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
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, 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 reporting channels
