21.9.5 Operation principle
Every Signal matrix for analog inputs function (SMAI) can receive four analog signals (three phases
and one neutral or residual value), either voltage or current, see figure
outputs give information about every aspect of the 3ph analog signals acquired (phase angle, RMS
value, frequency and frequency derivates etc. – 244 values in total). The BLOCK input will force all
outputs to value zero if BLOCK is TRUE (1). However, when the disturbance recorder is connected
to the single-phase outputs of SMAI, the sample data to the disturbance recorder will not be
blocked. The disturbance recorder bypasses SMAI to the sample data channels.
System phase rotation and frequency are defined using the
in the primary system values PRIMVAL function. Logic 1 in the REVROT input to the SMAI function
means that the phase rotation is changed relative to the set
The output signal AI1 to AI4 are direct output of the, in SMT, connected input to GRPx_A, GRPxB,
GRPxC and GRPx_N, x=1-12. AIN is always calculated residual sum from the first three inputs. A3P is
grouped, three-phase information containing all relevant information about four connected
inputs. Note that all other functions, with a few exceptions, use this output in configuration. Note
