WebWhat is the PT Ratio: Just like the CT par ratio is written, the ratio is also written on it which is called the PT ratio. Example: 1000/5 as CT converts 1000A to 5A. So PT also has a ratio. If a PT cross is written as 11000/110 then this means that PT gives us 110 out of 11000 Voltage output. Difference between CT and PT: Websignal to noise ratio.
