Does an ungrounded system have a grounding conductor?

No, an ungrounded system does not have a grounding conductor. The purpose of a grounding conductor is to connect the electrical system to the earth, which is not the case in an ungrounded system. In an ungrounded system, there is no intentional connection between the electrical conductors and earth ground. This can lead to potential safety risks, such as electrical shock if a person comes into contact with the ungrounded system. Therefore, while an ungrounded system does not have a grounding conductor, it is generally recommended to ground electrical systems for safety reasons.
