New research will underpin testing of ultra-high voltage equipment used across a range of industries

This project supports the standardisation of ultra-high voltage measurement techniques, focussing on the needs of three different industrial sectors. One part of the project focuses on high-voltage measurements for medical X-ray equipment. The traceable measurements of practical peak voltage and exposure time provided by the project ensure a better control of the dose delivered by X-ray units used in fields such as radiology, mammography and dentistry. This will help to ensure good diagnostic performance while keeping radiation doses to patients to a minimum. Another aspect of the project focussed on measurements of partial discharge in high-voltage power systems. The capabilities developed improve the reliability of the power supply from high-voltage direct-current transmission lines, which are increasingly being deployed across Europe due to the low-loss, long-distance energy transmission offered. Finally, the project provides new calibration methods for fast transient sensors, to address the needs of the electrical power industry.
