V-LIM Insulation Monitoring Device
Continuous insulation monitoring under live conditions
High accuracy measurement up to 10 GΩ
Stable performance in electrically noisy environments using V-NET Sync
Proven in subsea and harsh industrial applications
Retrofit or integrate into new systems with minimal disruption
Overview
Electrical insulation degrades over time due to harsh environments, moisture ingress, and ageing infrastructure, creating hidden risk that can lead to failure, safety concerns, and costly downtime. V-LIM provides continuous insulation monitoring with real-time visibility of cable health, enabling early intervention before faults occur.
Improve reliability and reduce downtime
V-LIM enables early identification of insulation degradation, helping to reduce unplanned downtime while improving electrical safety and overall system reliability. By providing continuous, accurate data, it supports more effective, data-driven maintenance strategies and contributes to extending the operational life of critical assets. Whether embedded, retrofitted, or used as a portable diagnostic unit, it supports proactive maintenance and early fault detection, extending system life while improving safety and operational stability under both energised and de-energised conditions.
Accurate, continuous insulation monitoring

Case Study
V-LIM hardware enables V-LIFE protection
We retrofitted V-LIM units to an ageing subsea control system for a global operator to improve reliability and reduce unplanned outages. Continuous monitoring delivered early warning of insulation degradation, enabling proactive maintenance before failure occurred.
By combining V-LIM with remote V-LIFE activation, we avoided a costly subsea intervention and extended the asset’s service life, demonstrating clear value in demanding, high-integrity subsea environments.
