soil thermal resistivity Services
Why do we need soil thermal resistivity service?
Soil thermal resistivity testing measures the capacity of the ground to conduct or dissipate heat. A correct understanding of the thermal properties of a soil or layer of made ground is important for the design and installation of underground pipelines and transmission cables, to avoid premature failures.
The heat produced by current flowing through an underground power cable must properly dissipate heat.
Typical Applications of soil thermal resistivity
- Firstly assists the design and layout of underground pipelines
- Secondly prevents occurrence of heat build-up around power transmission cables
- Measures the ground’s heat dissipation properties for a pipeline installation
- Calculates the optimum cable specifications for the local ground conditions
- in addition, determines if in-situ ground must be replaced by cable bedding thermal back-fill
Survey operation
Certainly, determining this test in the laboratory or field measurements by MSTR-1 equipment
A typical probe for measuring is a handheld device comprising a needle with heater and temperature sensor inside, which conforms to specifications outlined in IEEE 442 and ASTM 5334. The probe is inserted into the ground to a specified depth and a current passed through the heater. The system then monitors the temperature of the sensor over a period of time. Analysis of the sensor temperature determines the soil thermal resistivity of the material surrounding the probe. Most importantly, heating times as short as possible, to minimize thermally induced water movement and reduce reading times. As a result, Temperatures can measure to high accuracy.
Processing and analyzing results at the office
The results obtained from the MSTR-1 automatic meter record temperature parameters over time. After that, by analyzing data, applying international calculation standards, professional ability, practical experience, we calculate the soil resistivity temperature effectively and accurately.
