Product Introduction

ETCR4480 Wireless Three Phase Phase Voltmeter, also known as three-phase power parameter tester, CT load tester, PT load tester, is used for three-phase power parameter measurement, PT wireless nuclear phase, PT load test, CT load test, three-phase imbalance test, harmonic analysis, etc. at different locations in the substation.The instrument consists of 2 handheld terminals, 6 current pliers, 2 sets of voltage test lines, etc. The 2 handheld terminals have wireless communication and GPS communication, and can be set as host or slave to each other to achieve synchronous measurement of current, voltage, phase and other parameters between different locations in the substation. When a single handheld terminal is used, it is used as a three-phase phase voltammeter, which can measure current, voltage, phase, power, frequency, power factor, three-phase imbalance and other parameters and harmonic analysis, and can display vector diagrams of three-phase voltage and three-phase current in real time.When used as a load tester, it can measure the voltage, current, conductivity, admittance, frequency on the PT side, and the voltage, current, resistance, reactance, frequency and other parameters on the CT side. When two handheld terminals are used at the same time, through wireless communication and GPS satellite timing technology, six voltage amplitudes, phases and other parameters can be measured simultaneously at different locations in the substation.Wireless PT nuclear phase can be performed.When the two instruments are turned on at the same time, it is possible to set the wiring type, communication channel, master-slave switching, time setting, etc. in linkage. When four handheld terminals are used at the same time, one of them can be set as the host and the other three as the slave, which is particularly suitable for multi-point synchronous measurement, flexible field application, and more convenient testing.
ETCR4480 Wireless Three Phase Phase Voltmeter adopts a 5-inch touch color screen, Chinese interface, direct function, automatic measurement, easy and fast operation, accurate and reliable, the instrument adopts large-capacity rechargeable lithium battery, with data storage, data access, automatic shutdown, USB interface data upload and export functions.The meter has Bluetooth communication that supports the Android system, and it can be tested on the mobile phone or view the test records.This instrument adopts a special metering chip, which has very high electrical parameter measurement accuracy, can display changes in the parameters to be tested in real time, and has the function of saving data with one key.The product is simple to operate, easy to use, fast measurement, stable, and reliable results. It is a new generation of instruments that specialize in electrical energy metering and relay protection of power systems and conduct on-site testing of secondary circuits. It is also widely used in electrical equipment manufacturing, petrochemical industry, iron and steel metallurgy, railway electrification, scientific research and teaching and other departments.
