The Tinytag Energy Logger is a portable, non-invasive solution for monitoring single and three-phase power supplies in commercial and industrial settings. Designed for simplicity, the unit features a self-configuring setup—once the flexible Rogowski coils are clipped around conductors and the voltage lead is connected, the logger automatically detects the wiring configuration and begins displaying real-time values. It is an essential tool for energy managers looking to troubleshoot equipment, meet ISO 14001 targets, or perform “before and after” efficiency audits. Unlike standard loggers, it includes an on-device display for spot checks and a “Record” button to start logging sessions without needing a PC on-site.
To accommodate different cable sizes and tight distribution boards, the system utilises flexible Rogowski coils (all rated up to 2,000A AC RMS) available in three distinct internal loop diameters:
Large Coil (175mm diameter): Supplied with the TGE-0002 Kit. Designed specifically for thick, heavy-duty busbars or heavy trunking feeds found in primary substation or whole-facility monitoring.
The Tinytag Energy logger is supplied in a carry case with three current coils, UK and EU mains leads, a USB cable, a copy of the Tinytag Explorer software and a user manual.
Please note: the Tinytag Energy Logger is only for sale in the EU and Australia.
