Group,
I am trying to construct a simple earth leakage test circuit as in Annex D
of EN60950. I am finding it impossible to find a capacitor for Cs (0.22uF) as I
cannot find one that is the required value, tolerence and voltage rating.
Am I missing somthing here? Even if I use a network of capacitors I would have
to use quite a few of them to get the right value! It would appear that the 1%
tolerence that is requested is a bit unrealistic given the value and required
voltage rating.
Has anybody else found this and if so how was it resolved? Are there any
manufacturers of earth leakage testers who may be able to hint on how they
manage to overcome this?
Any suggestions would be greatly recieved...
thanks,
Duncan.
