Phwd-MU
Measuring transducer for phase angle
Description
Measuring transducer for phase angle
Application
The measuring transducer Phwd-MU is used for the transformation and isolation of the phase angle between current and voltage of an alternating current and three-phase power system of the same load into an impressed direct current and direct voltage signal.
Function
The parameters to be measured are transmitted to the zero point comparator via internal current transformers and voltage dividers. At the comparator, a square-wave signal is available which is directly related to the phase angle. A downstream integration stage then generates the direct voltage mean value. This direct voltage is transformed into an impressed direct current and an impressed direct voltage. The galvanic isolation between input and output signals is done using optocoupler. Both outputs are no-load proof and shortcircuit proof. Connecting the two outputs is not permissible. An auxiliary voltage is required.
