Added intelligence with Micrologic trip units Effective electrical distribution is more than just the transmission of power. Capturing, understanding and managing power information can substantially increase your system efficiency and lower lifecycle costs. Micrologic trip units provide advanced functionality for QED-6 switchboards. Communication interfaces, PowerLogic power metering, harmonics, waveforms capture and local/remote monitoring allow for integration and coordination of your electrical system. With the appropriate Micrologic trip unit, you can: Micrologic trip unit Communicate with breakers Collect power information and energy usage patterns Monitor events and deviations from the norm Remotely control breakers for better process loading Perform predictive maintenance Nearby Ethernet hub Existing network CM or PM with ECC or EGX Transparent Ready Equipment We are the first manufacturer in the world to provide Ethernet connectivity across our comprehensive portfolio of power distribution equipment. We call this innovative technology platform Transparent Ready equipment. It is simply the easiest and most open solution for accessing information about your electrical systems. All Transparent Ready equipment products feature an Ethernet connection and embedded web server, designed to organize valuable information for easy access from any computer on your network using any standard web browser. By making it simple to connect your power equipment, we help you get the actionable information you need to reduce costs and increase productivity. Intelligent devices are connected to the LAN via a PowerLogic Ethernet server Circuit monitor or power meter with Ethernet communication card: ECC Ethernet Gateway: EGX PC with web browser intelligent devices Obtain data from any of these devices via web pages: Masterpact breakers with Micrologic trip units Circuit monitors: CM3000, CM4000 series Power meters: PM 800 series increase your system efficiency
Power Monitoring Employing sophisticated power monitoring equipment to analyze historical and real-time data reduces the cost of electricity, improves power quality/reliability and enhances troubleshooting abilities. Our system allows you to: Power meter Circuit monitor display Better understand electrical system loading and demand Cut capital cost from over designing when expansions or modifications are needed Compare electric bills (kwhs) with utility company statements Catch voltage sags and disturbances that may be causing critical equipment to trip off-line Troubleshoot system problems such as faults or harmonics PowerLogic circuit monitors: CM 3000 and 4000 series Features all basic and advanced metering functions while providing a 0.04% typical accuracy rate 14 data logs and up to 32MB of memory Waveform capture to 255th harmonic Three types of waveform capture steady state, disturbance and adaptive Sag/swell detection to less than 1/2 cycle Trending and forecasting functions 15MHz sampling rate for detection of transients lasting only one microsecond (available with CM4000T) GPS time synchronization option Sequence event time stamping option PowerLogic power meter 800 series Basic metering functions allow metering of current, volts, power, energy and demand readings Power quality readings include total harmonic distortion for current and voltage readings Minimum/maximum values Alarm/relay functions Event and data logging on pre-configured values reduce the cost of electricity
