New developed measuring winding:
Standard measuring windings can have large errors as soon as they are under any kind of load. Our latest developed is a measuring winding, which guarantees a correct HV measurement over full range with active, capacitive or inductive loads and even with very high current THD, like they occure in applied voltage tests. The measuring winding is build complete inside of the housing and only possible with limited models (please see datasheet in downloads), futhermore a measurement is currently only possible with one frequency without reconnection.
