Spark tester - power frequency quality inspection report template
3.2.1 test electrode at the bottom of the shape of "U" shape, electrode length 600 ㎜, effective width not less than (80 + 30 ㎜)
3.2.2 the bead chain contact electrode was chain grew up in depth at the bottom of the "U" shape
Beads diameter 2.5 ㎜, the spacing between two chains should be no more than five ㎜
Beads diameter 5.0 ㎜, the spacing between two chains shall not exceed 8 ㎜
Two adjacent in a string of beads spacing should be not more than 2.5 ㎜
Bead chain shall be of uniform distribution, the surface is smooth, the sample (s) should not be cut by any burrs, bead around each section should be flexible.
3.3 breakdown counter can accurately record the spark breakdown.
3.4 the sensitivity test
Test high voltage electrode and ground connection between the artificial fault device inspection, spark machine is breakdown.
