PD810-B5L系列-测试电力参数方法

      The improvement of power system automation makes intelligent and high precision become the basic requirements of modern multi-function power meters. Most of the design schemes widely used in traditional power meters have problems such as hardware design difficulties, large data processing by software, and low measurement accuracy.
       A smart meter designed for power monitoring needs of power systems, industrial and mining operations, etc. As an intelligent and digital front-end collection element, it is used in various control systems and energy management.
 
        Disadvantages of traditional instruments:
In the original power system, a variety of mechanical instruments (such as watt-hour meters, ammeters, voltmeters, etc.) are often installed in high- and low-voltage power distribution cabinets to monitor the power system. It is time to go to all instrument points for manual meter reading to provide a data basis for future data analysis and processing. In this working mode, due to the installation of a large number of complicated instruments, the production operation cost and labor cost are greatly increased, and the work efficiency is low, and it is prone to record errors.
 
        Advantages:
Because not only can be used in one table, but also can realize the functions of programming settings and data collection of the instrument by the host computer or handheld programmer through its communication interface, the use of multi-function network power meters can be greatly reduced Labor costs, reduce operating costs, and can greatly improve work efficiency. At the same time, the meter has perfect communication networking function, which is very suitable for real-time power monitoring system. It can be used locally or form a high-performance telemetry remote control network through the field bus.

■ 功能特点
仪表可监测下列电能质量参数：
- 畸变率与谐波含量
可测量三相电压、电流的谐波畸变率；2-31th 谐波含量（通过通信读取）。
- 波峰系数
波峰系数是电压的峰值与平均值的比值。
- 电流K 系数
K 系数是描述供电给非线性负载变压器额外发热的参数，反映变压器承受谐波时所额外温升的能力。
- 不平衡度
指三相电力系统中三相不平衡程度。用电压、电流负序基波分量或零序基波分量与正序基波分量的方均根值的百分比表示。根据对称分量法，三相系统中的电量可分解为正序分量、负序分量和零序分量三个对称分量；本仪表采用负序基波分量与正序基波分量均方根值的百分比。
