安全地运行变电站

控制电压

高可用性从可靠的供电开始

控制电压

为了电气安全,必须监视控制电压回路。毕竟,未检测到的电气故障与未预料到的系统停机同样重要并且也大大增加了火灾风险。同时,不在计划中的服务干预很可能是昂贵且耗时的。一些变电站的保险公司同样也要求有效的状态监视系统。本德尔的状态监视系统能够使您对系统的所有相关数据一目了然。

不间断电源

安全的电源直到发电机运行

UPS

不间断电源 (UPS) 用于确保在电源出现问题时提供重要的电力负荷的电源。UPS系统 (普通电池或摆锤系统) 在此阶段桥接直到激活应急电力系统 (发电机) 或者系统能够再次使用。本德尔产品能够连续不断地监视并且确保电气安全。

电压监视

三相交流电压的监视

电压监视

VMD258模拟电压监视仪监视三相交流系统的欠电压和过电压 (窗口功能)。它不需要中性点连接,因此适用于所有的三相交流系统。使用被监视系统的电压为设备的供电。电子设备、继电器和连接外部电能存储单元的电源的与双重绝缘系统隔离。特殊输入变压器阻止系统中干扰因素的转移。欠电压和过电压的响应值和响应延迟可以被调整到任意水平。
