Overview
1–2
The Powermonitor Software data files format allows the user to apply
standard database application programs such as Lotus
TM or others to produce
system reports such as:
a. load trending
b. trouble analysis
c. cost analysis
d. cost allocation
e. demand scheduling
f. performance analysis and reporting
g. shadow billing
h. engine/generator efficiency studies
Powermonitor Display Module
The Powermonitor provides electrical monitoring and control functions in a
wide variety of applications. The Powermonitor can be operated
independently in stand–alone applications, or used with a computer running
Powermonitor Software for local or remote device programming, setpoint
control, viewing of data, and manual relay operation. All functions of each
Powermonitor may be accessed from the Powermonitor Software computer
station. The Powermonitor Software also provides access to features that are
not accessible when the Powermonitor is used in strictly stand–alone
applications.
The Powermonitor performs high accuracy measurement of Volts (L–L,
L–N), Amps, kW, kVA, kVAR, kW Demand, Amps Demand, Power Factor,
Frequency, kWH, kVARH, kVAH, and Neutral Current. Dependent on the
range, connections can be made directly to potential transformers and current
transformers without the need for intermediate transducers.
An auxiliary voltage input can be used to measure parameters, such as,
transformer temperature or battery voltage. Four status inputs can be used to
monitor circuit breaker status, ground fault relay status, or any other voltage
input within the status input range.
The Powermonitor has an extensive user–programmable setpoint system.
Three on–board relay outputs can be used for fully automated demand,
power factor, or load control, or to trip a critical breaker or activate an alarm
in the event of under/over voltage, voltage or current unbalance, phase
reversal, etc. The three relays can be programmed for multiple setpoints.
On–board data logging capabilities provide Event/Alarm, Min/Max, and
Snapshot data which can be accessed and displayed through Powermonitor
Software.
