Resistance grounded system
A resistance grounded system or resistance grounded neutral system is one that employs an intentional connection between the neutral and the earth through one or more resistors. In these systems,…
Solidly grounded or Effectively grounded system
In a Solidly grounded system, the neutral is directly connected to the earth without any intentional resistance or reactance in between. Compared to the other grounding systems, the transient overvoltages…
Ungrounded systems
An electrical system that is not intentionally connected to the ground is known as an ungrounded system. Even though the system is not connected to the ground, there exists a…
Neutral-to-Earth/ground Voltage- Causes, effects, and solution
Image source: electronics.stackexchange.com Ideally, the voltage measured across the neutral and the earth/ground must be zero. But sometimes there exists some measure of potential difference between them. Here, in this…
Difference between grounding/earthing and bonding
Earthing and bonding are two terms very closely related but are different. Even though earthing and bonding are meant to prevent electric shock, they have a subtle difference that needs…
Types of grounding
This article discusses several types of grounding methods. The intention of providing the proper ground is to control the voltage with respect to the ground and provide a low resistance…
Earth Leakage Relay (ELR)
An earth leakage can represent a danger to life or property if it is not located and mitigated. Studies have revealed that at least 500 people experience electrocution every year…
Why is the earth pin in a three-pin plug longer and thicker than the other pins?
Safety is the primary element of any circuit or electrical connection. Whether it is electric iron or refrigerator or any other home appliances, everywhere safety has to be ensured to…
Difference between neutral and earth / ground
This article focus on explaining the similarities and dissimilarities between neutral and earth (ground). Understanding the difference between neutral and earth may be difficult in the beginning. A Lot of…
