ABB
Phasor measurement unit RES670
Pre-configured
Product version: 1.2
Description of A20 configuration
RES670 A20 configuration is applicable for a
typical single busbar single breaker arrangement
monitoring up to three bays on the busbar.
RES670 A20 is always delivered in 1/1 of 19"
case size. Thus only 12 analog inputs are
available. As shown in figure 2, RES670 A20
configuration as a PMU is capable of reporting 4
synchronized phasors; that is, one 3-phase
Bus1
Note:
Ð This is a default pre-configuration provided according to a typical single busbar arrangement with three bays.

Figure 2. Typical PMU application for single busbar single breaker arrangement monitoring up to three bays,
including synchronized phasor reporting and back-up protection, using 12 analog input transformers in
full 19" case size.
RES670 A20 function library includes additional
functions, which are not configured, such as
additional Overcurrent protection functions,
Description of configuration B20
RES670 B20 configuration is applicable for a
typical double busbar single breaker arrangement
monitoring up to six bays on the busbar. RES670
B20 is always delivered in 1/1 of 19" case size.
Thus 24 analog inputs are available. As shown in
figure 3, RES670 B20 configuration as a PMU is
voltage of the busbar and three 3-phase currents
of bays 1 to 3. In addition, there are Binary Inputs
and protection function triggers which are
reported through PMU. This configuration also
includes general back-up protection functions
which are mainly intended for alarm purposes.
Available functions on A20 are Over Voltage,
Under Voltage, Over Frequency, Under
Frequency, and Rate of Change of Frequency.

capable of reporting 8 synchronized phasors; that
is, two 3-phase voltages from busbar 1 and 2 as
well as six 3-phase currents from bays 1 to 6. In
addition, there are Binary Inputs and protection
function triggers which are reported through
PMU. This configuration also includes general
