BCMS Measurements: Normal and Power-KWH Points Lists
BC = branch circuit, PB = panelboard
Direct Measurements
Current, branch circuits 1-42 Direct measurement from branch circuit CTs
Current, main feeds ABCNG Specify which main circuit phases are monitored with CTs in setup. If there are
no main feed CTs, BCMS computes main feed ABC values for each panelboard
from branch circuit current totals. (Note: this computed value is not a simple
sum of BC measurements.)
Voltage source 1 and voltage source 2 Voltage source 1 is required. JCOMM BCMS can monitor two voltage sources.
Voltage is measured at one source per panelboard.
Frequency Frequency is measured from voltage source 1 or 2, phase A.
Accumulated and Derived Data – Branch Circuits
Minimum current (BC 1-42) The lowest current measured on each branch circuit
Maximum current (BC 1-42) The highest current measured on each branch circuit
KW (BC 1-42) The Power-KWH points list provides detailed power measurements for each
branch circuit as shown in this section (grey background).
These measurements are not available in the
Normal points list.
KVA (BC 1-42)
KVAR (BC 1-42)
Power Factor (BC 1-42)
Accumulated and Derived Data – Panelboards
Current, ABC, each panelboard PB total current is measured from main feed CTs or computed by BCMS from
branch circuit current measurements.
Current, ABC, panelboards summed Current for both PBs summed is measured from a single main feed to both PBs
or a computed sum of the current to both PBs. (Not available if panelboards
use separate voltages)
Percent total load on panelboard Full load on a panelboard is specified during setup. BCMS reports panelboard
usage as a percentage of full load , but does not use this number as an alarm.
