- DC to 300kHz bandwidth – up to 30kV - High transient voltage resistivity - Protection class IP65 for outdoor application - Insulation diagnostics by tan δ measuring - Negligible phase error, best suited for wideband power measuring The wide band precision high voltage divider HST 30 expand the voltage measuring range of ZES ZIMMER precision power meter LMG for use at power grid of nominal voltage up to 30kV. The high voltage input is equipped with 2.5m cable. The outdoor termination of this cable is attached to the voltage measured against earth. The HST 30 divides DC, AC or any distorted voltages with very high accuracy by the factor 10000. The divided voltage is available at the buffered low impedance TNC output. To avoid noise interference it is recommended to useshielded cables to the measuring input of the LMG. Application at - medium voltage power grids up to 30kV - railway contact lines up to 25kV - test voltages for insulation diagnostics up to 40kV - converter feed medium voltage motors e.g. to make - precise high bandwidth power measurements - analyse of voltage harmonics - precise measurement of dielectric losses
