Reactive energy regulator MASTER control Var
高压MASTER无功控制器
Description 概述
Measurement with three current transformers guarantees an analogue reading of the company’s meter. The Master control Var reactive energy regulator is the only regulator in the market that offers the possibility of using 3 measuring transformers in addition to the traditional method of measuring with a single current transformer, as well as providing the functions of an integral power analyzer and controlling the residual leakage currents.
三个电流互感器的测量保证了仪表的模拟读数。MASTER Var无功功率控制器作为市场上传统的使用一个电流互感器无功功率控制器的补充，使用了3个测量变压器。同时提供完整的功率分析仪的功能和控制残余泄漏电流的方法。
Master control Var is a regulator that guarantees excellent preventive maintenance operations by means of programming its alarms and the test options of the capacitor status, offering the maximum supervision and safety of your compensation unit.
Master VAR控制器是保证良好预防性维护的控制器，通过设定其警报和电容器状态的测试选项的操作，
为你的补偿单元提供最大程度的监督和安全。

The connection of 1 or 3 transformers makes Master control Var the perfect regulator in any installation, allowing the following:
1个或3个变压器的连接使得Master控制器在不同安装系统中都是合适的控制器，允许如下应用：
- Changing from 1 to 3 transformers in the following cases:
在下列情况下从1变压器变为3变压器：- Changes in reactive energy penalties
无功补偿的变化 - Changes in consumption habits
消费习惯的变化 - Significant imbalances in the system
系统的重大失衡
- Changes in reactive energy penalties
- Replacing the regulator of any capacitor bank
更换任何电容器柜的控制器 - Perfect for installations with up to 4 objective cosφ, since it can adapt to any compensation need (different time periods).
Perfect for installations with up to 4 objective cosφ, since it can adapt to any compensation need (different time periods). 适用于多达4个目标功率因素的安装，因为它可以适应不同补偿需要（不同的时间段）。 - It can be used with Medium Voltage compensation units.
