Instrument transformers are specialized electrical devices designed for current and voltage measurement as well as power system protection. Widely applied in substations, industrial plants and power grids, they accurately transform high currents or voltages into standardized low values, enabling safe operation of meters, relays and other control equipment.
Our instrument transformers feature low power loss, high precision and excellent thermal stability, meeting international standards like IEC 61869. Available in current transformer (CT) and voltage transformer (VT) types, they support customizable specifications for different voltage classes (10kV–500kV) and load requirements. Ideal for energy management, fault detection and power quality monitoring, these transformers ensure reliable performance in harsh working environments.
As core components of electrical systems, instrument transformers play a vital role in safe measurement and efficient protection. Unlike ordinary transformers, they provide isolated, accurate signal conversion for high-voltage circuits, protecting personnel and equipment from overvoltage or overcurrent hazards.
Our premium instrument transformers boast robust construction, long service life and easy installation. With strict quality control from raw material selection to final testing, they deliver consistent accuracy even under fluctuating load conditions. Suitable for utility companies, transformer manufacturers and engineering projects, our CTs and VTs help reduce maintenance costs and improve overall system efficiency. Custom solutions are offered to meet unique project needs.
