A resonant grounded system can significantly reduce the ground fault currents. This grounding system basically consists of a tuned reactor connected between the neutral and the ground that resonates with…
In a reactance grounded system, the neutral is connected to the ground through an inductance (inductive reactance). The magnitude of the ground fault current can be limited to a value…
IEC 60529 has classified the degree of protection offered by an enclosure against solid particles and liquid. This classification is known as the ingress protection code/ IP code/ IP rating/…
Effective electrical earthing plays an important role in safeguarding people from the risk of electric shock and ensures a low impedance path for electric discharges to pass to the general…
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,…
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…
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…
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…
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…
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…
