  • Earth Resistance Measurement
    The main factors that should be considered in order to get an accurate earth resistance measurement in electrical systems are analyzed. The measurement system geometry, including minimum distances that should be taken into account, is particularly considered.
  • Getting Down To Earth. A Practicle Guide To Earth Resistance Testing
    Nothing is quite so common or abundantly available throughout the world. as the earth's soil. We are more apt to think of earth as something to be. tilled for planting or to be excavated for a building foundation. Yet, it also. has an electrical property -- conductivity (or low resistance
  • Resistance: SAN-EARTH M5C vs. Copper Wire
    Resistance: SAN-EARTH M5C vs. Copper Wire
  • Earth Ground Measurements
    resistance (impedance) to any other ground system on earth. A good ground system measurement would be between 5 and 10 Ohms. A well designed 5 Ohm ground system is usually considered optimal for a lightning ground system.
  • Windfarms - Grounding with SAN-EARTH
    Wind turbines are located in open spaces often in rocky mountainous areas where soil resistivity is high making them particularly vulnerable to lightning currents that may threaten human life or damage expensive equipment. Partnered with surge protection devices (SPDs), a low resistance path
  • SAN-EARTH M5C vs. Bentonite
    Customers looking for ways to achieve low resistance grounds sometimes think that SAN-EARTH M5C conductive cement and Bentonite will provide similar results. Nothing could be further from the truth.
  • Practical Measures for Lowering Resistance to Grounding
    Using SAN-EARTH to Reduce Grounding Resistance<
  • The Benefits of Designing & Testing a Low Resistance Grounding System
    . Standards for equipment performance mandate the installation and maintenance of a reliable, low-resistance earth ground. These standards often cannot be met and certainly cannot be assured for the long term by traditional grounding methods, which call for minimum requirements. Much of this equipment
  • San-Earth (R) Technical Review
    PRACTICAL MEASURES FOR LOWERING RESISTANCE TO GROUNDING
  • Lightning Transients
    The major mechanisms by which lightning produces surge voltages are the following: * A direct lightning strike to an external circuit (outdoor) injecting high currents producing voltages by either flowing through earth resistance or flowing through the impedance of the existing circuit
  • 5 Tests to Calibrate Your DT80 Range Data Logger
    temperature-controlled environment (i.e. ±2°C) during the course of testing. This prevents temperature drift effects of the reference voltage and reference resistances. The limits shown in the sample report assume that the test environment is between 5°C and 40°C. For the same reason, the datalogger
  • Alltec Protection Pyramid
    implementation begins with the installation of a stable, low resistance and low impedance grounding system to bond all electrically conductive surfaces together. TerraDyne (R), TerraFill (R), TerraBar (R), and TerraWeld (R) grounding product lines are utilized to safely direct lightning energy to the earth
