Data Logging For Electrical Systems

A data logger (or sometimes called a "datalogger" or "logger") is a specialized electronic device that measures and records specific data over a certain period of time or in relation to its location either with a built-in instrument or sensor or via external instruments and sensors.

Common Uses for Data Logging

• Monitoring voltage and amperage for specified durations to confirm quality. 
• Monitoring voltage and amperage for specified durations to monitor for anomalies such as spikes and losses.
• Identifying 'ghost' issues that are reportedly intermittently present. 
• Providing proper reports that can be conveyed to authorities and power companies wherein power quality issues result in claims or damages to property and equipment. 

Typical Applications

• Data Logging equipment is connected at the ahead of the source affected load, monitored, reported and analyzed for various determinations.
• Typically, depending on the subsequent issue, the logger is left in place for 24-72 hours. 
• Under extreme cases, the logger is left in place or moved several times for 1-3 weeks until data reflects the pinpointed issue. 
• The data collected helps determine the proper treatment of troublesome anomalies and upon detection, usually results in the creation of a proper repair scope.
