Description
• Display instantaneous stator leakage current on each phase of the motor.
• Display compensated dissipation factor and change in dissipation factor from a given reference point.
• Display motor stator temperature and average temperature.
• Display line voltage and frequency data values.
• Retrieve historic data stored on board the monitor for data analysis.
• Set alarm levels for annunciation.
• Configure the temperature range and time period for learn and extend modes for temperature learning, and view the current learning state.
• View the number of temperature samples, vs. operating temperatures, that builds the learning curve used for temperature compensation.
