🧭 Overview

ABB Instrument Transformers are essential for the accurate measurement, protection, and control of power systems in high-voltage (HV) and extra-high voltage (EHV) networks. Designed for voltages up to 765 kV, they are engineered to provide precise voltage and current feedback, enabling the secure operation of substations, switchyards, and industrial power grids.

Whether you need current transformers (CTs), voltage transformers (VTs or PTs), or combined units, ABB’s wide range of oil-insulated, SF₆ gas-insulated, and dry-type instrument transformers ensures reliability, safety, and top-tier performance.
