Bender ISOMETER® iso685 is a market leading insulation monitoring device used by customers worldwide in unearthed IT system AC, AC/DC and DC power supply applications.

This new isoHR685W was designed specifically for subsea cable monitoring to deliver even earlier warning of developing electrical faults in subsea oil and gas applications. 

Below the surface, cables are a significant asset in the extraction of oil and gas from the seabed.  Operators are demanding even earlier warning of insulation cable failure to maximise warning and planning time, as the time and cost penalties to install, replace and repair subsea cables is considerable.

With cable failure impacting both resource and production output, the earlier the warning of developing failure the fewer the losses longer term.

isoHR685W-D

The variant of the iso685, the isoHR685W-D monitors subsea and umbilical cables to provide very advanced warning of cable degradation and failure.  It is designed specifically to meet the needs of the oil and gas industry sector.  The isoHR685W-D examines the cables up to 10Ω, meaning the team working on the oil rig that’s cable has developed a fault will be notified in time to replace and continue with extracting from that subsea well.
