JN-LDQH-60112 TRACKING TEST APPARATUS
Tracking Test Apparatus IEC60112 (600V)
TRACKING TEST APPARATUS indicates the relative resistance of solid insulating electric materials when submitted up to 600v. This method exposes the tested object to electric stress under water action with contaminant addition(nh4ci)tracking may occur during test when voltage is activated on a defined disposition of electrodes on the material surface and electrolyte drops(nh4ci)are injected during a definite interval of time. The number of necessary drops to cause damage on the material increases with the reduction of the applied voltage. Under a critical value, tracking does not occur.
Tracking: Progressive formation of conductive tracks produced on the surface of an insulating solid material, due to the combination of electric stress effects and the electrolyte contamination on the surface.
JN-LDQH-60112 TRACKING TEST APPARATUS meets all the IEC standard requirements(International Electrotechnical Commission)
