Final Circuit Monitoring from ABB
The latest metering technology ABB’s CMS (circuit monitoring system) can now be integrated into ABB Protecta Plus distribution boards (pictured), as well as retrofitted into other manufacturers distribution equipment. It enables operators of commercial buildings such as shopping centres, offices, hotels and airports to access more accurate and reliable consumption data than ever before, with the ultimate goal of identifying ways to enhance energy efficiency, improve the billing of tenants and create detailed reports on energy consumption.
This is essential so that the building owner can demonstrate the fairness when allocating energy costs to building users.
Although many commercial properties were not originally designed for sub-metering, solutions such as ABB’s CMS system can monitor consumption by individual tenants in a building, such as retail outlets or boutiques, businesses in office blocks or different functions such as airline lounges or baggage handling at airports. Being compact, The CMS can be retrofitted wherever they are needed.
Operators of commercial properties must declare the energy performance of their buildings as part of the Government’s drive to reduce carbon emissions and increase the efficient use of energy. Energy declarations require building operators to account for different types of load separately, so it is important to have confidence in the consumption figures for lighting, elevators, heating and ventilation, etc.
Because of this, accurate sub-metering is extremely valuable as it gives building operators confidence when reporting their performance. As well as supporting the legal requirements for reporting, accurate metering highlights ways to increase the building efficiency as it helps them to identify potential energy savings.
Only with accurate sub-metering and analysis of consumption is it possible to maintain energy management standards such as ISO50001, L2 building regulations, BREEAM and others.
Another benefit of accurate metering is that measuring the average power during a set time interval confirms the maximum demand value. This knowledge enables electrical consultants to dimension a building’s electrical installation to best fit the building’s occupiers.
Some key features of the circuit monitoring system (CMS) is the ability to connect up to 96 metering points through a single control unit, that evaluates data picked up by the sensors and enables live monitoring via the in-built web server. The CMS also stores the logged data internally, this can be exported via CSV files and there is no ongoing licence fee for inbuilt energy management software. The control unit is compatible with protocols such as RS485, Modbus RTU and LAN (TCP/IP and Modbus TCP), so as well as keeping and viewing the data locally, the information can also be sent to an external energy management system if required.
