Earth (earth's soil) is a natural resource that is
abundantly available for plantation or for building foundations. Earth has the
property of conductivity i.e. soil has the resistance to the passage of
electric current. It is earth's abundance and availability that makes it an
important component of a properly functioning electrical system. The device
that is used for measuring the earth resistance is earth tester. The earth ground tester that can be used for accurate readings is digital tester over the
analog tester, as digital tester has digital timers, voltage regulators and
digital display.
Earth's resistance depends on humidity of the soil, amount of moisture content and the temperature, which determines the accuracy of measurement. Resistance of earth is measured by resistance meter basically for:
· Sizing and projecting grounding grids.
· Shaping the usefulness of ground grids and also the links with electrical systems with an aim to protect both the people and equipments
· Obtaining the measured resistance values to get the idea of what is below the earth's surface.
There are some situations that are extremely dangerous like Earth leakage and Stray voltages of electrical components. They can affect not only environment but the people at workplace. To check such there is an effective device called Earth clamp meter. Through this device one can ensure that:
- Electrical appliances are running efficiently
- There is
no power loss.
The reason why the tool is very popular among the industrial users is that they are:
- Effective
- Time saving
- Quick and
easy to measure
Electrical measuring instruments are very helpful to measure electrical elements like power, voltage and current. So, it is very essential that they should be manufactured with utmost precision and accuracy. The sellers should check them properly before supplying them to industrial as well as residential users.
