Description
HV9170 Test object package – insulators are crucial components of all HV transmissions lines. It is thus very important to understand how insulators are selected and dimensioned. The dimensioning of Insulators is critical in terms of electrical, mechanical and environmental stress. TERCO has for this package selected three typical high voltage Insulators.
They come in a sturdy aluminium case complete with all the necessary connections and a complete experiment manual.
