INTRODUCTION
TesterMeter-ETCR7350 flexible clamp power meter is a specially developed by our company for on-site measurement of three-phase AC voltage, current, phase between voltage, phase between voltage and current, frequency, phase sequence, electric energy, active power, reactive power, Multifunctional, digital smart meter for apparent power, power factor, total power, etc. The clamp meter adopts flexible Rogowski coils, which is very convenient to use and is fully compatible with the functions of large-diameter clamp ammeters and power clamp meters. The phase relationship between them, check whether the wiring of the watt-hour meter is correct or not, and repair line equipment, etc., provide a safe, accurate and convenient new type of power meter for electricity inspectors. The flexible current clamp , Rogowski Coil (Rogowski coil), adopts advanced Rogowski coil technology, which is a toroidal coil uniformly wound on non- ferromagnetic materials , without hysteresis effect , almost zero phase error, no magnetic saturation phenomenon, linear High accuracy, strong anti-interference ability. 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 measured current range can range from milliamps to tens of thousands of amperes. The coil part of the flexible current clamp does not have any exposed metal conductors, non-contact measurement, safe and fast; it is small in size, light in weight, beautiful in appearance, soft and flexible, suitable for narrow environments and places with dense wiring; high measurement accuracy, strong reliability, The response frequency is wide, and users can customize the coil length according to their needs. TesterMeter-ETCR7350 flexible clamp power meter is small in size and light in weight. It is very convenient and easy to operate on site and has high measurement accuracy. The instrument has a USB communication interface and can store data. Upload the stored data to the computer through the system software to realize historical data reading and query. , save, print and other functions. The instrument also has a backlight function and a data retention function, which is an essential tool for electrician safety testing. |
