The LM-5500 series comprises three unique 3-phase 600v recorders
(Models LM-5510, LM-5515, and LM-5520) each capable of
simultaneously recording 4 voltages, 4 currents with events and
power consumption. The 5515 and 5520 add full power quality analysis
features including harmonic and waveform capture capability. The
5520 also has load control relay outputs. The fourth voltage
and current channels allow neutral-ground voltage and neutral or
ground current to be recorded. The emphasis is on meeting practical
power monitoring needs by providing all the features required by
your front-line personnel yet at an attractive cost.

Sags / Swells
The LM-5500 series calculates rms voltage and current
values every cycle and saves time-stamped event data if they
are out of user specified limits. One cycle swell/sag data is
then available for every event. Min rms, max rms and average
rms values are stored for every storage interval. Text data on
up to 3000 events can be saved.
|
Power Quality Analysis
The LM-5515 and LM-5520 add waveform capture (on event or
time trigger), harmonic magnitude recording and paging (modem
option required). To avoid aliasing, waveforms are analyzed at
a sample rate of 128 samples/cycle and harmonics through the
25th are recorded for later trending and analysis. In
addition the LM-5520 has three sets of relay outputs for
performing programmed load control. |

Power Consumption Recording
The unit records more than 30 power parameters including
KW, KVAR, KVA, True and Displacement Power Factors. The
LM-5500 series uses Enetics SMART CT technology whereby each
CT’s calibration data is stored on a chip in the connector.
This error correction technique achieves a current accuracy of
better than 0.3% for CT plus recorder combined, and better
than 0.5% for power. The CT’s can be moved from channel to
channel or unit to unit without sacrificing accuracy. A wide
range of CT’s (including self-powered flexible CT) from 20A
to 6000A are available. |
Real-Time Data
Real time data is available from the RS-232 port to aid in
setup verification. Voltage, current, power, harmonic readings
and waveforms are updated every 7 seconds.

Software
The LMS-5700 software consists
of two major components, the database (SQL) and the
charting/reporting software. The database automatically aggregates
data collected from one or more designated sites. Data is easily
retrieved to generate the required charts and reports. For user
flexibility and extensibility, charts and reports are generated in
Microsoft Excel. The Excel worksheet data file can then be exported
in various formats and shared among users. Zooming and panning is
available on the charts. A key advantage of using an SQL database
and Excel is that it is an “open” system, you are not locked
into any suppliers’ proprietary software. You can retrieve any
data available from the database and/or use the Excel data to
generate additional charts and reports.
