CT- Current Transformer.
Its primary side is always connected in sereis with the
supply system . It normally steps down the current from high
value to low value.
PT- Potential Transformer.
Its primary side is always connected in parallel to the
supply system.It normally steps down the voltage from high

CT & PT are called instrument transformers and used for
metering and protection purpose.
