Potential Transformer

IEC 60044-2 potential transformers reduce high primary voltages to standardized 100V/110V – enabling precision metering and stable grid protection.

  • Steps down dangerous high voltages to safe, measurable levels for instruments and control devices.
  • Supplies accurate voltage signals to billing meters and protection relays, ensuring correct tariff and reliable fault isolation.
  • Customizable primary/secondary ratios and accuracy classes (0.2/0.5/3P) for substation and distribution network needs.
