Energy Harvesting METSyS Current Datalogger
The Energy Harvesting METSyS Current Datalogger is a 3 phase or optionally a 4 phase current datalogger. The small flexible Rogowski coil current sensors allow for quick and easy connection to circuits to be monitored whilst its internal rechargeable battery allows for 72 hours of logging on a single charge making it ideal for short term connected load studies such as compliance with NFPA’s National Electrical Code (NEC) 2014 Article 220.87 and meeting the requirements for uniform load calculations in accordance with the requirements of the California Electrical Code (CEC).
For applications where longer term measurements are required the battery life can be extended indefinitely by simply clamping the energy harvesting CT around one of the phases being measured eliminating the need for connection to a power socket.
