The V-CCT indices indicate the severity of fault-initiated contingencies by comprehensively evaluating transient voltage dips according to dynamic performance criteria.
The severity of faults is addressed through redundancy analysis.
Unlike most fault diagnosis techniques, the proposed solution detects, isolates, and identifies the severity of faults in the system within a single integrated framework.
The expert system, denominated PROMISE as the Italian acronym for PROgnostic and Intelligent Monitoring Expert System, generates, in real time and in a form directly useful to the plant manager, information on the existence and severity of faults, forecasts on the future time history of both detected and likely faults, and suggestions on how to control the problem.
Even under a short-circuit fault condition, an effective strategy can reduce the severity of the fault to some degree by controlling the fault current and voltage.
For bearing fault diagnosis by envelope analysis, the frequency of the bearing fault and several of its harmonics are required to assess the severity of the fault, because the number of harmonics in the envelope is directly related to information on the geometrics of the fault.
Automated systems can now monitor implant runs and flag possible out of control situations for review by process and equipment engineers, or depending on the severity of the fault, prevent further processing of material while the fault is investigated.
The obtained numerical results suggest that the proposed fault estimation method provides an estimate of the size and severity of the fault, which can be important in many civil engineering applications.
However, for a motor with a stator winding fault a circle is obtained, whose radius is related with the severity of the fault.
The proposed fault estimation method provides a direct estimate of the size and severity of the fault, which can be important in many civil engineering applications.
An index is proposed to assess the severity of the fault present in the motor.
