The DOW3000 is a configurable high-voltage test system that can be extended for slow and fast damped oscillatory waves, impulse voltage test, or any combination.
The breakdown voltage of [SF.sub.6]-C[O.sub.2] mixtures is higher than that of pure [SF.sub.6] at some pressures for impulse voltages. As an example at above the pressure of 3 bar, the strengths of 1% [SF.sub.6]-C[O.sub.2] mixtures are slightly higher than those of pure C[O.sub.2] at negative impulse voltage [10].
This overvoltage category involves equipment with withstands impulse voltage level of 1.5kV and it is the most rigorous requirement for the protection effect of SPD.
On the other hand, low impedance might lead to under-damping, significant reduction of peak impulse voltage and oscillations, as in the case of [Z.suv.antenna] = 5 [ohm].
According to the criterion, for impulse voltage of any waveshape a flashover will occur only if particular value of area A is reached (Fig.
Impulse voltage is rated at 3.5kV and operating current up to 34A for wire size 4.0mm2.
The present paper deals with analysis of neutral current obtained after applying a standard impulse voltage waveform represented as
The screw cage contact technology accepts wire sizes 12 AWG to 22 AWG, is 5 mm wide, has a 500V rated voltage, 6 kV rated impulse voltage and mounts to a TS-35 DIN rail.
It has a UL 94-VO flammability rating with 500V rated voltage and 6kV rated impulse voltage. The screw cage contact accepts wire sizes 12-22 AWG.
Units can withstand an impulse voltage in excess of 8 kV Also, users can change the unit's batteries with a standard screwdriver without breaking the calibration seal.
