Section 6 Read measured valuesAbout this chapterThis chapter describes measurement categories and how to locate them using theHMI. Each measurement category has a section of its own that includes a generaldescription of the type of quantity being measured and the path in the local HMI tothe measurement.6.1 OverviewThe measurement menu contains primarily analog measurement data. Externalsignals can also be viewed as they are or as they appear in the Signal Matrix Tool(SMT). These signals are a virtual representation of the hard wired signals on thevarious inputs and outputs. SMT is only accessible via PCM600 and is intended tosimplify the configuration of the IED. It allows hardware changes to be madewithout having to reconfigure the internal logic. Signals that can be used in SMTare indicated with the Suffix SMT.The functions available under measurements are outlined below.1. Analog primary values are the quantities measured on the primary side of thecurrent transformers (CTs).2. Analog secondary values are the quantities measured on the secondary side ofthe current and voltage transformers. These are the quantities measured on theTransformer module (TRM) inputs.3. Analog mean values are the quantities measured at the inputs of themilliampere module (MIM).4. Under Monitoring a number of submenus are available. These include Servicevalues, Current phasors, Voltage phasors, Current sequence components andVoltage sequence components and busbar protection.5. Metering displays the pulse counter and energy calculation and demandhandling functions. The measurements available for pulse counter show pulsecounter status data.All measurement descriptions in this document reflect the maximum number ofhardware units possible in any application. In reality the hardware in the IED willbe chosen according to a particular application. For example, it is possible to equipa 1/1 x 19” case IED with 14 I/O modules. In reality fewer I/O modules may beinstalled. In the measurements menu the operator will only see data from thehardware and software installed.1MRK505209-UEN E Section 6Read measured values31Operator's manual |
