描述
使用三个电流互感器进行测量可确保模拟读取公司的仪表。主控制器无功功率控制器是一种除了传统的单电流互感器测量方法外，还可以使用3个测量变压器的控制器，并提供集成功率分析仪的功能和控制剩余泄漏电流。
主控制Var是一种控制器，通过编程其报警和电容器状态的测试选项，确保预防性维护操作，
为您的补偿单元提供监督和安全性。
应用
1或3个变压器的连接使Master控制Var成为安装中的理想控制器，允许以下内容：
- 在以下情况下从1变为3变压器：
- 无功能量惩罚的变化
- 消费习惯的变化
- 系统中存在重大不平衡
- 更换任何电容器组的控制器
- 适用于4个物镜cosφ的安装，因为它可以适应补偿需求（不同的时间段）。
- 它可以与中压补偿单元一起使用。
Reactive energy controller MASTER control Var
Description
Measurement with three current transformers guarantees an analogue reading of the company’s meter. The Master control Var reactive energy controller is the controller 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.
Master control Var is a controller 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.
Application
The connection of 1 or 3 transformers makes Master control Var the perfect controller in
any installation, allowing the following:
- Changing from 1 to 3 transformers in the following cases:
- Changes in reactive energy penalties
- Changes in consumption habits
- Significant imbalances in the system
- Replacing the controller of any capacitor bank
- Perfect for installations with up to 4 objective cosφ, since it can adapt to any
compensation need (different time periods). - It can be used with Medium Voltage compensation units.
