Noninvasive imaging of circuit breakers under short-circuit testing is addressed by recording the magnetic field produced over an array of external sensors and by solving an inverse problem to identify the causing current distribution. The temporal and spatial resolution of the sensing chain are studied and implemented in a physical set-up. A wire model is adopted to describe electrical current distribution. Additionally, the simpler, more direct approach to evaluating the passage of electric current in front of sensors is proposed. The dynamics of suitable approximating models of the electric

The most basic transient a circuit breaker needs to suffer during its activity is the transient recovery voltage (TRV), started by the electric force system as a characteristic response on flow interference. To test high voltage CBs, direct testing utilizing the force system or short out alternators are not practical. The testing of high voltage Circuit Breakers (CBs) of bigger limit requires huge limit of testing station. An equal infusion of short out current and transient voltage to medium and high voltage circuit breaker (CB) by a synthetic model is examined. Transient recovery voltage is

Electrical energy transmission plays an important role as a means of distributing electrical energy from generation to distribution and consumers. During the process of distributing electrical energy, disturbances such as short circuits often occur. Therefore, there needs to be safeguards so that the distribution process runs well. One of the safety equipment in the main substation is the circuit breaker. Circuit breaker is a mechanical switch or switching equipment that can close, transmit or disconnect the load current under normal conditions or under abnormal conditions such as a short circ

This paper is devoted to the development of a model of an autonomous electric power system to study random processes of voltage, current and power changes in emergency and dynamic operation modes. A diagram for calculating short-circuit currents has been presented, which was focused on a typical wide range of autonomous power plants with three diesel generator units. A model of an autonomous power plant has been developed, allowing to solve the assignments of determining short-circuit currents and starting currents of electric power machines. The equivalent network of the studied power system

This article presents a computer vision-based approach to switching electric locomotive power supplies as the vehicle approaches a railway neutral section. Neutral sections are defined as a phase break in which the objective is to separate two single-phase traction supplies on an overhead railway supply line. This separation prevents flashovers due to high voltages caused by the locomotives shorting both electrical phases. The typical system of switching traction supplies automatically employs the use of electro-mechanical relays and induction magnets. In this paper, an image classification ap

With the growing demand of electric vehicles, design of circuit protection devices is now an important consideration in automobile industry. Modern day circuit protection devices have been constantly undergoing miniaturization due to requirement of minimizing the foot print for use in electrical vehicles and aerospace applications. This size reduction makes thermal management one of the most important aspects of their design. Use of numerical model to predict heat transfer can significantly reduce the cost and time required in testing physical prototypes. In this paper, three different approac

DC High Speed circuit-breakers (DC-HSCB’s) and Protective Relays (PR’s) are present in all sorts of rail infrastructure. National or urban railways, tramways or metro’s, they all rely on this equipment to protect them from disastrous situations. The circuit-breakers can be installed either on board of the trains or on the trackside, in traction power substations. Protection Relays are, in most cases, part of the fixed installation. Needless to say that the DC-HSCB and PR are critical parts of the rail infrastructure. In the best case a faulty unit can cause the trains to stand still, in the wo

Electron field emission is the process by which electrons tunnel from a cathode to an anode, usually through vacuum, by the application of a large voltage bias. Field-emission devices find applications in flat panel displays, electrical circuit breakers, and power diodes. A significant amount of heat can be transferred to the anode from high-energy electrons as they impact the anode surface. This study investigates the heating of a thin, disc-shaped steel anode by field-emitted electrons from a single carbon nanotube. Experiments have demonstrated a temperature rise of more than 11.0 C at the

This study evaluates the technical and environmental feasibility of mechanically recycling post-industrial bulk molding compound (BMC) waste from the manufacturing of low voltage circuit breakers. Testing reveals that incorporating up to 10% recycled BMC as filler substitute maintains the required mechanical and electrical properties. A life cycle assessment shows that while replacing virgin fillers with recycled BMC has limited effects on the carbon footprint of the material, the overall product system benefits significantly by avoiding waste incineration. Moreover, optimized scenarios like m
