Meßsystem für elektrische Störungen in einer Hochspannungsschaltanlage

摘要

In a measurement system for electric disturbances in a metal-encapsulated high-voltage switchboard plant (1, 2) with at least one measurement probe (3) for each phase, in order to remove electromagnetic disturbing signals both the disturbing signals and the useful voltage in each phase are sampled by the same measurement probe (3) and are made separately available at a filter arrangement (5, 10, 11).
