Hi , has anyone an answer to my question ? Have a good weekend

Has anyone some information about the following topics ? 1 - Standard for the creepage distance selection for High Voltage OHL insulators . We are using in Europe IEC 815 . What about USA ? 2 - Has anyone a link to a web site , where i can find a map with a zoning scheme and the related...

Good Morning I´m drawing a bushing for 24 kV . The bushing consists of a rod ( made of metal),a tube(epoxy/glass fiber) and a flange (stainless steel). I would to calculate the electrical field at the flange , to have an idea of the filed magnitude´and to define the right proportions for the...

Hi Thank you for the answer . I would know what kind of soldering metals are in use , to take a decision for a possible alternative with polymeric insulation . How high is the melting point of these kinds of soldering mixtures ? Tank you a lot

Hallo I´m drawing a Bushing for a Capacitor´s Bank . Normally these bushing are soldered on the case of the aparatus : what kinds of soldering metals are in use ? Are there problems with procelain , due to the high temperature ? Tanks Daniele

Hallo ! Someone know the title and the authors of a book about HV Insulators , that introduce the theory and the applications of HV Insulators ? Thanks Daniele

The base impedance is : z_base = Un^2/An = 0.106 ; The xd , or sincronous reactance (steady state) , in per units is equal to 2.96 . xd [ohm] = 2.96*0.106 = 0.316 that is close to 0.4 . It is correct ?
