Instrument transformers are devices used to transform high-voltage and high-current electrical signals to lower levels, making them suitable for measurement, protection, and control applications. These transformers are crucial in power systems, allowing for the safe and accurate monitoring of electrical parameters. Instrument transformers are broadly categorized into two types: voltage transformers (VTs) and current transformers (CTs).
