• Backfeed: A device has been detected to have real power flow in the reverse direction.

• Under Voltage: A device's voltage is at the low end of permissible operation

• Over Voltage: A device's voltage is at the high end of permissible operation

• Switch Overload: The current flowing through a switch is close to (or exceeding) rated value

• DistTrans Overload: The power flowing through a distribution transformer is close to (or exceeding) rated value

• Feeder Capacity: The current flowing through a Feeder Head Breaker is close to (or exceeding) rated value

• Conductor Overload: The current flowing through a conductor is close to (or exceeding) rated value.

• Unprotected Ground Violation: The device is not adequately protected from ground faults by the upstream protective device.

• Ground Reach Violation: The protective device does not provide adequate protection for ground faults on at least one downstream device.

• Unprotected Phase Violation: The device is not adequately protected from phase/line faults by the upstream protective device.

• Ground Phase Violation: The protective device does not provide adequate protection for phase/line faults on at least one downstream device.

• PowerTrans Overload: The current flowing through a Substation Transformer is close to (or exceeding) rated value.

• DistGen Time-to-Live (TTL): The distributed generator time to live is expected to expire (or has already expired) indicating the unit is close to running out of fuel/charge or already has.

• DistGen Overload: The distributed generator sustaining a section of the network in island mode is overloaded.

• Model Error: A device is determined to have invalid data attributes prior to attempting power flow solutions

• Inconclusive: The power flow engine could not converge on a solution. The solution details may give more information about the failures.

• Inconclusive SCADA: The feeder is an electrical island that contains a suspect SCADA related feeder. This means there is some question about the integrity of the results island-wide.

• Suspect SCADA: The data from SCADA can't be matched to a power flow solution. This could mean that a device in the field has changed state and the NMS is unaware. There could be modeling or SCADA issues.

• Solution Failed: The power flow engine diverged from a stable solution. This indicates a problem with the electrical model, for example an incorrect attribute or connection on a service. The solution details will give more information about the failures and identify the area where the problem occurs.

• Inconclusive Solution: The power flow engine could not converge on a stable solution. That is, after the configurable number of iterations had been reached, the engine was still finding significant discrepancies. This indicates a problem with the electrical model, for example an incorrect attribute or connection on a service. The solution details will give more information about the failures, and identify the area where the problem occurs.

• Neutral Current Overload: The current flowing through a neutral conductor is close to (or exceeding) rated value.

• Voltage Angle Violation: The difference in phase angles on the two sides of the open switch exceeds the configured limit.
