How is the voltage distributed when GDT and MOV are used in series?
Jun 25 , 2025
Without lightning surge voltage, that is, under normal power frequency voltage, the voltage distribution of MOV (metal oxide varistor) and GDT (ceramic gas discharge tube) is mainly affected by their electrical characteristics. 1. GDT (Ceramic Gas Discharge Tube): GDT has extremely high parallel impedance (about 1TΩ) and extremely small parallel capacitance (below 1pF) unde...
