The meter can measure all electrical parameters such as voltage, current, active power, 

reactive power, apparent power, power factor, frequency, 31

st

 harmonic and total harmonic. The 

value format of voltage, current, frequency and power are listed as below. 

Example: U = 220.1V

f = 49.98Hz,    I = 1.99A

P = 0.439kW 

7.2 

计量功能

  Calculating 

能计量当前组合有功电能,正向有功电能,反向有功电能,正向无功电能,反向无功

电能。

 

The meter can calculate the current active energy, forward active energy, reversing active 

energy, forward reactive energy and reversing reactive energy. 

7.3 

分时功能

  Timing 

两套时段表,一年可以分为

4

个时区,每套时段表可设

8

个日时段,

4

个费率

(F1

F2

F3

F4

即尖峰平谷

。分时计费的基本思想就是把电能作为一种商品,利用经济杠杆,用

电高峰期电价高,低谷时电价低,以便削峰填谷,改善用电质量,提高综合经济效益。

 

The meter has 2 time lists, and can be divided into 4 time zones per year. Each time list can 

be divided into 8 time periods and 4 tariff (F1

F2

F3

F4). The main purpose of multi-tariff is 

promote the energy efficiency and economic benefits. 

7.4 

需量功能

  Demand 

有关需量的相关概念如下:

 

There are some definitions on demand:   

       

 

Demand 

需量周期内测得的平均功率叫需量

 

The average power in the demand cycle. 

最大需量

 

Maximum demand 

在指定的时间区内需量的最大值叫最大需量

 

The maximum value of demand in a period of time. 

滑差时间

 

Slip time 

从任意时刻起,按小于需量周期的时间递推测量需量的方法,所
测得的需量叫滑差式需量。递推时间叫滑差时间

 

需量周期

 

Demand cycle 

连续测量平均功率相等的时间间隔

也叫窗口时间

 

The time period between two same average value of demand. 

 

缺省需量周期为

15

分钟,滑差时间为

1

分钟。

 

能测量

4

种最大需量即正向有功、反向有功、感性无功、容性无功最大需量以及最大

需量发生的时间。

 

The default demand cycle is 15 minutes, slip time is 1 minute. 

The meter can measure 4 kinds of maximum demand: forward active, reversing active, 

inductance performance reactive, capacitance performance reactive maximum demand and the 

occur time. 

7.5 

历史数据统计功能

  History data statistics 

能统计上

48

月的历史电能(各费率电能)和上

90

日的历史电能(各费率电能)。

 

The meter can record last 48 months or last 90 days history energy in each tariff. 

7.6 

开关量输入输出功能

Switching input and output 

有一路开关量输出,一路开关量输入,开关量输出为继电器输出,可以实现“遥控”和
