Multi functional three-phase phase voltmeterBasic Introduction

The CJVA-30B multifunctional three-phase phase volt ampere meter has the characteristics of an intelligent instrument (measurement/storage/query/output/printing, etc.), and is widely used in the power industry for relay protection, energy metering, anti-theft and other departments. It is also suitable for use in large power consuming enterprises such as chemical, metallurgical, mining, and railway industries.

Main purpose:

Automatically distinguish the positive and negative phase sequence of the line;

Measurement of electrical parameters for power lines;

Detecting the wiring group of transformers and the secondary circuit wiring of relay protection;

Determine the speed of operation of the electricity meter, calculate the correction factor, and collect electricity fees reasonably;

Check the transformation ratio and polarity of low-voltage CT, and whether the nameplate matches the actual object;

Distinguishing between inductive and capacitive circuits;

Can be equipped with a high current clamp meter for power line loss management data collection;

Used as a leakage current meter, etc.

　　Main functions and characteristics of a multifunctional three-phase phase voltmeter

Adopting a 3.4-inch color LED LCD display screen, the color LCD display has a clear and intuitive interface display;

Measure and display three-phase voltage, current, phase, and hexagonal vector diagram; Real time measurement of active and reactive power, apparent power, frequency, and power factor for phase separation and total power;

Measuring phase with a small current of 1.5mA is very suitable for checking the connection status of newly installed users when there is no load after operation;

The instrument has high measurement accuracy and a wide measurement range of 5V～500V/1.5mA～Accurately measure phase within 10A range;

PT and CT transformation ratios can be set and automatically converted into primary side electrical parameters through secondary measurement;

Equipped with a 500A current clamp, it can measure current transformers, display angle difference, ratio difference, and distinguish polarity;

Vector diagram drawing can be set with X axis, Y axis, 12 points, 11 points, and 3 points, suitable for various wiring methods.

Automatically identify the load characteristics of the line, automatically identify 1008 types of wiring errors in three-phase three wire and three-phase four wire electric energy meters, and indicate the location of the errors;

The measurement results can be displayed in various ways such as vector graphics and tables, with multiple parameters displayed on the same screen, making the measurement data clear at a glance;

Dual power supply: direct power supply for the measuring end and high-performance lithium battery power supply; When powered by lithium batteries, the instrument can work continuously for 18-30 hours; Standby time ≥ 60 hours, charging times ≥ 500 times;

Built in memory, capable of storing 200 sets of measurement data, and can view saved data sets and vector graphs;

Automatic power saving management function, which can automatically shut down or enter sleep mode;

Built in clock chip, capable of accurately recording and displaying measurement time;

Support data uploading to computers, allowing for direct browsing, export, editing, printing (A4 format), backup, and other functions of instrument data. It can also be exported as standard EXCEL format files and generate experimental reports;

Implement browsing and querying functions for test results, combining Chinese menus with direct buttons for easy and user-friendly operation;

Humanized design, anti drop wristband to prevent operators from accidentally damaging the instrument;

Adopting an ultra small structural design, handheld, small in size, and lightweight.

Optional high current clamp above 500A can be used to measure the electrical parameters of low-voltage primary lines.

Optional WIFI wireless function and APP power consumption data collection system can be used to synchronously view data and collect real-time data on site on Android terminal tablets or mobile phones, and multiple people can view it simultaneously.
