Powermonitor™ Products

Our Powermonitor products meet the needs of producers and consumers of electric power. These products provide monitoring and control information for substation and distribution centers, electrical control panels, and many utility, commercial, and industrial applications including motor control centers.

The following power management application definitions help explain the advantages of using power monitoring products.

Demand management is a control system designed to minimize electrical demand penalties that can represent up to 30% of a typical industrial utility bill.

Activity-based cost accounting is a management system that allows a customer to allocate energy costs based on actual usage, which is based on sub-metering rather than other measurements such as square footage allocation.

Power control is a control system where electricity is the process output. There is usually on-site generation, emergency load shedding, or a system where a high-quality and stable electric power source is critical to the process.

Power quality is a management system that monitors power quality events or conditions that could cause a production shutdown like voltage sags, brownouts, transients, and high harmonic distortion.

Load profiling is a management system where electrical loads are monitored or profiled. These load profiles let the user prepare for utility deregulation and make fact-based decisions on future demand-side management control systems.

    Product Overview

    Powermonitor 3000 Products (Bulletin 1404)

    The Powermonitor 3000 has four versions, the M4, M5, M6, and the M8. The M4 unit provides basic metering including frequency, voltage, current, and power. It also provides calculated information such as energy consumption, power factor, and total harmonic distortion. The unit also has onboard logging capability that can store data, record the min and max of each parameter, and keep an event log.

    The M5 offers M4 functionality with flash upgrade capabilities to higher levels. The M6 unit contains all of this functionality in addition to power quality features such as, extensive waveform capture and storage and spectral analysis up to the 41st harmonic. The M8 adds more sophisticated power quality tools, greater speeds, accuracy and captures sub-cycle transients as well as harmonic analysis up to the 63rd harmonic.

    For more information, see publication 1404-PP005*.

    Powermonitor 1000 Products (Bulletin 1408)

    Energy management and understanding energy costs are a major focus today in the manufacturing industry. The Powermonitor 1000 is a cost effective energy monitoring and control solution. The Powermonitor 1000 is perfect for your applications where load profiling, cost allocation, or energy control is required. It can also provide seamless integration to your existing energy monitoring systems where sub-metering is required. The Powermonitor 1000 is available in five models (two transducers, and three energy-monitors), with features and a price point to meet your application.

    Transducer models feature the ability to measure voltage, current, and power related tags. Energy monitor models feature the ability to measure consumption related tags such as real, reactive, and apparent energy. The top-of-the-line energy monitor (EM3) provides all the features of both the transducer and energy monitor models.

    The Powermonitor 1000 integrates into your existing energy monitoring systems featuring, RSView, RSPower, or RSEnergyMetrix to further enhance the view into energy costs. Your existing Allen-Bradley PLC’s (PLC-5®, SLC™, ControlLogix® Family) can also easily communicate to the Powermonitor 1000 to allow energy data to be used in control systems.

    For more information, see publication 1408-PP001*.

    PowerPad Portable Powermonitor (Bulletin 1412)

    Wouldn’t it be nice if you could look inside your electrical system and see what's going on? Troubleshooting would be so much easier if you could see the volts, amps, and harmonic content in real time and take pictures to document and analyze. Now you can do just that and more. The full-color graphical display lets you see and analyze each signal clearly. Its high-speed sample rate, at 256 samples per cycle, provides excellent fidelity in reproducing waveforms and capturing transients that happen as fast as 62.5 ms.

    4 MB of memory is conveniently partitioned to let you store four different types of data, synchronized or independent of each other. You can store up to 12 screen snapshots, up to 50 captured transients that contain four cycles for each active input, and 4096 alarm events. You can also record trend data for days, weeks, or even months.

    Additional sets of three current probes are available, including 240 A, 1200 A, 6 A/120 A clamp-on probes, 24 and 36 in. "rope" 6500 A current probes, and a single 1000 A AC/1400 A DC clamp-on probe.

    For more information, see publication 1412-PP001*.

    Current Transformers (Bulletin 1411)

    The 1411 series is a full line of low-voltage Current Transformers (CTs) for various power measurement devices and applications.

    Power measurement devices include protective relays, analog devices, transducers, and power monitors. The purpose of CTs is to scale high currents to more manageable levels, while preserving a reasonable level of accuracy. CTs typically scale the currents flowing through their primaries to 5 amps (full scale) on their secondaries. The majority of power measurement devices are designed to accept this current level.

    Bulletin 1411 Current Transformers are available in ratios from 50:5 to 3500:5 in a variety of solid core, split core, and window sizes.

    For more information, see publication 1411-SG001*.

    Combination Generator Control Module (Bulletin 1407)

    The Combination Generator Control Module (CGCM) sets a new standard for generator control. The CGCM combines excitation control, generator protection, synchronization control, and full-featured metering in a single compact product. The CGCM, when used in conjunction with a ControlLogix® Automation Controller, provides a highly robust and flexible platform for generator control and system supervision.


    For more information, see publication 1407-PP001*.

    Capacitor Bank Controller (Bulletin 1413)

    The capacitor bank controller is a pre-engineered control system containing a MicroLogix 1400 controller, one or more Powermonitor 1000 products, and an optional human-machine interface(HMI). Pre-engineered ladder logic code in the controller gathers real and reactive power data from up to four power feeds(utility feeds and/or generators). The logic operates on the data in standard engineering units of kVAR and kW and minimizes imported and exported reactive power by switching up to 10 steps of capacitance. This strategy controls power factor while reducing the likelihood of voltage surge caused by excessive kVAR export.
