Product Overview

Due to the frequent wiring of protective devices and high-voltage metering devices, it is easy to cause incorrect wiring that is not easily detected (especially for the complex wiring of differential protection, sometimes both high and low sides are introduced simultaneously, and there are different connection groups, which are prone to misconnection, and may not cause misoperation or refusal to operate during normal operation, posing a great hidden danger). Our company has timely developed a multifunctional vector analyzer based on on-site testing needs. The measuring instrument adoptsDSP AC sampling can simultaneously measure 8 channels of voltage (two channels A, B, C, N) and 8 channels of current (two channels A, B, C, N) analog signals. The instrument displays 12 channels of vectors on the same screen and has a user-friendly human-machine interface; The independently developed handheld structure, made of high-strength engineering plastic, is sturdy and lightweight, easy to use, and greatly facilitates on-site use, making it a reliable assistant for power workers.

Features

lEight voltage and eight current vectors displayed on the same screen; The testing of differential protection devices only requires one wiring to complete the drawing of the hexagonal diagram, greatly improving work efficiency; In situations where space is small and wiring is difficult, the double clamp method can be used for multiple measurements to ultimately draw a complete hexagonal diagram.

lUsing clamp type current transformers for wiring, there is no need to disconnect the current circuit, which is safe and convenient.

lVector analysis of complex protection devices (including main transformer differential protection and bus differential protection) can be carried out to determine whether the wiring is correct, and the correct wiring diagram can be provided for comparison.

lcan be performedPT parallel vector inspection to avoid PT secondary wiring short circuit.

lIt can perform routine electrical parameter testing and display four phase voltage, four phase current, three-phase active power, three-phase reactive power, three-phase apparent power, and three-phase phase angle simultaneously; And it can directly read and convert the voltage amplitude, current amplitude, and power values to the primary side of the transformer.

lCan perform wrong wiring inspection for three-phase three wire high voltage metering devices, capable of detecting three-phase three wire faults192 types of wiring are analyzed and judged, and the analysis results are directly provided; Investigating and punishing malicious methods of electricity theft that alter metering wiring, effectively avoiding electricity bill losses.

lCan conduct harmonic analysis of the measured signal on site, capable of analyzingAutomatically calculate the total harmonic distortion based on the content of each order of 2-64 harmonics.

lTrue Color10 inch large screen LCD display with a resolution of 1280 × 800;

lCapacitive screen touch operation, similar to tablet and smartphone operation, simple and easy to learn;

lPowered by a large capacity lithium battery, it can work continuously for up to8 hours.

lUsers can save the test data in the form of records at any time for centralized and unified management, filing, and reference, and can store itMore than 200 sets of data.

lThe saved records can be uploaded to the backend management computer for comprehensive analysis and review.

lEquipped with perpetual calendar and clock functions, it displays the date and time of the testing work in real time.

lSmall size, light weight, easy to use on site.

lreserveUSB interface can be used as a substitute for USB drives and other mobile storage devices with instruments.
