Figure 2. Typical Power Supply Connection Using a Terminal Block
Voltage Conditioners
System voltage inputs are required in order for some
advanced metering and protective relay functions to
operate correctly (any calculation involving voltage
such as power or undervoltage). Seven different
voltage conditioner plate assemblies are available.
The voltage conditioner used in the assembly has
the capacity to provide voltage-sensing signals to 20
Spectra breaker/trip units over a length of 40 feet (total
distance from voltage conditioner to last breaker). The
voltage conditioner requires +24 Vdc control power (see
section on Power Supplies). The voltage conditioner
plate assemblies include the voltage conditioner, fuse
protection and three 1-VA high-accuracy potential
transformers.
Table 8 lists the available voltage conditioner plate
assemblies. The voltage conditioner used in the
voltage conditioner plate assemblies is available as a
stand-alone component (catalog number SPSAA).
