What is the voltage between C phase and ground in a 240-volt corner-grounded delta?

In a 240-volt corner-grounded delta system, one of the phases (in this case, the C phase) is connected to ground, establishing it as a reference point for the system. Since this phase is grounded, the voltage between C phase and the ground is 0 volts.

In a corner-grounded delta system, the phase that is grounded does not have a potential difference with respect to the ground, meaning that any measurement taken from that phase to ground will yield zero volts. The other phases (A and B) in this system can have voltage readings relative to ground, typically showing 240 volts or other values depending on the configuration and the specific phase being measured. Thus, the ground serves as a safety and reference point without contributing to voltage between the grounded phase and ground itself.
