Identifying energy savings

12 November 2018

The Tinytag energy logger from Gemini Data Loggers is a portable data recorder which monitors power usage in premises with high consumption equipment. It offers an effective means of checking power usage. It can monitor single and three phase power usage, and 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 in graphs and tables in Tinytag Explorer Software – to highlight 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 as power companies typically charge a higher rate for industrial or commercial customers with a low PF.
