Electrode material
|
Using the upper and lower electrodes, an alternating voltage of 2.5 kV to 10 kV was applied.
When the short circuit leakage current is equal to or greater than 60mA in the test circuit, the time is maintained for 2 seconds.
Relay action, cut off the current, indicating that the sample failed
|
|
Dropping device
|
The time constant of the drip device is adjustable so that the drip volume and the drip time interval are precisely controlled
|
|
Test voltage current
|
500 ~ 10kV (adjustable) (digital display); 5 ~ 60mA (binning can be set), short-circuit current up to 100mA; (digital display);
|
|
Current control impedance
|
60, 50, 30, 15KΩ or set according to actual requirements, achieve the requirements of secondary test current 10, 22, 33 and 40mA by switching
|
|
Secondary current limiting resistor
|
15KΩ or set according to actual circuit requirements
|
|
Test electrode

2 pairs, respectively, are smooth burrless stainless steel electrodes 0.15mm thick, 12.7×25.4, angle of 160°;
And tungsten rod electrode Φ2.4 × 45mm, with the axis and the angle of 30 ° head;
|
|
The force of the electrode on the sample
|
50g±5g.
|
|
Number of droplets
|
1-9999 (digital display, can be preset)
|
|
Test wind speed
|
0.2m/s (new standard)
|
|
Pressure drop
|
1.0A 0.1A (error); 100mA (correct) ±8%
|
|
Tracking judgment
|
Criterion A: When the current through the sample in the high pressure loop exceeds 60 mA, it reaches the end point.
The overcurrent device shuts off the power at this time.
Criterion B: When the mark reaches the mark on the surface of the sample at 25 mm from the lower electrode, the end point is reached.
