Our range of oil tests and analyses help you spot faults, contamination, degradation and aging in electrical assets early. Once analysed, our expert reporting can be accessed via our online portal, OLIMS, providing a holistic view of your asset health across the fleet.
Regular oil sampling optimises maintenance intervals, improves reliability and minimises both disruption and costs across your asset base.
Comprehensive oil diagnostic services that support every stage of your asset health assessment.
Assess the operational performance by detecting gases produced by overheating, arcing and partial discharge to identify developing faults in transformers.
Drive maintenance practices by measuring moisture, acidity, breakdown voltage, dissipation factor, IFT and other indicators of oil condition and performance.
Assess the ageing and condition of transformer paper insulation, helping estimate remaining asset life and inform replacement strategies.
Measure solid particles, fibres, sediment and sludge to identify contamination that can affect insulation and transformer performance.
Identify PCB contamination and assess corrosive sulphur, DBDS, passivator and inhibitor content to support compliance and maintenance.
Assess the tendency of insulating oil to generate gases under normal operating conditions, helping distinguish oil-related gassing from developing transformer faults.
Analyse insulating oils from tap changers, switchgear, cables and other electrical assets to assess condition, contamination and performance.
Convert oil analysis results into a simple holistic asset health and risk rating for your fleet.

Oil analysis is only as reliable as the sample provided, which is why we offer collection and sampling services to customers without the in-team capabilities and bandwidth. Our trained engineers use controlled procedures designed to prevent contamination and gas loss during collection, alongside the kit and collection for optimal data integrity.
Real-world insight from oil and electrical asset experts with decades of technical experience.
Technical insight, research and commentary from across our engineering and consultancy teams.
