我们在电子电压调节领域和监控领域分别有着超过40年和10年的深耕，得以不断改进和完善我们的监控系统。
我们的监控解决方案可对变压器及其组件最重要的运行状态进行测量和计算。这使它们得以满足所有现行标准。传感器可以通过数字输入或模拟输入进行连接。运行状态在浏览器中进行本地显示，并可通过常规的控制系统协议发送到控制室。这是监控设备运行状态的不二之选。用户还可选择将自动化任务（如冷却系统控制，自动电压调节）添加到我们的监控系统中。得益于ISM®直观控制界面（IICI），可以通过直观的图形界面快捷方便地进行现场调试。
ETOS®系列对MR有载分接开关进行监控。我们借助40年的专业知识来开发这项技术。除了分接开关，ETOS®还可监控变压器及其所有组件。这些系统采用模块化设计，允许根据对电力变压器进行监控和控制的各类需求进行配置。
