The full form of CTPT is Current Transformer Potential Transformer.
According to the provided reference:
Among the multiple components and devices used in an electrical system, the CT PT Junction Box is a type of transformer used in high-voltage electrical systems. The term CT here stands for Current Transformer and PT stands for Potential Transformer.
Therefore, in the context of electrical systems, particularly high-voltage systems, CTPT refers to the combination of current and potential transformers.
