“The days of electricity flowing through cables unobserved are numbered. With digitalization, it will be possible in the future to not only fully monitor electricity, but also to control it flexibly and use it much more efficiently. We already provide the basis for this with our technologies,” said Andreas Matthé, CEO of Low Voltage Products, Siemens Smart Infrastructure.
Digitalization of electrical installations
With the new 5SL6 miniature circuit breakers (MCB) and 5SV6 arc fault detection devices (AFDD) from the Sentron portfolio, Siemens brings digitalization to electrical installations. The compact devices combine overload, short circuit and arc fault protection with integrated communication and measuring functions in just one modular width (MW). They can measure electrical values such as current and voltage, as well as temperature and switching states for individual circuits and automatically identify error causes. Operators and electrical installers can quickly recognize loads with increased power consumption, as well as anomalies and disruptions in the electrical installation and intervene early on. All the data can be visualized on a PC, tablet or smartphone and connected to analytics tools and digital environments through the new 7KN Powercenter 1000 gateway.
Integrated building and energy management
The updated Sentron “powermanager” power monitoring software consolidates building and energy management in one single platform. Version 4.x can be used as a stand-alone software or, for the first time, integrated into the Siemens Desigo CC building management system as an expansion module. This allows all energy distribution and building automation systems to be operated, monitored and managed from a single system. Sentron “powermanager” analyzes electrical parameters such as voltage, currents and power quality. Especially, small and medium-sized businesses benefit from the easy-to-use software. They can easily identify potential savings or system errors, reduce energy costs and cut CO2 emissions. All analyses can be shown in flexibly configurable dashboards or report templates and assigned to cost centers. Users are automatically notified by e-mail or text messages (SMS) of irregularities in energy consumption or unusual system behavior.
In addition, integration in Desigo CC enables regression analyses. By comparing consumption data with information from presence detectors, for example, it can be determined if energy for lighting, heating or air conditioning is being used in temporarily unoccupied parts of the building. If electrical systems such as elevators or escalators consume an unusually large amount of electricity, this can be similarly compared with the maintenance intervals defined in the building management. If necessary, these must be shortened to avoid expensive repairs and breakdowns.
Real-time energy data analysis via app
The new Sentron “powermind” app analyzes energy data directly in MindSphere, the cloud-based, open IoT operating system from Siemens. Users see a real-time overview of current energy consumption and trends over time – both for entire systems as well as individual electrical loads. The app is easy to use and requires no specific IT skills, allowing even inexperienced users to enter the world of digital energy management.
