瑞典Friborg跟蹤測試儀

During normal use, insulation material may be exposed to moisture
and dirt that can create a conductive path between live parts.
This test equipment simulates this by applying a voltage on two
electrodes placed on the material to be tested. A conductive solution
is allowed to drop on the material between the electrodes so that a
current can flow on the surface of the material.
Technical specifications
• Fully automatic testing
• Electronic controlled precision pump
• Closed cabinet for testing and fan to take out gases
• Platinum electrodes as required by the test standard
• Electrode voltage 100-600 VAC
• Large 1800 VA transformer for sufficient short circuit current also
at lower voltages, as required by the test standard
• Insulating transformer and interlock switch for safe operation
• Interval between drops: 30 seconds
• Counter for number of drops
• Fault indication over 0,5 A in 2 seconds
• Short circuit current adjustable to 1 A
• Indicators for test status: Testing / Ready / Fail 

4200型跟蹤測試儀
在正常使用時，絕緣材料可能暴露在濕氣和污垢中，從而在帶電部件之間形成導電通路。跟蹤測試設備通過在被測試材料上的兩個電極上施加電壓來模擬這一點。導電溶液被允許滴落在電極之間的材料上，這樣電流就可以在材料表面流動。
