Application

The weak damped-capacitive impulse voltage divider are used to measure high voltage full and tail chopped lightning and full switching impulses. Provided with an adequate additional secondary part, it can also be used for alternating voltage measurements.

IEC60060-2 High-voltage test techniques Part 2: measuring systems

Design

The voltage divider consists of several stages of impulse capacitors connected in series. The weak damped resistors adopt the multi-stage layout, impulse capacitors are of no inductance, low voltage arm consists of non-inductive leaded multilayer ceramic capacitor.

The HV arm is installed on the basis of removable metal plate with wheels. The secondary unit includes a capacitor and a damping resistor of low inductance both arranged in a coaxial design. The unit is fixed at the bottom of the voltage divider and can be easily exchanged.

There is corona rings on top to avoid abnormal flashover or discharge when the impulse test is being carried out.
