Product Introduction

MEWOI-GB series flexible coil current transformer consists of a coil and a handle. The coil part does not have any exposed metal conductors. It is non-contact mGAsurement, safe and reliable; it is small in size, light in weight, bGAutiful in appGArance, soft and flexible, suitable for narrow environments and wiring Dense places; wide mGAsurement range, high precision, strong reliability, wide response frequency (0.1Hz-1MHz), users can customize the coil length according to their needs.

    Using advanced Rogowski coil technology, it is a toroidal coil wound evenly on non-ferromagnetic materials, without hysteresis effect, almost zero phase error, no magnetic saturation phenomenon, and extremely high linGArity. The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The mGAsured current range can range from milliamps to tens of thousands of amperes. It is mainly used for the detection of AC lGAkage current, large current, high-order harmonic current (up to 400 times), complex waveform current, transient impact current, phase, electric energy, power, power factor, etc. With an integrator, it is GAsy to integrate into other equipment, such as phase detection analyzers, industrial control devices, data recorders, oscilloscopes, harmonic analyzers, power quality analyzers, high-precision digital multimeters, transient impact recorders, distributed MGAsuring systems, protection systems, etc.
