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, the damage caused during a ground fault is far less than that caused during a ground fault in a solidly grounded system and the mechanical … Read more
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 are held to a minimum when the system is effectively grounded. In an effectively grounded system, ground fault currents will be considerably higher, making ground … Read more
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 connection to the ground due to the presence of capacitances between the live conductors and the ground. Therefore the so-called ungrounded system is actually a … Read more
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 article let us analyze the causes of neutral to earth/ground voltage, its effect, and how to mitigate it. Note: If you are an electrician troubleshooting your wiring or … Read more
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 to be understood. This article explains the concepts and the difference between earthing and bonding. Note: The terms earth and ground refer to a common … Read more
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 path for the leakage charges to pass to the ground. In addition, the ground is used to detect unwanted connections between the phase and the … Read more
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 in the US alone. Earth leakage relays can be helpful in sensing and mitigating such incidents. What is earth leakage? Earth leakage is an unindented … Read more
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 protect the people getting in contact with them from electrocution. The question, “why one of the pins in a three-pin plug is longer and thicker … Read more
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 safety and protection-related aspects need to be carefully studied for a better understanding of the difference between them. Note: For this article, let us consider … Read more
