I have a question on creepage distances. A product creates a saw tooth High voltage of 2000 Vpeak The VRMS measured on the scope on a full period equals 1120 V
Creepage is based on the RMS value of the voltage so is based on 1120 V. Now the frequency of the sawtooth is 3 Hz. Should I still consider the RMS value, and at what frequency should I consider this as a DC value in regard to creepage.... Anyone aware of the IEC 60664 standard in respect to low frequency signals ?? Regards, Ing.
