IEC60112 Flammability Testing Equipment Tracking Indices Tester With Platinum Electrode And PLC Control
Standard:
IEC60112-2009 Method for the determination of the proof and the comparative tracking indices of solid insulating materials.
Application:
It is used for determination of the relative resistance to tracking performance that solid electrical insulating material under the action of an electric field, when the surface exposed to water containing impurities.
If electrical products affected by moisture and impurities environmental, leakage may be caused on the insulation between different polarity live parts or live parts and grounded metal, the generated arc will cause short circuit or electrical erosion due to discharge, even cause fire. The tracking test is a destructive test to insulating material simulating the above situation, to measure and assess the relative resistance to tracking when the insulator is in the effect of electric and impurities in water-containing.
Feature:
This equipment adopts advanced PLC control system, touch-screen humanized button operating device, high quality materials and professional technology, which make itself has excellent quality, stable and durable performance and beautiful appearance. In addition, automatic drip timing device, accurate electrode pressure sensor display, simple operation and high accuracy improve the efficiency of the test and make our equipment takes a leading position in similar products.
Working principle:
The working principle of the leakage tracking test(tracking index testing) is that the conducting liquid (0.1%NH 4 CL) of required volume in the required height (35mm ) and required time (30s) drops with the voltage between the platinum electrodes (2mm× 5mm )on the surface of solid insulating material. Thus the users evaluate the tracking resistance performance of solid insulating material surface under the combined influence of electric field and humid or contaminate medium. In a word, this device is used to measure the compare tracking index (CT1) and electrical resistance index (PT1).
