High-voltage divider DNV-80I is designed for the conversion of direct current (up to 80 kV), alternating current (up to 60 kV) and pulse current (up to 160 kV) voltage amplitude to the level, safe for the postprocessing, storage, transmission and further transformations of the measuring signal

Pulse high-voltage divider DNVI-40 is designed for the high voltage conversion to the level, safe for the postprocessing, storage and transmission of the measuring signal

PDD is designed to ensure quality control of grounding in the used electric system throughout the entire time of operation of electrical equipment. PDD compares the potential difference between the primary and reference earths. In case of a potential difference of more than 25V, an audible alarm is activated and the power supply is automatically switched off. There are variants of PDD for internal and external mounting.
