1. Instrument description:
      The tracking tester complies with the GB/T4207 test standard.
      A rectangular platinum electrode is used, and the force of the two poles on the sample is 1.0N; 0.05N respectively. The applied voltage is adjustable between 100～600V (48～60Hz), the short-circuit current is 1.0; when 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 For 2 seconds, the relay will act and cut off the current, indicating that the test piece has failed. The time constant of the dripping device is adjustable, and the drip volume is accurately controlled between 44-50 drops/cm3 and the dripping time interval is 30±5 seconds.
