Abstract :
The deterioration of polymeric insulation by the growth of water trees has been investigated for the last 20 years. It is known that water tree growth occurs in service, reduces the breakdown strength of the insulation and can reduce the service life. The author investigates test methods to see if water trees can be predicted
