Product Introduction

ETCR7300 Large Caliber Three Phase Clamp Power Meter, also known as clamp type power meter, super large caliber clamp type power meter, three phase clamp type power meter, which is used for measurement of AC current, leakage current, voltage, phase; active power, reactive power, apparent power, power factor, total power, frequency, phase sequence, electrical energy and other parameter measurement. It can also be used to distinguish transformer wiring group, inductive and capacitive circuit, figure out the phase relationship between different CT groups of differential protection, check the correctness of the wiring of the electricity meter, repair line equipment, etc., providing a safe, accurate, and convenient new type of power meter for electricity inspectors. The clamp of ETCR7300 Large Caliber Three Phase Clamp Power Meter is made of Slope film alloy material, adopting with double shielding technology without the influence of external magnetic field , which is ensuring uninterrupted measurement of high precision, high stability and high reliability all year. Large caliber clamp(80mm×80mm) is exceedingly useful, the meter can store 200 groups data and the storage data can be uploaded to computer via USB interface and system software, which achieving reading, saving, printing and other functions of historical data.
1.Large caliber clamp jaw 80mm×80mm (can clamp φ80mm electrical cable, or 96mm×4mm flat steel ground wire), convenient to use.
2.It can be used to measure leakage current.
3.Memory: data storage 200 groups
4.USB communication interface
