PC-based Power Monitoring System

Power monitoring system with the SENTRON product family

Components of the PC-based power monitoring system

The SENTRON product family offers the user a power monitoring software in the form of powermanager, and the corresponding hardware in the form of 7KT/7KM PAC measuring devices and 3WL/3VL/3VA circuit breakers, for implementing a complete power monitoring system.

The power monitoring system is approved by the German Technical Inspectorate and consists of the 7KT/7KM PAC measuring devices, the 3WL/3VL circuit breakers and the powermanager power monitoring software. It forms the technical basis for supporting an operational power management system compliant with ISO 500001.

The hardware and software components are optimally coordinated with one another. For example, special drivers for the SENTRON devices are integrated into the powermanager power monitoring software. These enable data to be acquired with minimal configuration effort and they display the key measured values or the status by means of predefined views.

This reduces the engineering costs. The device functions are given optimum support in the software.

• Status display of devices

The basic license of the power monitoring software offers the following basic functionality:

• Collection of measured quantities from the devices
• Presentation of the measured quantities in predefined standard views for the 7KT PAC1500, 7KM PAC3100, 7KM PAC3200, 7KM PAC4200 measuring devices and 3WL/3VL circuit breakers
• Free presentation of measured quantities possible, including those from non-Siemens measuring devices, using generic Modbus drivers
• Archiving of measured quantities
• Monitoring of status and limits, with generation of corresponding signals
• Load curve display for visualizing the archived data and online data
• Cost center reports based on predefined tariffs and archived consumption data
• OPC server
• User administration
• Load monitoring for complying with power limits
• Virtual computation

System configuration

• Integration of measuring devices by means of predefined device templates for the 7KT/7KM PAC measuring devices and the 3WL/3VL circuit breakers
• Easy integration of already existing modbus-enabled measuring devices
• Communication through Standard Ethernet
• Integration of devices with RS 485 interface (ModbusRTU) through Modbus gateway, e.g. the 7KM PAC4200 measuring device can be used as the gateway

Industries

The energy efficiency that can be achieved with consistent power monitoring and the derived optimization measures is crucial for all industries, e. g. the manufacturing industry, in non-residential buildings, in the field of services, and in infrastructure projects. This has a particular impact on competitiveness, particularly in view of rising energy prices.
