How sigma test is helping meet the Solar power target of India

by Rahul G. Founder

checking the soil's thermal resistivity tests the soil's ability to conduct or discharge heat. For designing and installing underground pipelines and transmission cables, the correct understanding of the thermal properties of soil or layer of rendered ground is necessary to prevent premature failures. The current provided by a subterranean power cable can dissipate the heat properly.

And that is why Sigma is all ready to help provide its clients with Solar Thermal Resistivity Test to meet the Solar Power Target of India.

What does Sigma do –

1. Assists in the planning and construction of underwater pipelines.

2. Prevents the build-up of heat across power transmission cables.

3. Measures the heat dissipation properties of the earth in preparation for pipeline construction.

4. Calculates the best cable requirements for the ground conditions in the region.

5. Determines when in-situ ground must be replaced with thermal back-fill cable bedding.

It is in the area of Thermal Resistivity Monitoring where we excel, assisting clients in saving time and resources by specialized on-site and laboratory research.

Thermal resistance testing may be done on natural soils or specially built quarried materials. It determines the thermal properties of a material and how well it conducts/resists heat.

When testing natural soils, samples are obtained from various sites and dried and analyzed to determine the thermal resistivity versus moisture content relationship. If the native soil surrounding a cable partly dries out under cable working temperatures, this dried-out curve comes in handy.

Based on the type of the substance and the quality specifications, a range of approaches may be used to measure quarry materials for thermal suitability as cable backfill or bedding.

Operation of the Survey

Before the installation of a cable, soil thermal resistivity testing is usually performed. Testing should ideally take place at the installation's proposed cover depth. For many years, the thermal resistivity of porous materials has been measured using transient line heat source methods. Typically, a portable unit is used and consists of a needle with a heater and temperature sensor inside that meets IEEE 442 and ASTM 5334 requirements. A current is transmitted through the heater after the probe is placed into the ground to a given depth.

To generate power, the solar farm's network of electrical cables and conduit generates a tremendous amount of heat.

This heat must be able to dissipate safely in the materials covering the cables, so the material properties surrounding the conduit must be correct.

Sigma’sgeotechnical team takes soil gathered on-site and replicates field conditions in the lab, compacting the soil sample to the same conditions as building soil. This procedure aids in the selection of the proper conduit/cabling device and guarantees that engineers can build the design to the material's optimum degree of compaction.

Furthermore, Sigma uses a variety of compaction ratios to get to a point where they feel the cabling device can fulfill the designer's target specifications.

Sigma thrives on the motto and is known for ‘going the extra mile,' constantly searching for innovation and opportunities to improve research and help clients save money during renovation.

Reusing natural material in the earth during cabling construction is the most cost-effective - and also the most environmentally sustainable - choice. Sigma uses their experience and scientific skills to identify the most suitable materials, assisting clients in maximizing productivity and effectiveness.

Sigma has a broad range of thermal conductivity monitoring services for a variety of sample sizes and temperatures. The cost of conducting thermal conductivity is determined by a variety of factors.

· Material that has undergone testing.

· Tests are on-site and off-site.

· The temperature at which the experiments must be performed.
