Features 1、Using high quality coil technology, it is a toroidal coil that is evenly wound on non ferromagnetic materials, with no hysteresis effect, almost zero phase error, no magnetic saturation, and extremely high linearity. 2、True restoration, it can truly restore the input current by integrating the output voltage signal, and its measurement current range can be from milliampere level to tens of thousands of amperes. 3、Multi function, it is mainly used for the detection of AC leakage current, high current, high order harmonic current (up to 400 times), complex waveform current, transient inrush current, phase, electric energy, power, power factor, etc. 4、High accuracy, wide measurement range, strong reliability, response frequency bandwidth range of 0.1Hz‑1MHz, it has high practicability. 5、Safety design, it is composed of coil and handle, without any exposed metal conductor, can be used for non contact measurement, small and light weight, suitable for narrow environment and densely arranged places. Specification Item Type: Transformer Model: ETCR300FA Material: ABS Purpose: It can be equipped with an integrator and is easy to integrate into other equipment, such as phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high accuracy digital multimeters, transient shocks Recorders, distributed measurement systems, protection systems, etc. Function AC leakage current, high current, high order harmonic current, complex waveform current, transient inrush current, phase, electric energy, power, power factor, etc. detection. Detection Method Flexible coil CT: The output signal is the differentiation of current with respect to time. By integrating the output voltage signal, the input current can be truly restored.
