WebIEEE Std. 400.2 provides suggested time and voltage test levels but exact parameters are not possible since defect growth rates are not known and can vary widely. VLF tests at IEEE 400.2 test levels do not damage cable systems' 'good' insulation but are used to degrade existing insulation defects to failure during the test rather than in-service. WebApr 24, 2016 · If a DC test voltage is to be used instead of AC, IEEE Std. 95 recommends using 1.7 times the AC test value. I would have expected a DC value of 1.41 times the AC test voltage to be recommended (i.e. the RMS value). After doing some reading, I found that the 1.7 value is more accurate when the insulation is very close to the ground potential ...
