Monitoring of abnormal events in a distribution feeder by using a single technique is a challenging task. A number of abnormal events can cause unsafe operation, including a high impedance fault (HIF), a partial breakdown to a cable insulation, and a circuit breaker (CB) malfunction due to capacitor bank de-energization. These abnormal events are not detectable by conventional protection schemes. In this paper, a new technique to identify distribution feeder events is proposed based on the complex Morlet wavelet (CMW) and on a decision tree (DT) classifier. First, the event is detected using CMW. Subsequently, a DT using event signatures classifies the event as normal operation, continuous and non-continuous arcing events (C.A.E. and N.C.A.E.). Additional information from the supervisory control and data acquisition (SCADA) can be used to precisely identify the event. The proposed method is meticulously tested on the IEEE 13-and IEEE 34-bus systems and has shown to correctly classify those events. Furthermore, the proposed method is capable of detecting very high impedance incipient faults (IFs) and CB restrikes at the substation level with relatively short detection time. The proposed method uses only current measurements at a low sampling rate of 1440 Hz yielding an improvement of existing methods that require much higher sampling rates.

“…Moreover, the arc extinguishing stage was modeled using a series connection of the Cassie and Mayr arc models [26]. The Cassie model describes the arc during high currents while Mayr model describes the arc at low current near the zero crossing [24]. The CB parameters for the test feeders were set as shown in Table 2.…”

The static and dynamic voltage distribution characteristics and voltage sharing design of a 126-kV modular triple-break vacuum circuit breaker (VCB) was discussed in this paper. The finite-element method and power frequency tests were used to calculate and verify the static voltage distribution ratios and distributed capacitance parameters of multi-break VCBs, respectively. A model combining the post arc current model and equivalent capacitance model was proposed for simulations of dynamic transient recovery voltage (TRV) distribution characteristics of the triple-break VCB. The simulation results indicated that besides the stray capacitances, the TRV sharing design should take the influence of residual charge (RC) into account, and the influence of RC on the TRV distribution is relevant to the differences of RC parameters among the series interrupters. Therefore, the appropriate value of grading capacitors should meet the requirement of the worst case. Based on the investigation of this paper, a 126 kV U-shaped triple-break VCB prototype with 1000 pF grading capacitors has been produced, and the successful large current breaking tests indicate the good breaking capacity and suitable voltage sharing design of the triple-break VCB.Index Terms-Distributed capacitance, finite-element method (FEM), grading capacitor, post arc current (PAC), residual charge (RC), transient recovery voltage (TRV), vacuum circuit breaker (VCB), voltage distribution. 0093-3813

“…From the moment that Mayr and Cassie introduced their differential equation for describing the dynamic arc behavior 15–17 a lot has been published about the application of arc models and even more publications are devoted to modifying arc models and breakers modeling such as Refs. 18–24. In simulation of breaker during short circuit breaking test an arc model will be used instead of breaker in simulated circuit.…”

ABSTRACT:This article describes an efficient method of teaching short circuit breaking test of high-voltage circuit breakers, to undergraduate students of power system groups in electrical engineering departments, as a part of a high-voltage course for senior undergraduate students. The article shows how to simulate the components of testing circuit and breaker in order to teach students the test. Evaluation of the simulation over several semesters with more than 40 students is very positive in terms of their developing confidence in and understanding of short circuit breaking test on high-voltage circuit breakers.
