Specialized Three-Phase Four-Wire Integrator for Electric Energy Meters with Piercing Power Taps Flexible Rogowski Coil
The flexible Rogowski coil current sensor enables precise measurement of alternating current while providing electrical isolation between the primary and secondary circuits. Its advanced winding technology significantly reduces positional errors of the measured conductor within the aperture, enhancing the sensor's immunity to external magnetic interference.
