Power-monitoring units
Circuit Monitor Series 4000
Functions and characteristics
E90463
The PowerLogic Circuit Monitor Series 4000 offers high-performance digital
instrumentation, data acquisition and control capabilities. The products integrate
easily in power monitoring and control systems due to their Ethernet connections and
embedded web server. They are Transparent Ready.
These devices are designed for applications where power quality and availability are
critical factors. They are generally used at service entrances and interconnection
points or on circuits feeding sensitive equipment. Due to their very wide range of
features, including transient detection, it is possible to rapidly solve problems related
to poor power quality. EN50160 compliance checking capability makes these
products ideal to meet new needs related to market deregulation.
The Circuit Monitor Series 4000 is available in three versions:
b CM4000, with detection of voltage sags and swells
b CM4000XR, with detection of voltage sags and swells and an extended current
measurement range
b CM4000T, with detection of voltage sags and swells together with transient
detection and flicker measurements.
Applications
Panel instrumentation.
Sub-billing / cost allocation.
Remote monitoring of an electrical installation.
Extensive power-quality monitoring.
Contract and load curve optimisation.
EN50160 electricity supply compliance checking.
Metering of other utilities.
Main characteristics
Detection and capture of voltage sags and swells
Fast identification of problems causing production shutdown.
Detection and capture of short transients less than 1 µs (optional)
Identification of problems due to short disturbances, e.g. switching of capacitors, etc.
Flicker
Measurement of rapid voltage variations.
Electricity quality checking in compliance with EN50160
Fast standardised check on the quality of the electricity supplied.
Detection of major waveform changes
Detection of phase switching phenomena (for example during transfer to engine
generator sets) not detected by classical threshold-based alarms.
Ultra-fast recording of electrical parameters every 100 ms or every 20 ms
Preventive maintenance: acquisition of a motor startup curve, etc.
Trend curves and short-term forecasting
Rapid trending and forecasting of upcoming values for better decision making.
Automatic alarm setting
Alarm setpoint learning feature for optimum threshold settings.
Up to 32 Mbytes of memory
For archiving of data and waveforms.
Ethernet 10/100 Mbits/s card and server for HTML pages
Rapid data transfers over an intranet or the internet, simply using a web browser.
Alarm notification via email
High-priority alarms sent directly to the user's PC.
Up to 25 inputs/outputs to monitor the electrical installation
Status of circuit breakers, as well as metering of other commodities, e.g. gas, water, etc.
IEC 60687 and ANSI C12.20 Class 0.2S for energy
Verification of consumption and load curves.
