Dielectric test according to ASTM D149-09 2014 1. TEST OBJECTSample 1: GSL1 10,5 mm Sample 2: GSL 7mm The sample material was provided by the client. 2. TASK Electrical strength (AC) according to ASTM D149-09:2014 Test ParametersEnvironmental conditions Table 1 Environmental conditions T Min. T Max. r.H. Min. r.H. Max. 21 °C 25 °C 40 % 60 % 3. Electrical strength (AC) The test is carried out in the non-accredited area. Equipment: Dielectric tester DT 2 -50-20-SR-Pi-C, Sefelec Specimen: Dimension: approx. 60 mm 60 mm thickness Number: 3 Test parameters: Range of measurement: max. 51 kV AC, 50 Hz Electrodes: spherical Ø 20 mm – spherical Ø 20 mm Voltage slew rate: approx. 2000 V/s Test medium: Shell Diala S2 ZU-I Dried insulating oil according to DIN EN 60296:2012 4. ResultsThe test activities were successfully carried out in accordance with section 2. Remark: In case of test specimens no. 1 and 3 the electrical voltage caused a normal breakdown through the thickness. In addition, it flowed sideways through the test specimen until it reached the black string…
