Protection Circuit Vector Analyzer

Protection Circuit Vector Analyzer

main feature

5.7 -inch large-screen color LCD display, the original PDA color vector diagram and the various phase measurement parameters, dual-color display intuitive. The operating status and test parameters of the Chinese character display instrument can be combined with the Chinese menu and the direct key operation. It requires easy-to-learn, easy-to-use, integrated functional architecture that eliminates the need to connect to cumbersome PDAs . The instrument can measure 1~4 AC voltages and 1~6 6 -stream currents at the same time. Measure two turns of YY and Y △ differential protection secondary current wiring, and can synthesize the phase angle relationship and vector diagram, to facilitate the relay protection staff to distinguish between the two laps to change the six-phase current or three-phase change nine-phase current Relationship, polarity, and difference flow. Six current input signals, Ua voltage can be used as a reference, while high-side currents ( IA , IB , IC ) and low-end currents ( Ia , Ib , Ic ) can be detected at the same time ; voltage and current ( UI ) and voltage at the high and low voltages can be displayed in the same segment at the same time . The phase relationship between the voltage ( UU ), current and current ( II ), the hexagonal vector diagram of the six currents in the same screen and the polarity discrimination. The minimum selectable 1mA current can accurately measure the phase, which can be used to check the wiring in the field when the new user is no longer loaded after power transmission. The instrument can directly measure the phase relationship of the six currents when the voltage signal is not connected. And can measure the zero-sequence current ( 3I0 ). It can measure and display the voltage, current, phase relationship and vector diagram of each phase of the three-phase system on the same screen; it can measure the active power, reactive power and apparent power of each phase of the three-phase system in real time, and the total power of the three-phase system ( Σ P , Σ Q , Σ S ), power factor, frequency, etc. It can easily detect the three-phase power load balance status, and there is a Chinese character phase sequence state. The main transformer differential protection analysis and bus differential protection analysis can be conveniently performed and conclusions can be given. The instrument has a built-in vector calculator that calculates the vector sum of high and low currents, and calculates and displays vector angles. The built-in clock chip of the instrument can accurately record and display the measurement time and facilitate data query management. The instrument can be equipped with a 500A clamp-type current transformer for detecting the ratio (angle difference, ratio difference) and polarity of the current transformer. Instrument power supply for dual power supply: AC measurement terminal AC45V ~ 450V direct power supply; can switch to the built-in lithium battery power supply. The power management function can be set when the battery is powered, and the automatic shutdown time or the instrument sleep state can be set. The instrument has built-in large-capacity memory, which can save all measurement data and 200 group of hexagonal vector diagrams , and can directly check the saved data group and vector diagram through the panel operation keys. The instrument is equipped with a communication interface, which can upload the instrument measurement data in groups to the PC , to upload or analyze test results or browse, query, report output, and data print. The instrument is designed according to the ergonomics ultra-small structure, hand-held, small size, light weight. Anti-shedding wristbands are also provided to prevent the operator from accidentally damaging the instrument.
