This section contains basic phasor measurement unit (PMU) data, such as functions, source settings, and names.
• PMU 1 FUNCTION: This setting enables the LOGICAL Device PMU 1 functionality. Use this setting to permanently
enable or disable the feature.
• PMU 1 IDCODE: This setting assigns a numerical ID to the PMU. It corresponds to the IDCODE field of the data, con-
figuration, header, and command frames of the IEEE C37.118 protocol. The PMU uses this value when sending data,
configuration, and header frames; and it responds to this value when receiving the command frame. This is used when
only data from one PMU is present.
• PMU 1 STN: This setting assigns an alphanumeric ID to the PMU station. It corresponds to the STN field of the config-
uration frame of the IEEE C37.118 protocol. This value is a 16-character ASCII string as per the IEEE C37.118 stan-
dard.
• PMU 1 SIGNAL SOURCE: This setting specifies one of the available L30 signal sources for processing in the PMU.
Note that any combination of voltages and currents can be configured as a source. The current channels could be con-
figured as sums of physically connected currents. This facilitates PMU applications in breaker-and-a-half, ring-bus, and
similar arrangements. The PMU feature calculates voltage phasors for actual voltage (A, B, C, and auxiliary) and cur-
rent (A, B, C, and ground) channels of the source, as well as symmetrical components (0, 1, and 2) of both voltages
and currents. When configuring communication and recording features of the PMU, the user could select – from the
