Neutral-Grounding-Resistor System

Neutral-Grounding-Resistor System Neutral-Grounding Resistors (NGRs) are used to ground power systems by inserting a resistor between the system neutral and ground. This lowers the prospective ground-fault current to a predetermined value. A properly designed resistance-grounded system provides benefits over both ungrounded and solidly grounded systems. Because the system is grounded, transient over voltages do not…

Difference between Bonding and Grounding

Bonding vs Grounding Bonding is the lasting joining of metallic pieces to form a conducting path which ensures safe electrical continuity. Bonding is generally done as protection from electrical shocks. Any intentional or accidental connection between an electrical circuit or instrument and the earth is known as Grounding. Grounding ensures that all metal parts of…

What is Electrical Earthing and Types of Earthing

What is Earthing: The main reason for doing earthing in electrical network is for the safety. When all metallic parts in electrical equipment’s are grounded then if the insulation inside the equipment’s fails there are no dangerous voltages present in the equipment case. If the live wire touches the grounded case then the circuit is…

Difference between Neutral, Earthing and Grounding

The Main difference between Neutral, Ground and Earth? ‪To understand the difference between Neutral, Ground and Earth, we must understand the need of these things first. Neutral Neutral is return path for an AC circuit which is supposed to carry current in normal condition. This current may be because of many reasons, primarily because of…

How to measure Earthing resistance in your Home

How to measure Earthing resistance in your Home   Ground system design Simple earthing systems consist of a single ground electrode driven into the ground. The use of a single ground electrode is the most common form of grounding. Complex grounding systems consist of multiple ground rods, connected, mesh or grid networks, ground plates, and…
