IEC60112 Tracking Index Tester PLC Type For Testing Proof And Comparative Tracking Indexes
PLC Type Tracking Index Tester IEC60112 for Testing Proof amd Comparative Tracking Indexes
1. Introduction
The tracking index test apparatus is controlled by 7-inch color touch screen and PLC. The test apparatus is built-in air exhaust, the front panel is transparent for easy observation of the experimental process.
The tracking index test apparatus is designed according to IEC60112, UL746A, GB.T4207, GB4706.1 and TMD 3628-92. On the surface of the solid insulating material, a certain voltage is applied between the platinum electrodes (2 mm × 5 mm) , and drops the pollution liquid (0.1% NH4CL) with specified droplet volume in fixed height (35mm) for 30s to evaluate the resistance of the surface of solid insulating materials under the combined action of electric field and contaminated medium, and its Comparative tracking index (CTI) and proof tracking index (PTI) are determined. Tracking index test apparatus is mainly used in the industries of lighting appliance, low voltage appliance, household appliance, motor, electronic appliance, instrument and etc. It is a good tool for research department, production department and QC department.
