CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It steps down high grid voltages to safe, standardized low-voltage signals for monitoring, protection, and metering equipment, providing isolation and accurate measurement.
Select based on the grid voltage class where the transformer will be installed. The rated primary voltage should match the system voltage, typically in the range of 3–35 kV as per IEC 61869-3.
Accuracy class depends on the application: 0.2 for metering, 3P for protection. Refer to IEC 61869-3 and verify with the manufacturer for specific requirements.
Regular inspection of insulation integrity, checking for oil leaks (if oil-insulated), and verifying secondary wiring and burden. Periodic accuracy testing is recommended. Always follow manufacturer guidelines.
