About Us

About Us

 
High Voltage Partial Discharge Ltd (HVPD), founded in 2006, are experts in on-line partial discharge (OLPD) testing and monitoring. We supply a complete range of on-line PD surveying and diagnostic test technology, PD monitoring technologies and PD test services across the worldwide electricity supply industry.
 
Over 400 customers in over 100 countries already trust our technology.
 

OLPD Testing and Monitoring

We offer diagnostic test and monitoring technology that provides an early warning of incipient faults and deterioration in high‑voltage insulation, allowing plant owners to schedule preventative maintenance interventions.
 
Our unique condition‑based asset management approach comprises a complete range of OLPD test, monitoring and sensor solutions for identification, location and monitoring of PD activity in electricity networks. Our technology is suitable for OLPD testing and monitoring of plant across the voltage range from 3.3 kV to 750 kV.
 
 

Our Knowledge is Your Power

The foundations of our extensive knowledge base have been built on the research and development work carried out by the HVPD directors and senior engineers. This knowledge has been passed on to our training, test and customer service engineers who transfer it to our clients through training courses and data analysis service contracts.
 
We have consistently published the results of our research and development work at a number of international conferences around the world, with over 50 papers published so far.

Dr. Ross Mackinlay

Dr. Ross Mackinlay
 
Dr Ross Mackinlay studied physics at Lancaster University (BA) and Oxford University (D. Phil), his D. Phil Thesis being on the topic of non-linear waves in plasmas. Following this, Ross was employed at the Electricity Council Research Centre, carrying out research and development in the area of electricity distribution equipment. In 1989, he became Head of Cables & Dielectrics at EA Technology after privatisation of the electricity industry in the UK. In 1993 he became Group Manager of cables and power technology at EA Technology. Ross left EA Technology in 1998 and, between 1998 and 2006, he ran his own company, High Voltage Solutions Ltd. Ross is considered one of the world's foremost experts in the field of diagnostic methods for high voltage plant, and has used his significant knowledge and experience of on-line PD testing to help develop a number of HVPD's PD test technologies and software packages.
