  • Dielectric Gases | Electrical4U

    Breakdown in GasesBreakdown MechanismProperties of Dielectric GasesApplication of Dielectric GasesActually, it is the fall in resistance of the insulating gases. This will happen when the applied voltage increases than the breakdown voltage (dielectric strength). As a result of this, the gas will begin to conduct. That is, there will be a strong voltage rise in a small area in the gas. This area of strong voltage rise is the reason of partial ionisation of nearby gas and starts conduction. This is made intentionally in low pressure discharges (in an electrostatic precipitator or in fluorescent lights). The Paschen’s law approximated the voltage which causes electrical breakdown (V = f(pd)). It is actually an equation which explains the breakdown voltage as the function of product of pressure and gap length. In that a curve is obtained, this is called Paschen’s curve. The Paschen’s curve for air and argon is represented in figure 1. Here, as pressure is decreased, the breakdown voltage also reduced and then gradually increases which exceeds the original value. At standard pressur...
