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 ?

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 ?
