FR2050 series flexible clamp power meter is a multi-function digital smart meters that specially developed by our company for measuring three-phase AC voltage, current, leakage current, phase between voltage, phase, frequency, phase sequence, electric energy, active power and reactive power, power, apparent power, power factor, total power, etc. The use of flexible coil sensors with a diameter of φ150mm or φ300mm (other diameters can also be customized) is convenient and flexible, and can replace the traditional bulky clamp-type leakage current meter and micropower clamp meter function. It can also be used to identify transformer wiring groups, inductive, capacitive circuits, read the phase relationship between the CTs of the differential protection groups, check the correctness of the wiring of the watt-hour meter, and repair the line equipment, etc, provides a safe, accurate and convenient new type of power meter for electricity inspection personnel.
The flexible current sensor, Rogowski Coil, adopts advanced Rockwell coil (or Rogowski coil) technology and is a toroidal coil uniformly wound on a non-ferromagnetic material, without hysteresis effect and without magnetic saturation phenomenon. High linearity, strong anti-interference ability. The output signal is the current-to-time differential. By integrating the output voltage signal, the input current can be truly restored. The measured current range can be from milliampere to tens of thousands of amps. Flexible current clamp part without any exposed metal conductor, non-contact measurement, safe and fast；Its small size, light weight, exquisite appearance, soft and flexible, suitable for narrow environments and cable intensive places；High measurement accuracy, high reliability, and response frequency bandwidth, users can customize the coil length according to demand。
The instrument also has the function of backlight, data retention, data storage, etc. It is easy to use and is an essential tool for electrician safety testing.
