V-LIFE Ready.

Additionally, V-LIM is V-LIFE ready – an exclusive feature for subsea applications which can be activated to increase the system IR and availability without the need for costly intervention or risk of introducing new faults.

The principle of insulation monitoring is to apply a voltage between the copper conductors in a cable and earth and measure the resulting current that flows. Using any Insulation Monitoring Device (IMD) to monitor IR degradation in a cable which is submerged in seawater will cause damage to the copper conductors at the point where the conductor insulation is damaged. The V-LIM has been designed to substantially reduce the copper loss when compared with competing devices on the market. By enabling V-LIFE the copper loss can be almost entirely eliminated.

V-LIM forms part of Viper Innovation’s V-IR product line offering a granular view of the subsea electrical network, it’s component and cable condition, as well as fault identification and location.
