Overview
ETCR4300 Three-phase Digital Phase Voltammeter is a multifunctional, digital and intelligent instrument specially developed by our company for field testing. It has the characteristics of high accuracy, high stability, low power consumption and convenient to use etc. Under the condition of the tested circuit does not open-loop, it can measurement of three-phase AC voltage, current, phase between voltages, phase between current, phase between current and voltage, frequency, phase sequence, active power, reactive power, apparent power, power factor, current vector sum, judge transformer wiring group, sensibility and capacitive circuit, test the secondary circuit and differential bus protection system, read the phase relationship between differential protection between each groups CT, check watt hour meter wiring correctly or not, maintenance line equipment, etc., to provide a safe, accurate and convenient new power meter for electricity inspectors.
ETCR4300 Three-phase Digital Phase Voltammeter with shake proof, skid proof, and high insulation sheath. Adopts 2.8 inch color LCD screen, dynamic display, vector diagram indication, clear and obvious, which shows the exquisite and luxurious appearance. Its sharp and small shape current clamp is suitable for the place where the wires arranging are dense.
ETCR4300 Three-phase Digital Phase Voltammeter also name intelligent three phase digital phase voltammeter, multifunction three phase digital phase voltmeter and three clamp digital phase voltmeter etc. Suitable for electric power, petrochemical, metallurgy, railway, industrial and mining enterprises, scientific research institutions, measurement departments. It is especially suitable for electric energy billing system and relay protection system.
