4200 瑞典Friborg跟踪测试仪

瑞典Friborg跟踪测试仪

在正常使用时，绝缘材料可能暴露在潮湿环境中。
和污垢，可以创建带电部件之间的导电路径。
本试验设备模拟通过施加电压在两
放在被测试的材料的电极。导电的溶液
允许落在电极之间的材料，以便
电流在材料表面。

瑞典Friborg跟踪测试仪

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型跟踪测试仪
在正常使用时，绝缘材料可能暴露在湿气和污垢中，从而在带电部件之间形成导电通路。跟踪测试设备通过在被测试材料上的两个电极上施加电压来模拟这一点。导电溶液被允许滴落在电极之间的材料上，这样电流就可以在材料表面流动。
