Description of configuration B20
The configuration of the IED is shown in
RES670 B20 configuration is applicable for a typical double
busbar single breaker arrangement monitoring up to six
bays. RES670 B20 is delivered in ¾, and full (1/1)19" rack
casing. For this application 24 analog inputs are used, thus
two transformer modules (TRM) with 12 analog inputs (9I
+3U) per TRM are available in B20 standard configuration.
As shown in figure 3, RES670 B20 configuration as a PMU
is measuring two 3-phase voltages of the busbars and six 3-
phase currents of bays 1 to 6. There are two instances of
PMU reporting functionality available in B20 configuration,
meaning two independent IEEE C37.118/1344 data
streams. Each instance of PMU is reporting frequency-
deviation and rate-of-change-of-frequency data. In the
standard B20 configuration, in addition to frequency data,

figure 3. first instance of PMU (first data stream) is reporting 32
synchrophasors over IEEE C37.118/1344; that is eight 3-
phase synchrophasors and 24 single phase synchrophasors
corresponding to the AC voltage and current
measurements. Second instance of PMU (second data
stream) is reporting 16 synchrophasors over IEEE
C37.118/1344; that is four 3-phase synchrophasors and 12
single phase synchrophasors corresponding to the AC
voltage and current measurements. The number of
synchrophasor reporting channels on second instance of
PMU can be extended to 32 channels per request. This can
be done when ordering the RES670 B20 configuration.
In addition, each data stream includes 16 analog and 16
binary reporting channels over IEEE C37.118/1344 in the
standard configuration. The number of analog and binary
