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

Tell me in detail about c.t. And p.t. ?
What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
