“…The implementation of this technique and its repeatability have been recently focused in many efforts. Reference [38]- [42] indicated that the measured resistance in this test is dependent on the injected DC current and opening velocity. The resistance decreases with an increase in the injectedcurrent and decrease of the velocity.…”

“…DRM could provide valuable evidence on the condition of the main and arc contacts. However, the main weak point of this approach is infeasibility in real-time assessment [42] [55]- [57]. Consequently, an online condition assessment method will be required to evaluate the status of the contacts encapsulated in an insulation medium.…”

“…identification of the thresholds of the healthy and faulty cases to prepare an intelligent fault prediction approach. In this regard, a regression method has been developed to predict the degradation of the contacts in HVCBs in [42]. While in [18], SVM and neural network have been employed to identify the healthy and faulty domain of diagnostic features, reference [21] presented a probabilistic approach using clustering and data mining to intelligently discriminate between faulty and healthy diagnostic features.…”

High voltage circuit breakers (HVCBs) play a critical role on providing the desired reliability, and resiliency in power systems. In order to extend their lifetime and predict the failures, various maintenance policies could be applied on these critical components. Amongst these strategies, condition-based maintenance (CBM) provides a satisfactory agreement with future smart environment. This paper aims to provide an insight into the relevant developments in this subject and to explore the viable visions compatible with future research stream. Accordingly, three directions, i.e. diagnostic signals, intelligent modelling and using monitoring data in asset management have been addressed in this paper. It presents challenges dealing with real-time assessment of the diagnostic signals relating to measurements, and analyses. Subsequently, the issues associated with using artificial intelligent (AI) and Machine learning for providing intelligent algorithms have been discussed. Finally, the connection between the monitoring data and the asset management approach is investigated. The latter is looking for the subjects including remaining lifetime estimation, prioritization, and health index definitions. This paper has attempted to make a bridge from past to future research trends in the failure diagnosis of HVCBs.

“…Perform DRM tests at low contact speed. The lower the contact speed, the more repeatable the dynamic contact resistance curves are [5,6,9,13]. When the DC injected current (I d ) is 100 A, the contact speed should be 0.002-0.2 m/s, which is lower than the rated speed of the tested circuit breaker [5,9]; when I d is up to 1300 A, the influence of the contact speed on DRM test results can be ignored [6].…”

“…In other words, this method does not take the friction heat in DRM tests into consideration. Liu et al [13] measured the effective contact area of the contact finger by the laser scanning microscope, and it found that the current rise made the effective contact area bigger and led to the decrease of the resistance. However, it did not explain how the current rise made the effective contact area bigger, and it did not put forward a determination method for the amplitude of I d .…”

The fault of power circuit breaker (PCB) can lead very serious problems, especially in high voltage-power grid. The structure of contacts may be composed of main contacts and arc contacts, and this structure can avoid ablation of main contacts efficiently. It is necessary to study the eroded state of the arc contacts and the dynamic contact resistance of arc contacts to estimate the operating state of the PCB. The wear of contacts contains arc ablation and mechanical wear through the characteristics of contacts. The arc ablation is caused by the high temperature of the arc and the mechanical wear is caused by the mechanical friction of static and movable contacts. Some experiments have been done under different size of contacts and different current through them. The results show that the mechanical wear increases, sometimes heavier, with the increase of the size of fixed contacts and the decrease of the size of movable ones because the force between fixed and movable contacts becomes larger. The results also show that the ablation of arc contacts increases with the increase of current, especially when the current is up to 20 kA. With the high temperature of arc reaching the hardness point of copper, the arc ablation and mechanical erosion are increasing obviously since the contacts become soft and easy to wear. Another result of the study shows it is important to choose the material of contacts and the force between movable and fixed contacts. The harder and less resistance the material of contacts, the better the operating situation. To monitor the operating situation of the breaker, the dynamic contact resistance was measured 25 times. As a result, the dynamic contact resistance is sensitive to the current and increasing with the increase of continuous experiment time because of the increasing of metal ions. Furthermore, if the SF 6 in the PCB is changes, the dynamic contact resistance would be changed. The dynamic contact resistance in this experiment varies substantially within the range of 80-250 μΩ at the current of 20 kA.
