Chapter 1 PowerMonitor W250 Unit Overview
PowerMonitor W250 Data Overview
The PowerMonitor W250 unit sends data to the wireless receiver periodically.
The meter data is split into three sections:
• Cumulative Energy Consumption Metering Data: The power monitor
transmits accumulated real, reactive, and apparent energy, per-phase and
total, once per minute. The transmission is accompanied with the time
stamp of the most recent reading.
• Interval Metering Data: The power monitor sends, at the end of the user-
selected interval, a time-stamped record of the following data: real,
reactive, and apparent energy per phase and sum; minimum voltage per
phase and maximum current per phase during recording interval;
frequency.
• Node Identification, Configuration, and Status: Node configuration and
version; recording interval time setup, command and status word.
