Comparative And Proof Tracking Indices Test Apparatus CTI And PTI With 0-600V Voltage
Standard:
IEC60112-2009 Method for the determination of the proof and the comparative tracking indices of solid insulating materials.
Application:
It is used to test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. Flammability Testing Equipment
Principle:
The upper surface of the test specimen is supported in an approximately horizontal plane and subjected to an electrical stress via two electrodes. The surface between the electrodes is subjected to a succession of drops of electrolyte either until the over-current device operates, or until a persistent flame occurs, or until the test period has elapsed.
The individual tests are of short duration (less than 1 h) with up to 50 or 100 drops of about 20 mg of electrolyte falling at 30 s intervals between platinum electrodes, 4 mm apart on the test specimen surface.
An a.c. voltage between 1 00 V and 600 V is applied to the electrodes during the test.
During the test, specimens may also erode or soften, thereby allowing the electrodes to penetrate them. The formation of a hole through the test specimen during a test is to be reported together with the hole depth (test specimen thickness). Retests may be made using thicker test specimens, up to a maximum of 10 mm.
