protective ground. An electrical connection or connections to an approved ground for establishing and maintaining a common potential on conductors connected to it.Click to see full answer. Moreover, what is grounding and what protection does it offer?Grounding’ a tool or electrical system means intentionally creating a low-resistance path to the earth. When properly done, current from a short or from lightning follows this path, thus preventing the buildup of voltages that would otherwise result in electrical shock, injury and even death.Also Know, what is an IT earthing arrangement? IT earthing system In an IT earthing arrangement, there is either no earthing at the supply, or it is done via a high impedance connection. This type of earthing is not used for distribution networks but is frequently used in substations and for independent generator-supplied systems. Just so, what is the purpose of grounding? Grounding is required to provide least resistance path to high voltage surges (fault current) incurred in electrical system due to short circuit/lightning. To protect the electrical equipment from getting damaged under the fault condition.What happens if ground wire is not connected?The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. In the absence of the ground wire, shock hazard conditions will often not cause the breaker to trip unless the circuit has a ground fault interrupter in it.
