Elimpus installs condition monitoring equipment on National Grid transformers

Supergrid Transformer

Transformer Sensor Instsall


Elimpus has completed the installation of thermal monitoring equipment on several of National Grid’s supergrid transformers in the south of England. The monitoring equipment supports a joint research project between National Grid and the University of Southampton  which is investigating the Condition and Climatic Environment for Power Transformers (ConCEPT) – an NIA funded Innovation Project.

Elimpus provide Partial Discharge detection and location services as well as managing the process of delivering specialist condition monitoring systems to National Grids assets infrastructure.

LCNI 2019 Conference & Exhibition

Elimpus Stand

Very successful #LCNI2019 conference and exhibition at the SEC in Glasgow where Elimpus were able to demonstrate two current NIA funded projects supported by Scottish Power Energy Networks and UKPN. Our innovative use of radiometric technology to accurately detect and locate Arc Faults on distribution networks  (RAFL) will shortly be tested at the PNDC in Cumbernauld whilst our Energy Harvesting prototype has been successfully relaying meteorological information to a cloud server since February this year. No batteries or back up – just energy harvested from 400kV conductors. Elimpus are now looking at a variety of potential applications for this technology including line sag measurement, thermal rating and monitoring of remote cable sealing ends.

#LCNI2019 was also a great opportunity to update existing customers and inform potential new customers of our Partial Discharge products and services  as well as our Condition Monitoring system integration capabilities. 

Continued Success in 2019

From its origins as a technology spin out from Strathclyde University, Elimpus has solidified its position as one of the foremost experts in the field of Partial Discharge in HV equipment. It offers career options both from a practical position with a significant on site presence and in the development area where new products and innovation will maintain the growth of the company as condition monitoring is universally adopted by utlities.

In 2019 we are already looking to add to both our field and development staff to support our plans and currently have an opening for a senior field engineer. Interested in joining Elimpus, please send us your Career Inquiry using the contact for on our Contact page.

Condition Monitoring at world’s most powerful hydro-electric dam

Itaipu Dam

Itaipu Hydroelectric Dam is the largest operational hydroelectric energy producer in the world, with an installed generation capacity of 14GW. The plant is operated by Itaipu Binacional and located on the border between Brazil and Paraguay. Energy generated by Itaipu helps meet demands from the two countries. In 2016, the Itaipu Dam’s hydroelectric power plant set a new world record by producing the most energy of any other plant in the world: 103,098,366 megawatt hour (MWh). In 2015 and 2016, the Itaipu plant surpassed the Three Gorges Dam plant in energy production. A cornerstone of their condition monitoring is the detection and monitoring of Partial Discharge. This summer Elimpus successfully installed its PDtect®4 fixed system and also supplied their PDtect®Explorer. Both solutions use radiometric detection thereby avoiding both invasive and contact interfaces with the high voltage equipment. Installation, commissioning and training was completed in August (2018) by Elimpus Field Services Manager. Elimpus is recognised globally as a leader in the detection of Partial Discharge using radiometric princples.

Elimpus Install Vaisala Online DGA

Elimpus Ltd has installed several of Vaisala’s online transformer

monitoring solutions on behalf of Scottish Power, a leading British

energy provider, to provide real-time condition updates at key sites.

In one particular case the Optimus DGA Monitor OPT100 will give

continuous updates on Scottish Power’s 1000MVA auto transformer

and monitor for the impact of geomagnetically induced currents on

the asset.

DGA Case Study


Service is an important part of the Elimpus offering. It allows us to keep in touch with the real needs at the customer sites and enable customers to benefit from the broad experience of the Elimpus staff.

We are delighted to be recognised by the UK National Grid as a highly experienced and customer focused supplier with the award of a new and expanded service contract to cover the large number of GIS sites.
