Equipped with 8 independent channels, the 3-phase PowerGuide® 4400 is part of the only family of advanced power monitoring instruments to incorporate a color touch screen into its lightweight design. Automated setups provide instant detection of circuits and configurations, ensuring that the instrument is ready to successfully collect data in seconds. Users can select the length and mode of data collection, including troubleshooting, data logging, power quality surveys, energy and load balancing. The Intelligent AnswerModule® feature provides consultant-like analysis of sag directivity, capacitor switching transient identification/directivity and motor analysis/reporting. The PowerGuide collects data at 256 samples/cycle/channel, offers remote communications using RS-232, ethernet or USB options, and meets IEEE 1159, IEC 61000-4-30 Class A and EN50160 standards.
Troubleshooting
The PowerGuide 4400’s unique annunciator "report card" provides instant power quality answers in the field. A wide range of power monitoring data is collected, analyzed and tabulated in color-coded categories to quickly identify areas of concern, which are identified in red. Drill down for more detailed information by simply touching the intuitive graphical screen to troubleshoot problems, locate the source, and pinpoint the root cause of power quality disturbances.
Fault Recording
The PowerGuide 4400’s simple fault recording mode provides instantaneous detection of electrical malfunctions and identification of faults within a facility’s power infrastructure. The PowerGuide will characterize the magnitude and duration of a fault and help direct the user toward its source. Information ncluding voltage and current frequency stability, power flow and harmonics underlie the PowerGuide’s diagnostic capabilities.
Inrush
The startup of motors, transformer energization, breaker trips, and the activation of backup generators and other applications with inrush conditions require extended cycle-by-cycle recording to ensure proper operation and to determine their impact on other devices. The PowerGuide 4400 goes beyond other power monitoring instruments by providing current-based RMS triggers and peak threshold crossings to optimize the performance and longevity of that essential equipment.
Compliance Monitoring
The PowerGuide 4400 has been designed to meet the most advanced power quality standards, including IEEE 1159, IEC 61000-4-30 Class A and EN50160. A statistical output is produced to quickly verify compliance with international quality-of-supply standards and benchmark power quality. In an instant, the PowerGuide provides a snapshot of over 13 key parameters, including unbalance, voltage variations and harmonics.
Data can be viewed in real time using scope mode, meter mode, event mode, harmonics spectrum or phasor diagrams. With the touch of your finger or a stylus, you can view data and zoom-in on captured disturbances for more detail and automated event characterization. All measuring modes are self-contained in the instrument, eliminating the need for TaskCards. Capture data on a memory card for analysis, trending, visualization and reporting using industry-leading DRAN-VIEW® software. DRAN-VIEW makes it simple to trend events, correlate data, analyze worst case scenarios, simultaneously view data from multiple sites, generate custom reports, and understand complex issues such as transients, harmonics and interharmonics.
Energy Surveys
The cost of energy is oftentimes a facility’s largest operating expense. Reducing energy consumption during peak times, shifting loads, purchasing energy efficient equipment, or changing energy suppliers can shave 10-40% annually off that cost. The PowerGuide 4400 is an invaluable tool for performing energy surveys, including monitoring energy consumption, usage patterns, peak demands and the activation of large loads, to reduce electricity costs. Plus, the PowerGuide makes it easy to track and allocate energy costs by process or department.
Equipment Performance Testing
Determining the availability and compatibility of facility power prior to the installation of new equipment is simplified using the PowerGuide 4400. The instrument incorporates advanced features such as RMS triggers, low/medium frequency transients, and cross triggering between channels to demonstrate that power mitigation devices such as UPSs are operating properly. Real time readings observed during maintenance and startup processes enable users to see results and tweak that equipment during the testing process.
Modes of Operation
Data can be viewed in real time using scope mode, meter mode, event mode, harmonics spectrum or phasor diagrams. With the touch of your finger or a stylus, you can view data and zoom-in on captured disturbances for more detail and automated event characterization.
