Global Instrument Transformer Market – Industry Trends and Forecast to 2032

Instrument transformers are essential components used in power systems to safely and precisely measure high voltage and high current levels by scaling them down to standardized, manageable values for metering and protection. Two primary types are:

Current Transformers (CTs) – Reduce large currents to a safe, proportional secondary current, allowing accurate current measurement and reliable circuit protection.

Voltage (Potential) Transformers (PTs) – Step down high voltages to standardized, lower-level voltages for feeding metering devices and protective relays.

These devices ensure electrical isolation, minimize risk, and maintain measurement accuracy within electrical grids—from substations and power plants to industrial facilities.
