Impulse Dividers

IDE series are externally damped impulse voltage capacitive dividers and can be used to measure full and tail chopped lightning impulses as well as switching impulses at voltage levels up to 1MV. This voltage divider serves simultaneously as a load capacitor for the impulse generator. With suitable secondary arm it can also be used for AC voltage measurements.

IDI series are internally damped capacitive impulse voltage dividers and can be used to measure full and tail chopped lightning impulses as well as switching impulses up to the highest voltage levels. This voltage divider serves simultaneously as a load capacitor for the impulse generator. With suitable secondary arm it can also be used for AC voltage measurements.

Impulse Current Shunts

These shunts are used for the measurement of impulse currents in high-voltage test labs. The measured wave shape of the current can be displayed on a KVTEK's impulse analyzing system IM212 / IM412.

Multiple Chopping Gaps

MCG series multiple chopping gap is used to chop lightning impulses on the front and/or on the tail. It also serves simultaneously as a load capacitor for the impulse generator and allows excellent reproducibility of the chopping time and does not distort the wave shape until the chopping point. The sphere distance is automatically adjusted and operated by the WV 23 Impulse controls.
