Definitions

  • the invention relates generally to faulted circuit indicators and more particularly to the communication of the state of a transmission line by the faulted circuit indicator, including real-time or near real-time measurements of electrical current and voltage, as well as other state information.
  • FCls Faulted circuit indicators
  • FCls are used in the fseld of electric power distribution systems.
  • FCls are electrically connected to transmission lines in a power distribution system at various locations throughout the system, often in close proximity to system loads.
  • FCls between the fault and the .source will detect that a fault has occurred.
  • FCls that have detected a fault then display an indication that the fault has been detected.
  • a technician can then identify a fault by locating the transmission line between an FCl that indicates it has detected a fault and an FCl that displays no such indication.
  • conventional FCls Because of their binary nature, conventional FCls provide little assistance in locating a transient or intermittent fault.
  • FCls are reset either by a manual trigger, wherein a technician manually manipulates the FCl to remove the fault indication, or by a current trigger, wherein if the FCl determines that conditions on the transmission line have returned to normal, the FCl automatically resets.
  • an automatic reset is a desirable feature because it ensures that the FCl only indicates existing faults, which reduces the likelihood that a false fault indication will increase the amount of rime necessary for a technician to diagnose and repair an actual fault.
  • an automatic reset results in an intermittent or transient fault triggering an FCPs indicator only tor a short time, followed by an immediate reset of the indicator, making the location of a faulted FCl during the presence of a faulted condition nearly impossible.
  • conventional FCls cannot monitor other conditions on a transmission line that can pose risks to the life or performance of the transmission line and other related equipment. For example, power surges at certain levels can not be sufficient to result in a fault condition indicated by conventional FCls. However, such power surges can shorten the life of a transmission line that experiences those surges and any transformers or other equipment attached to that line. Additionally, conditions such as excess heat or vibration on a line can indicate a problem on a transmission line that, with the use of conventional FCls, cannot be detected until a fault occurs, potentially resulting in a loss of service for customers that might have been avoided had the condition been diagnosed earlier.

Abstract

L'invention concerne un appareil indicateur de circuit défectueux présentant une fonction de communication (FCI) et sa méthode d'utilisation. Un capteur est conçu pour recueillir des données concernant l'état d'un conducteur électrique. Un contrôleur relié de manière logique à un capteur à puce est conçu pour recevoir les données recueillies par le capteur et pour déterminer si il faut communiquer les données recueillies à un emplacement éloigné du FCI. Une installation de communication reliée de manière logique au contrôleur est conçue pour communiquer les données à l'emplacement éloigné en réaction à la décision du contrôleur de communiquer les données à l'emplacement éloigné. L'installation de communication peut comprendre un dispositif de communication cellulaire. L'emplacement éloigné peut comprendre un dispositif de communication cellulaire. L'emplacement éloigné peut également comprendre un système informatique destiné à recevoir des communications provenant du FCI.
