GB/T4207 Widely Used Tracking Index Test Device

Application:

The leakage tracking tester meets the GB/T4207 test standard. A rectangular platinum electrode was used, and the force of the two poles on the sample was 1.0 N; 0.05 N, respectively. The applied voltage is adjustable between 100 and 600V (48-60Hz), and the short-circuit current is 1.0; 0.1A, the voltage drop should not exceed 10%. When the short-circuit leakage current is equal to or greater than 0.5A in the test circuit, the time is maintained. 2 seconds, the relay is activated, the current is cut off, indicating that the test piece fails. The time constant of the drip device is adjustable, and the amount of drip is controlled to be 44 to 50 drops/cm3 and the time interval between drops is 30 seconds.
