Increasing the high voltage stepwise is a task that is often required during type testing and production testing of high voltage products. The STEPcompact is an instrument to automate such step tests. The unit combines the control function with the measurement capabilities of a high voltage meter. As a stand-alone instrument, the STEPcompact can be easily moved between different high voltage test sets.


The STEPcompact measures the voltage signal derived from a capacitive or resistive divider. Using a fiber optic transmission, the UP and DOWN relay contacts of the voltage regulator are actuated to adjust the high voltage according to the programmed test sequence.

The HVcompact is a high voltage meter with an auto-ranging oscilloscope display of the voltage waveform. The unit displays Û, Û/Ö2, Urms, frequency, and the crest factor. To improve the readability, one selected measurement is displayed using larger characters. To protect test specimens, the unit offers a pre-settable voltage limit, which trips a relay output. The divider ratio is widely adjustable and is kept with a non-volatile memory.

Mostly, the HVcompact is used in case of modernization or upgrade of high voltage test sets. With conventional analog or digital panel meters, usually, solely the voltage is displayed. The HVcompact adds several helpful functions.

The HVcontrol unit combines all standard functions required to manually operate a high voltage transformer. It includes a safety contact loop, the measurement of primary and secondary current, as well as of the primary voltage. User-settable limits for the primary and secondary current trip the main circuit breaker.

Due to its flexible design, the HVcontrol can be used on any high voltage test set. Especially, in case of the modernizationof old test sets, the HVcontrol offers a multitude of improvements if compared with conventional relay based controls.
