14 SIPROTEC 7SJ81/7SK81 V4.70, Product Information
E50417-K1150-C462-A2, Edition 02.2012
Parameters of the Low-Power Voltage Transformers
With parameter 330 U-LPVT SEC, you can set the rated input voltage.
Parameter 332A U-LPVT PHA allows you to correct the phase offset
between current transformer and voltage transformer.
The rated low-power input voltage is not used subsequently. The input
signal is converted to a virtual secondary voltage. Parameter 0203
Vrated SECONDARY allows you to set the virtual secondary rated
voltage. It serves as reference for all functions that use secondary values,
such as the parameterization in DIGSI and the display of the secondary
measured values. The setting affects the measuring range of the device.
