Flexible coil high current recorder is carefully designed and manufactured for on-line testing, monitoring, recording AC current, leakage current, waveform and frequency. It is composed of host, flexible coil, software and communication lines. It is widely used in electric power, communication, meteorology, railway, oil field, construction, metrology, scientific research and teaching units, industrial and mining enterprises and other fields. It is especially suitable for current testing in industrial environments where the signals are seriously distorted, such as densely arranged wires, transformer grounding core current testing near the wall, thick wire cable testing, relay protection, thyristor rectifier, frequency conversion speed regulating, semiconductor switch, power electronic conversion equipment, arc welding and so on.

Flexible coil, Rogowski Coil (Rogowski Coil), using advanced Rogowski coil (or Rogowski coil) technology, is a circular coil wound evenly on non-ferromagnetic materials. It has no hysteresis effect, almost zero phase error, no magnetic saturation phenomenon, extremely high linearity and strong anti-interference ability. The output signal is the differential of current to time. By integrating the output voltage signal, the input current can be restored. The measuring current range can be from milliampere to tens of thousands amperes. Flexible current clamp coil part has no bare metal conductor, non-contact measurement, safe and fast; its small size, light weight, exquisite appearance, soft and flexible, suitable for narrow environment and places with dense wire arrangement; high measurement accuracy, strong reliability, wide response frequency bandwidth, users can customize the length of coil according to their needs.

Host LCD display, clear at a glance. At the same time, it has relatively large storage space, can store 6000 groups of data, and also has the function of automatic storage interval setting, which can be set from 1 to 60 minutes.
