INTERFACE 3 USER INTERFACES 3 3.2.5 TRENDING Trending from the 469 can be accomplished via the 469PC software. Many different parameters can be trended and graphed at sampling periods ranging from 1 second up to 1 hour. The parameters which can be Trended by the 469PC software are: Currents/Voltages: Phase Currents A, B, and C Average Phase Current Motor Load Current Unbalance Ground Current Differential Currents A, B, and C System Frequency Voltages Vab, Vbc, Vca Van, Vbn & Vcn Power: Power Factor Real Power (kW) Reactive Power (kvar) Apparent Power (kVA) Positive Watthours Positive Varhours Negative Varhours Temperature: Hottest Stator RTD Thermal Capacity Used RTDs 1 through 12 Demands: Current Peak Current Reactive Power Peak Reactive Power, Apparent Power Peak Apparent Power Others: Analog Inputs 1, 2, 3, and 4 Tachometer 1. With 469PC running and communications established, select the Actual > Trending menu item to open the trending window. 2. Click Setup to enter the Graph Attribute page. 3. Select the graphs to be displayed through the pull-down menu beside each Description. Change the Color, Style, Width, Group#, and Spline selection as desired. Select the same Group# for all parameters to be scaled together. 4. Click Save to store the graph attributes and OK to close the window.

Select the Sample Rate through the pull-down menu, click the checkboxes of the graphs to be displayed, and select RUN to begin the trending sampling. Figure 3–8: TRENDING 6. The Trending File Setup button can be used to write graph data to a standard spreadsheet format. Ensure that the Write trended data to the above file checkbox is checked and that the Sample Rate is a minimum of 5 seconds.

A maximum of 64 cycles can be captured and the trigger point can be adjusted to anywhere within the set cycles. A maximum of 16 waveforms can be buffered (stored) with the buffer/cycle trade-off. The waveforms captured are: Phase Currents A, B, and C; Differential Currents A, B, and C; Ground Current; Phase Voltages A-N, B-N, and C-N. 1. With 469PC running and communications established, select the Actual > Waveform Capture menu item to open the Waveform Capture window. 2. The waveform of Phase A current of the last 469 trip will appear. The date and time of this trip is displayed on the top of the window. The RED vertical line indicates the trigger point of the relay. 3. Press the Setup button to enter the Graph Attribute page. Program the graphs to be displayed by selecting the pull down menu beside each Graph Description. Change the Color, Style, Width, Group#, and Spline selection as desired. Select the same Group# for all parameters to be scaled together. 4. Click Save to store these graph attributes then OK to close this window. 5. Select the graphs to display by checking the appropriate checkboxes. 6. The Save button can be used to store the current image on the screen, and Open can be used to recall a saved image. Print will copy the window to the system printer. Figure 3–10: WAVEFORM CAPTURE 808730A2.CDR MODE SELECT Click to view
