低压三相交流系统由三相火线L1、L2 和L3 以及中线N 组成。中线连接到发电机或变压器二次侧中性点上。单相交流系统可单独由两相火线组成，或者由一相火线和中线组成。
工作电压
两相火线（L1、L2 和L3）之间的电压是线电压（或系统电压）。一相火线和中线之间的电压是相对中线电压（或相电压）。三角形连接时，线电压就是相电压

Project database
All configured signals, variables and process points are in Freelance
800F system’s public database for management.
● List of all variables (input, output, internal variables)
● Process point list (function block)
●Graphics
●Program
Because the database is system-wide. The data only needs to enter a
times, to avoid possible errors caused by multiple configurations.
Project database files can be easily archived or backed up.
When programmed by the user, a list of variables and labels is automatically created.
Moreover, both variables and process points can be opened and closed directly in FBD or IL
Revise.
List other features include:
Project-wide modification of names, comments, data or module types
●Search and display based on specific criteria
● Cross reference can be used in systems that use a large number of variables or process points
Programs and drawings to quickly find the desired variable or process point within the scope

ABB is the world’s largest in measurement and process automation
One of the equipment and system suppliers.
An important factor in maintaining this market position is the quality of our products
quantity, and quality from manufacture all the way to service. ABB automation early
In 1990, it obtained the DQS certificate based on ISO9001 certification,
EQnet quality based on ISO 9000/EN 29000 was subsequently achieved
Certification.
However, the Freelance 800F is more than technical excellence, I
We have also spent a lot of effort in proper planning, installation and revision too
This makes engineering design and maintenance faster, more economical and
