CHAPTER 6: ACTUAL VALUES METERINGD60 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL 6-256These actual values display without the corresponding time stamp as they become available per the recording ratesetting. Also, the recording post-filtering setting is applied to these values.6.4.10 PMU aggregatorACTUAL VALUES METERING PHASOR MEASURMENT UNIT PMU AGGREGATOR 1Actual values for the IEC 61850-90-5 PDU size are provided. These values allow you to know the approximate Ethernetframe size for the data streams from each aggregator. This can help to estimate network loading. The PDU size shown inthe displays does not include the Ethernet, UDP, or IP layers. PDU sizes approaching approximately 1500 bytes result infragmented data frames, causing increased network traffic.6.4.11 Transducer inputs and outputsACTUAL VALUES METERING TRANSDUCER I/O DCMA INPUTS DCMA INPUT xxActual values for each DCmA input channel that is enabled are displayed with the top line as the programmed channel IDand the bottom line as the value followed by the programmed units.ACTUAL VALUES METERING TRANSDUCER I/O RTD INPUTS RTD INPUT xxActual values for each RTD input channel that is enabled are displayed with the top line as the programmed channel IDand the bottom line as the value.6.4.12 DistanceACTUAL VALUES METERING DISTANCE PMU 1 I1:0.000 A 0.00° PMU 1 I2:0.000 A 0.00° PMU 1 I0:0.000 A 0.00° PMU 1 FREQUENCY:0.000 Hz PMU 1 df/dt:0.00 Hz/s PMU 1 CONFIG CHANGECOUNTER: 0Range: 0 to 65535 PMU AGGREGATOR 1 PMU AGGREGATOR 1PDU SIZE: 0 DCMA INPUT xx DCMA INPUT xx0.000 mA RTD INPUT xx RTD INPUT xx-50 °C DISTANCE AB LOOP RESISTANCERAB: 0.00 Ohms AB LOOP REACTANCEXAB: 0.00 Ohms AB LOOP IMPEDANCEZAB: 0.00 Ohms
