The options on this tab allow you to display and define power supply properties of new or existing tag numbers. Note that this tab is available only for those tag numbers that require power supply. Although power supply data is not essential for Smart Instrumentation functionality, it is indicated for an interface with the Smart Electrical application. (For more information about this interface, see Smart Electrical Interface (2018).
You make this tab available by selecting the Requires power supply check box on the General tab. If a value does not appear on a particular list, select the ellipsis button
next to the list to open a supporting table where you can add, modify, or delete
items that appear on the pertinent list.
Tag number
Displays the current tag number.
Criticality
Allows you to select an instrument criticality. This value will be used in Smart Electrical to determine whether the current instrument requires UPS power or regular power.
Rated voltage
Allows you to select a value that indicates the voltage at which the instrument is designed to operate.
Power supply type
Allows you to select the type of power supply: AC (alternating current) or DC (direct current). Note that selecting DC disables the Frequency, Number of phases, and Power factor full load options.
Frequency
Allows you to select the operating frequency of the instrument. This property applies for an AC supply only.
Number of phases
Allows you to select the number of phases in the power supply to the instrument. This property applies for an AC supply only.
Power factor full load
Allows you to enter the ratio of active to apparent power at 100% of the rated power. The power factor can have a value between -1 and 1. This property applies to an AC supply only.
Rated active load
Allows you to enter the full load power consumption for the current instrument in kilowatts.
Full load current [A]
Allows you to enter the full load current value for the current instrument in amperes.
Starting current [A]
Allows you to enter the starting current consumption for the instrument in amperes.
Rated reactive load [kVAr]
Displays the full load power consumption for the current instrument in kilovolt-amperes reactive.
Rated apparent load [kVA]
Displays the full load apparent power consumption for the instrument in kilovolt- amperes.
Coincidence factors
Allows you to enter values corresponding to the percentage utilization for the selected operating mode. The values can be between 0 and 1.
Operating mode
Allows you to select an operating mode that describes how the instrument is used as a load in the <plant>. The operating modes that are supported by Smart Electrical are:
Continuous
Intermittent
Spare
Standby
Power distribution board data
Provides information about the associated power distribution board and its components. The values in these fields are determined by the data that you downloaded from Smart Electrical.
PDB / Cell / Circuit
Displays the name of any associated power distribution board, cell, and circuit, as appropriate.
Phase arrangement
Displays one or more bus phases with which the current instrument is associated.
