APPLICATION NOTES
The Effect Of
Soil Thermal Resistivity (Rho) On Underground Power Cable Installations
Basic information
about the thermal properties of soil for the electrical power
engineer.
Understanding
How Rho Changes With Changing Density, Temperature, Composition,
And Water Content Of Backfill
Get the best
possible thermal resistivity measurements by understanding the
principal factors affecting rho.
KD2 Compliance
To ASTM And IEEE Standards
ASTM updated
the standard in 2008, the IEEE update is in progress. Read about
the current state of the art, the current state of the standards,
and how the KD2 Pro measures up.
How To
Reduce Contact Resistance Errors In Thermal Properties Measurements
Thermal needle
measurements require good contact with the sample. Discover how
to get accurate measurements in dry granular materials, especially
those with large grain size.
Certification
of KD2 Pro Compliance To ASTM D5334-08
The KD2 Pro manufactured
by Decagon Devices is fully compatible with and complies to ASTM
D5334-08 Standard Test Method of Determination of Thermal Conductivity
of Soil and soft Rock by Thermal Needle Probe Procedure.
