The High Voltage impulse attenuator together with the ISOBE5600 transient recorder and the Perception High Voltage Impulse Analysis option (HV-IA) form an application specific measurement solution. Together the three components offer a cost effective solution for the HV impulse testing applications (Lightning impulse, Switching impulse and Current impulse). The HV impulse attenuator provides a simple and effective method of interfacing with the customer installation (voltage divider). The input LEMO connector type of the HV impulse attenuator matches the commonly used output connector type of voltage dividers while the output BNC connector matches the ISOBE5600t or 6600HV.

With an input voltage of 2 kV RMS and an attenuation ratio of 50:1, the typical output signals of the voltage divider in the test hall are reduced to more suitable amplitude levels. The HV impulse attenuators high input impedance of 2 MO allows the unit to work with capacitive as well as resistive voltage dividers. In cases where the voltage divider needs to feed signal into a low impedance input, the feed through LEMO connector can be used for an appropriate termination.
