Baltimore, MarylandWhen performing energy management and power quality studies, a very new company called Z Meters, Inc. (no Web site yet) is readying a product that will use time-synchronized multi-point measurement and correlation techniques to characterize the impedance of an AC power distribution system. That's needed because problems in a power distribution system are frequently the cause of poor power quality and excess energy use.
The ZM100 Distribution Analysis System, slated for release early next year, will identify and localize conditions that can lead to voltage anomalies and/or power loss. These include loose wires, carbonized contacts, undersized transformers, harmonic loads, parallel loads, and non-linear impedances.
Why And Where
"Typical power quality and energy monitoring instruments provide data on what events are occurring and when they occurred," notes Bob Moore, president and CEO of Z Meters. "In contrast, the ZM100 tells you why and where the abnormal conditions exist in the distribution system that set the stage for those events to take place."
A ZM100 system will consist of two or more ZM100 Distribution Analyzers, each connected to a salient point in a facility's electrical distribution system. Each will be equipped to make time-synchronized and accurate measurements of voltages and currents for all phases and the neutral.
Measurements will be made, and data will be gathered, over a time period that will characterize the range of operating conditions that typically exist in the facility.
Data will be communicated to a PC across a Bluetooth RF wireless link. The ZM100's Windows-based software will perform calculations and correlations resulting in a characterization of a distribution system's impedance (both at the line frequency and at harmonics). Using the characterization, distribution impedance abnormalities will be identified, and corrective measures can then be applied.
The price for a complete system, including two measuring instruments, connectors, current transformers, and software will be about $10,000. The company says product will be available in the first quarter of next year.
