 Why There is Electricity in the Ground Wire

The ground wire or grounding socket is one of the most important electrical wires found in household electrical installations and because it protects electrical devices from leaking electrical current, as it directs it to the ground with less resistance in the event of a leak. 


This protects electrical devices and people alike, and it must always be installed a differential breaker to disconnect the electrical current in the event of a leak. In the article, we will learn about the reasons for the presence of electricity in the ground wire . Is it normal or not?


 Reasons for the presence of electricity in the ground wire:

 The ground electrical line usually does not contain electricity unless there is a defect or problem in the electricity network system, which could be due to several reasons:

Why there is electricity in the ground wire

 The first reason: electrical current leakage

 In fact, the landline does not contain electricity unless the current leaks through one of the broken electrical devices or has a poor electrical connection. Therefore, electrical current leakage is considered one of the most important reasons for the presence of electricity in the landline.


 The second reason: exposure to lightning

 Lightning strikes cause a sudden increase in electrical current, so the excess electrical current in the ground line must be discharged to the ground.


 The third reason: electromagnetic effects

 Some equipment, such as high-power transmission wires, may cause some magnetic influences and interference, causing electricity to be present in the ground wire. 


 Fourth reason: problems with electricity distribution transformers

 Electricity distribution transformers are one of the reasons for the presence of electricity in the ground wire because it may leak to the ground.


 The grounded electrical line plays an important role in protecting electrical devices, even though it does not pass electrical current except in the event of a current leakage or a defect in the electrical installations. 

Therefore, it is recommended to use RCD ground leakage protection devices with high efficiency and performance, and it is advised not to use the devices,  Malfunctioning electrical appliances are the main cause of current leakage and the presence of electrical current in the ground line.
