Energy Electricity monitoring system based on NI hardware TBG Solutions has developed a PC-based testing and measurement control system, based on National Instruments hardware, which can be used to monitor and record power usage under a Climate Change Levy Agreement CCLA). Powerlog helps heavy power users to keep their processes and monitoring procedures within the terms of the CCLAs, and make significant savings in energy costs. Thanks to work carried out for a large US owned printing group, TBG has adapted the system to run over an Ethernet network, with results accessible via a company intranet.
