In electrical wiring and installation,earthing is the important thing that we must make sure it in our job scopes.Earthing system for electrical installation is for the safety and electromagnetic power supply purpose.

Earthing system function is to ensure all equipment or device is safe from risk of electric shock and make sure the residual current device operate properly.

We should decide a suitable types of earthing system for our application and must understand the classification.Earthing system have a several types commonly used in all around the world listed as below :- read more

This is another alternative method for earthing resistance measurement when excellent ground is already available.When we want to perform the measurement for earthing resistance in the compact room or tight area and want to put the two(2) auxiliary rod  may be a problem.

So..to solve this problem,we can use the two point method measurement.This measurement concept is two point into the ground in series technique used to the reading obtained.

The earth surface or other ground must be very low in resistance so that it will be negligible in the final measurement. The lead resistances will also be measured and should be deducted from the final measurement. read more

Grounding or Earthing system is a connection system between metal and ground from the installation of electrical wiring.It is for provide easy access to a low impedance, or resistance to earthing protection system to operate effectively to ensure the safety of people or users from shock hazards electricity in the event of leakage current to earth.

We should prepared the good design for electrical earthing for electrical installation system.It must follow regulation and standard from IEE or Local authority for electrical.In general, the earthing system for electrical installation. read more

When we need to perform Earthing or grounding resistance measurement,the important equipment that we must have is the Earthing resistance tester.

We can found many types and brand of Earthing resistance tester in the market.It’s depend on our budget,requirement and application on actual work site.We need to ensure this device must always calibrated to get the accurate reading.

This equipment is used to measure the resistance ( ohm) of the earth.It is important to ensure that the electrical installation grounding system in accordance with the specifications and meet the earthing requirement. read more
