ETCR7350 Flexible Coil Clamp Power Meter is a multi-functional, digital and intelligent instrument, which is specially designed and manufactured to measuring for the field measurement of three-phase ac voltage, current, leakage current, phase between voltage, phase between voltage and current, frequency, phase sequence, electric energy, active power, reactive power, apparent power, power factor and total power and so on, the clamp with large caliber (80mmX80mm: can clamp an test φ80mm cable, or 96mmX4mm flat steel grounding leads), convenient to use, fully compatible with the functions of large caliber clamp leakage current meter and micro-power clamp meter, also can be used to distinguish transformer connection group, sensibility,capacity circuit, reading out the phase relationship between with every groups differential protection CT , check the watt hour meter wiring correctly or not, maintenance line equipment, etc., providing a safe, accurate and convenient new type power meter to the electricity inspection personnel.

Flexible current clamp sensor,also name Rogowski Coil, adopts advanced Rogowski Coil technology, which is a loop coil uniformly wound on non-ferromagnetic materials, with no hysteresis effect, almost zero phase error, no magnetic saturation, high linearity and 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 ranges from milliamperes up to ten thousands ofamperes. Flexible coil without any exposed metal conductor, non-contact measurement, safe and reliable. Small size, light weight, soft and flexible, suitable for narrow environment and flat cable dense places. High measurement accuracy, strong reliability, wide response frequency band, the user can customize the coil length according to demand.

ETCR7350 Flexible Coil Clamp Power Meter is small size and light weight, very portable and simple in field operation. The meter has USB communication port, can store data and through the system software to upload the stored data to the computer, which can read, query, save, print and other functions of historical data. The meter also has backlight and data hold function, which is the necessary meter of electrical safety testing.
