style, corrugated tank, or cast resin, ensuring a range of options to suit your needs.

A distribution transformer plays a crucial role in stepping down voltage levels for efficient electricity distribution. Drawing on our extensive experience, we have successfully delivered tailored solutions for a wide variety of applications. Whether it's for industrial, commercial, residential, or renewable energy use, our distribution transformers can be adapted precisely to meet your specific requirements. 

We offer a range of insulation options, including liquid-filled and dry, with reduced fire risk and improved environmental features.

Power transformers

Whatever your power needs, we can provide the solution, with the capacity to supply transformers, from 5MVA to 1000MVA and 415V to 750kV. 

Our power transformers are made for your specific needs. Committed to quality, we source our components from the world’s best suppliers and manufacture to our own high standards.

We work closely with you throughout the entire process, from manufacturing to delivery and installation. 

Our highly experienced engineers will support you from your initial enquiry until the successful completion of your project. You can rely on outstanding technical support coordinated by a dedicated account manager.
