Open Access research shaping international environmental governance...

Strathprints makes available scholarly Open Access content exploring environmental law and governance, in particular the work of the Strathclyde Centre for Environmental Law & Governance (SCELG) based within the School of Law.

SCELG aims to improve understanding of the trends, challenges and potential solutions across different interconnected areas of environmental law, including capacity-building for sustainable management of biodiversity, oceans, lands and freshwater, as well as for the fight against climate change. The intersection of international, regional, national and local levels of environmental governance, including the customary laws of indigenous peoples and local communities, and legal developments by private actors, is also a signifcant research specialism.

Abstract

A novel two-tube, two-stage, self-compensating resistive voltage divider with minimized stray capacitance using copper sulphate solution was explored to measure a fast high-impulse voltage output from a cable Blumlein generator. Self-compensation of the probe was achieved by matching the RC time constant in the two dividing stages. Stray capacitance of the probe was minimized by electric field contouring and matching methods. Experiments were carried out to investigate the probe responses as affected by self-capacitance, impedance, and stray capacitance. Calibration of the optimized probe showed a rise time of 15 ns at a load impedance of 8.68 k Omega with a hold-off voltage of 600 kV.
