Thesubfunctions can be enabled and disabled with the Operation setting. The correspondingparameter values are Enabled and Disabled.The operation of the subfunctions is described by the module diagram as shown in Figure196. All the modules in the diagram are explained in subsequent sections.Section 16 1MRK 511 365-UUS AMonitoring528 Phasor measurement unit RES670 2.1 ANSITechnical manual
