Resonant Withstand Voltage Test System

Resonant Withstand Voltage Test System
Product name:Resonant Withstand Voltage Test System
Item:6-10
Details:
 

I Description

This variable-frequency series-resonant withstand voltage test equipment is special for checking CVT (capacitor type voltage transformer).

This kind of resonant test system satisfies step-up requirements by big capacity CVT checking. It adopts several reactors series connecting method, and so it is small volume, light weight.

The reactor can be fixed type or adjustable type, according to requirement.

II Main technical index

No.
