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(dǎo)電通路。跟蹤測試設(shè)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(dǎo)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。
