27. utput CTs Milliamp meters require a single number representing the number of turns in the CT Sample values for various Elkor milliamp CTs are listed in the table below Current Transformer Number of Turns Millivolt meters require a conversion factor from Amps to millivolts for example 200A 333mV This indicates that 200A of current through the CT will create a 333 mV voltage on the output of the CT 5A meters require a unit less ratio of input current to output current for example 200 5 This indicates 200 A of current through the CT will create 5A on the output of the CT CT ratios can be edited as described in section 1 4 Editing Numbers p 5 HINT If entering different CT ratios in each channel it is permissible to enter the ratio using the Identical CTs settings first and then changing the Phases setting to Different CTs By doing this the initial starting ratio will be set identically in all three phases and it is thereby quicker to fine tune each ratio if required 3 5 Potential Transformers Potential Transformer PT ratios allow the device to scale the data to i report the real world voltage values on the input of the potential Phases Identical PTS transformers Because the WattsOn can accept up to 600V line to line k P Ts 1 1 voltage directly potential transformers are often not required In this case PT ratios may be left at their default values of 1 1 Potential transformer ratios can be pro
28. ypical values are i 1 minute 60 seconds 5 minutes 300 seconds 10 minutes 600 Length 605 seconds 15 minutes 900 seconds 30 minutes 1800 seconds 1 hour Count 1 3600 seconds or any arbitrary value expressed in seconds In addition the WattsOn can be configured to measure sliding window also called rolling demand power In this case the time interval is divided into several sub intervals The average power over the full interval is updated each sub interval This device can be configured for up to 60 sub intervals The interval length is equal to the sub interval length times the number of sub intervals If sub intervals are not needed set the sub interval count to 1 Example 1 To configure the device to record the average power over 15 minute intervals set the Length field to 900 15 minutes x 60 seconds and the Count field to 1 Every 15 minutes the S iding Window Power registers will update with the average power over the previous 15 minutes Example 2 To configure the device to record the average power over 15 minute Intervals updating every 5 minutes set the Length field to 300 5 minutes x 60 seconds and the Count field to 3 15 minute intervals 5 minute sub intervals Every five minutes the S iding Window Power registers will update with the average power over the previous 15 minutes 3 8 Reset Energy To reset the resettable accumulated data registers to 0 perform the following procedure Set all energy
