In this paper a new approach to the analysis of test results for circuit breakers is discussed. It is implemented through new software called Automated Circuit Breaker Monitoring system ACBM. The circuit breaker performance is evaluated based on the analysis of Digital Fault Recorder (DFR) recordings taken from circuit breaker control circuitry. This paper describes the testing procedure and us...

An approach of the worst case analysis of the analog electronic circuits based on the circuit description in parameter space is proposed. A DC, AC or transient worst-case analysis can be performed only testing the circuit for the vertices of a polytope in conjunction with a circuit simulator or computational environment. In order to validate and show the effectiveness of this approach, DC worst...

The impact on circuit performance of parameters uncertainties can be effectively evaluated by describing the resulting stochastic problem in terms of orthogonal polynomial expansions of electrical quantities. This contribution formalizes a rule for the construction of an augmented instance of the original circuit, that provides a systematic solution for the unknown coefficients of the expanded ...

Calculation of the design parameters current transformers (CTs) is very complex due to their magnetic and thermal properties, complexity structure, different ferromagnetic properties materials nonlinearity B-H curve core material. The secondary output these used for both measurement protection circuits. Therefore, AT's accuracy must be good precise. In this study, transformer modeled as 2D usin...

extended interaction oscillators (eio) are vacuum electronic sources of microwave, millimeter-wave and terahertz radiations. in this paper, eio is investigated by using a circuit model. the value of the coupling element in the model is evaluated from the near band-edge dispersion characteristics of the rf structure. the end external loading of the interaction structure is equivalently modeled b...

This paper presents the design, construction and testing of a new capacitive tactile sensor for measurement of normal tactile force. The operation of proposed sensor has been investigated in ASTABLE and MONOSTABLE circuits. According to the results of these circuits the deviation of ASTABLE circuit results is less than MONOSTABLE circuit results. In addition, the results obtained from ASTABLE c...

A software organization of a new circuit simulator, SAMOC (Switchedcapacitor Analysis of MOs Circuit) is presented in this paper. SAMOC employs extremely simplified, piecewise linear, resistive models to represent the semiconductor devices such as MOS transistors and ideal diodes in the simulated circuits. SAMOC also supports ideal switches and ideal capacitors for analyzing switched-capacitor ...

In this paper a new synthesis for circuit design of Euclidean distance calculation is presented. The circuit is implemented based on a simple two-quadrant squarer/divider block. The circuit that employs floating gate MOS (FG-MOS) transistors operating in weak inversion region, features low circuit complexity, low power (<20uW), low supply voltage (0.5V), two quadrant input current, wide dyn...

We have developed representations and analysis methods for electrical circuits in a deductive system called DUCK.** Circuits are represented as conjunctions of logical predicates. Circuit analysis is done as an iteration of proofs which determine the basic structures in the circuit. Electrical constraints for the circuit are produced from the results of the proofs. The constraints are then solv...

When test vectors are applied to a circuit, the fault coverage increases. The rate of increase, however, could be circuit-dependent. In fact, the actual rise of fault coverage depends on the characteristics of vectors, as well as, on the circuit. The paper shows that the average fault coverage can be computed kom circuit testability. A relationship between fault coverage and circuit testability...
