How to solve the problem set drive repair harmonic problem? Diode rectifier circuit will ...... ...... 5,7,11,13 third harmonics of. Impact: current increases, the power factor drops Solution: Please install the ac or dc reactor (3% drop so) drive repair what is "varistor" "varistor is a noun in mainland China, meaning 'in within a certain range of the resistance value of current and voltage with the voltage change '140 module repair, or is that' the resistance value of the voltage sensitive 'of resistor corresponding English name is "Voltage Dependent Resistor" abbreviated as "VDR". Varistor The resistive material is a semiconductor module maintenance, so it is a variety of semiconductor resistors. 'zinc oxide' (ZnO) is now widely used in varistors OMRON module maintenance, its main material divalent element (Zn) and hexavalent elemental oxygen (O) of the composition. Therefore, from the perspective of the material point of view Omron module maintenance, zinc oxide varistor is a "Ⅱ-Ⅵ family-oxide semiconductor." In China Taiwan, varistor is based named after its use, called 'surge absorber' varistor according to their use is sometimes also referred to as "electric shocks (surge) suppressor (absorber)" siemens module maintenance |..
