What characterizes the IT grounding method?

The IT grounding method is characterized by having no direct connection to ground in the distribution system. In this setup, the supply system is isolated from the ground, meaning that there is no intentional connection made to earth ground. This method is often used in certain industrial settings because it can help enhance operational safety and minimize the risks associated with ground faults.

By not having a direct grounding point, the system can continue to operate safely even if one phase develops a ground fault, as long as proper protective measures are followed. This isolation allows for the identification of faults without disruption to the entire electrical system, making it advantageous in scenarios where continuous operation is critical.
