Reactive energy regulator MASTER control Var
MASTER无功控制器
The MASTER controller combines the functions of power factor controller, mains analyzer and protective device in a single device.
MASTER控制器将功率因数控制器、电源分析仪和保护装置的功能结合在一个装置中。
MASTER controller has a built in power analyzer allowing the measurement of main electrical parameters (voltage, current, harmonics, active and reactive power, apparent power, etc.).
MASTER控制器具有内置的功率分析仪，可以测量主要电气参数（电压、电流、谐波、有功和无功功率、视在功率等）。
The device gives a detailed information on both, voltage and current harmonic components. MASTER controller measures also ambient temperature and keeps a record of maximum and minimum values of all measured parameters. All this information as analyzer is possible by using 1 or 3 current measurement transformer.
该装置给出了关于电压和电流谐波分量的详细信息。MASTER控制器还测量环境温度并保持所有测量参数的最大值和最小值的记录。所有这些信息都可以通过使用1至3项电流测量变压器的数据作为分析依据。
Serial Communications
串行通信
MASTER controllers are equipped with RS-485 communication with MODBUS protocol. This allows the integration of the PF regulator in a data network driven by a computer (PC). Enables data recording, remote control, supervision and preventive maintenance of the PF correction equipment itself and of the whole LV network.
MASTER控制器配备有与MODBUS协议的RS-485通信。这允许PF调节器集成在由计算机（PC）驱动的数据网络中。能够对PF校正设备本身以及整个LV网络进行数据记录、远程控制、监控和预防性维护。
AUTO-ON-OFF Function
自动开关功能
This function allows to define the operating mode of each individual capacitor step:
该功能允许定义每个单独的电容器的操作模式：
- Automatic mode (Auto).
自动模式（自动） - Fixed mode (ON): Capacitor is always ON.
固定模式（开）：电容器总是开着。 - Disconnected mode (OFF). Capacitor is always OFF.
断开模式（关）。电容器总是断开。
Plug and Play
即插即用
A series of parameters must be configured when a power factor regulator is installed, to make sure that it operates correctly. Some of these parameters might be hard to know, such as, for example, the voltage phases or the voltage corresponding to the current measured, as well as the current transformer ratio. MASTER has been designed with a smart automatic process that detects the necessary parameters, such as:
在安装功率因数调节器时，必须配置一系列参数，以确保其工作正常。这些参数中的一些可能难以获取，例如，电压相位或与测量电流相对应的电压以及电流互感器比。MASTER控制器已经设计了一个智能的自动过程，检测必要的参数，如：
- C/K: calculates the ratio of the current transformer and the power of the smallest step.
C/K：检查、计算电流互感器的比和最小阶的功率。 - Phase: Identifies the voltage sequence and correspondence with current. In other words, it identifies the UL1, UL2, UL3 , when the current measured is IL1, IL2, IL3 and whether it is connected in the opposite way or not.
相位：识别电压序列和电流的对应关系。换句话说，它识别UL1、UL2、UL3，当测量的电流是IL1、IL2、IL3以及它是否以相反的方式连接。 - Number of stages installed and Program: the system connects all stages in a sequence, finds out how many stages are installed and then calculates the program, i.e., the power ratio of the capacitors.
安装级数和流程：系统按顺序连接所有级，找出安装了多少级，然后计算流程，即电容器的功率比。
Built-in leakage control
内置漏电控制
MASTER have a built-in circuit to measure the earth leakage current through a WGC transformer. The regulator is able to measure the individual leakage of each capacitor. This allows to disable a damaged capacitor if an excess of leakage current is detected without interrupting the supply service.
MASTER有一个内置电路来测量通过WGC（环形）变压器的漏电电流。该调节器能够测量每个电容器的单独泄漏。这允许在没有中断供电服务的情况下检测到过量的泄漏电流来禁用损坏的电容器。
