Demonstration of an Online Continuous Monitoring System for Partial Discharge on Critical HV Cables

INEOS is a major multi-national group of companies specialising in petro-chemical production.

Its largest manufacturing site is based at Grangemouth, Scotland, which is home to its Olefins and Polymers (O&P UK) business, as well as a crude oil refinery that produces the bulk of Scotland’s fuel.

This paper describes a joint Pilot Study between the two companies to install an online Cable PD monitoring system on 18 critical 33kV XLPE cables that link the INEOS owned Combined Heat and Power (CHP) plant to the main distribution substation at INEOS’ O&P UK manufacturing site at Grangemouth.

The paper demonstrates how INEOS’ pro-active approach to managing PD on its critical HV cables has helped to save money, whilst at the same time, enhance the reliability of its electricity distribution network at its site at Grangemouth.
