The MEWOI7900 Rogowski current clamp is designed for the test of big current and leakage current. It is widely used in the fields of electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and so on. The cable is especially suitable for intensive places, the current industrial environment such as the wall- subway transformer core current test, thick wire cable test, relay protection, silicon controlled rectifier, inverter, semiconductor switch, power electronic conversion equipment, arc welding and other serious distortion of the signal of the test.
Flexible current clamp, namely Rogowski Coil (Rockwell coil), is a circular coil uniformly wound on non-ferromagnetic materials, no hysteresis effect, almost zero phase error, no magnetic saturation, high linearity, 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 truly restored, and the current range can be from mA to 10000A. Flexible coil current clamp part without any bare metal conductor, non-contact measurement, safe and fast; the small size and light weight, beautiful appearance, soft and flexible, suitable for narrow environment and cable intensive sites; high accuracy, strong reliability, frequency bandwidth, users can be customized according to the length of the coil.
The instrument also has the functions of peak retention, data retention, data storage and so on. It is a necessary tool for electrical safety inspection.
