  • Page 29: Signal Filtering

    A digital anti-aliasing filter with a cut-off frequency of approx. 3 kHz is implemented.

The configuration of these signals in ibaPDA is ignored in this process.

    Manual 13.2.3 Delta connection Delta connection direct connection 13.2.4 Connection with instrument transformers It is important that the instrument transformers are Open Loop transformers. This means that a sinus signal on the primary side also needs to exist on the secondary side. The instrument transformers also need to offer a broadband frequency transmission in order to capture harmonics or interharmonics up to the 50th harmonic.
