Instrument transformers are electromechanical devices that transform high voltages or currents to lower, standardized values, allowing safe and accurate measurement, protection, and monitoring of electrical systems.

2.1. Types of Instrument Transformers

1. Current Transformers (CTs):
• Reduce high currents to standardized low currents (typically 1A or 5A).
• Used in energy meters, relays, and control systems.
2. Voltage (Potential) Transformers (VTs/PTs):
• Convert high voltages to standardized lower voltages (typically 100V or 110V).
• Enable voltage monitoring and protective relaying.
3. Combined Instrument Transformers:
• Integrate CT and VT in one unit.
• Ideal for space-constrained or compact installations.
