This paper introduces a novel non-integral method for calculating AC capacitor voltage in shunt hybrid active power filters (SHAPFs). These commonly use passive (PPFs) that can introduce containing harmonics into the capacitor, leading to overvoltage situations be dangerous. To avoid accidents due overvoltage, it is necessary monitor continuously. The proposed enables calculation of across usin...

Abstract Arrester is used to protect various electrical equipment in the power system from lightning overvoltage, working frequency transient overvoltage impact and damage. Zinc oxide arrester widely system. Creepage distance a necessary item of performance test. It project for factory testing centralized network access testing. At present, measurement creepage mainly adopts artificial method p...

A first-principles-based charge-discharge model was developed to simulate the capacity fade of Li-ion batteries. The model is based on the loss of active lithium ions due to solvent reduction reaction and on the rise of the anode film resistance. The effect of parameters such as exchange current density, depth of discharge ~DOD!, end of charge voltage, film resistance, and the overvoltage of pa...

Modern power converters frequently require snubberless operation of p-i-n diodes [1]. Due to the presence of fast-switching components, like last-generation GTOs and IGBTs, the diodes must be able to withstand, at turn-off, quick inductive switching, i.e., large, negative time derivatives of the diode current ((dID/dt)1<0) without large overvoltages, which requires a limited time derivative ((d...

A silicon photomultiplier (SiPM fabricated and characterized. The SiPM was (Separation of Absorption, Charge and Multipl which was optimized for blue light detection positron emission tomography (PET). The achieved high geometric fill factor of 64% and a low brea about 22V, while the temperature dependence of b is only 17mV/°C. The gain and photon detection device achieved were also measured un...

Ferroresonance is a special case of disturbance that involves high levels of overvoltage and overcurrents distortion. This phenomenon can severely affect voltage transformers and its consequences can be catastrophic. This paper analyses different practical solutions against ferroresonance phenomenon in voltage transformers, highlighting the current development of ferroresonance detection techni...

The computation program of the transient recovery voltages that appears across the terminals of a circuit breaker, after the low inductive current has been interrupted at the disconnecting no load high voltage transformers, using the routines set developed in Matlab is presented. The computation algorithm is based on the peculiarities of operation of the transformer. The computation program has...

Power quality and power disturbances have become an important increasing factor throughout electrical networks. Ferroresonance is one of these disturbances that can occur on distribution systems, causing quality and security problems. This paper analyzes the ferroresonance as a nonlinear resonance phenomenon of erratic nature and difficult prediction. The theoretical principles of this phenomen...
