Precision high-current transformer --------- Rogowski coil current transformer

Applications: Based on Rockwell coil with a current real-time measurement, fast response, not saturated, almost no features of the phase error, so it can be applied to the relay, thyristor rectifier, inverter, resistance welding serious signal distortion occasions. Rated current (rms) 1 ~ 20000Aac output 0-100mv (without integrators) 0 ~ 5Vac (with integrator) Rogowski coil length 20cm ~ 200cm optional lead shield wire leads, lengths isolation voltage 3500V Temperature range -25 ℃ to + 70 ℃ response bandwidth of 1Hz to 1MHz accuracy of ± 1% (flexible coil) ± 0.2%, ± 0.5% (rigid coil)
