Are earthing and grounding the same?
Ground and/or Earth are generally used to define a common reference point for power/signal. While IEC (IEV ref 195-01-01) defines this reference point as earth, IEEE (Standard Std 142-2007) defines…
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…
