Electrical Features of the Queen Mary

Perhaps this has been answered elsewhere, but I haven't found it:

What was the original electrical voltage aboard the QM? If I remember correctly, the Titanic's was at about 100v DC. I was very surprised to learn this, and so I wonder if that was a standard (for ships) at the time? Did the QM have the same voltage flowing through her veins?
