Energy logger
23 May 2018
The Tinytag Energy Logger from Gemini Data Loggers is a portable data recorder which monitors single and three phase power usage in premises with high consumption equipment. Recorded data can then be analysed to help understand how and where energy is used and to identify opportunities for reduction.
The Energy Logger uses non-invasive flexible coils to monitor the current in each phase of a three phase supply, while voltage information may be obtained via a standard 13A wall socket. Recorded data is downloaded to a PC – where it presented initially in graphs and tables in the easy to use Tinytag Explorer Software – to help identify times of peak load and to identify power hungry or inefficient equipment. The unit also records 'Power Factor' (PF) data, a measure of power transmission efficiency: this can be significant because power companies typically charge a higher rate for industrial or commercial customers with a low PF.
