Gridkey offers the MCU318 as a Low Cost, Low Voltage metrology-communications-unit
MCU 318 – Low Voltage Monitoring Alex Whitworth
Process data – Generate – Log parameters
Our cost effective system continuously and accurately measures and calculates a wide range of grid condition data, with Class 2 accuracy (view our Class 1 products here), including:
busbar min / max / averaged Voltages
minimum, maximum and mean RMS current and phase for individual phases per feeder
active and reactive powers per feeder
The MCU 318 uses the GPRS/Mobile data network as standard but also features the ability to support additional network requirements, e.g. Wired Ethernet. Interface modules permit customised interface solutions, providing highly flexible means for additional sensing and measurement capabilities.
The MCU is fully configurable at installation time via a WI-FI access point with a laptop or other device. Parameters that can be set include:
substation identification and location information
the reporting intervals and alert message settings
Measurements are also available for viewing in real-time. At any point in operation, the data reporting and alert messaging settings for each MCU can be individually re-configured via its network interface. The operator can select the MCU measurement reporting interval from every minute, hour or day as needed. Any stored data can be retrieved.
WHY CHOOSE THE GRIDKEY MCU318?
The economical GridKey LV Monitoring System is a designed for purpose, flexible and highly configurable
information system providing the following benefits:
Easy retrofit solution for installations indoors and out, lightweight, compact, robust, secure. No interruption of customer supply
BUILT TO LAST
Built to last in the environment, IP54 rated; meets relevant electrical standards for external (e.g. pole mount) and internal substation use.
Class 2 metering accuracy with monitoring of all three phases (MCUs can be ganged for installations)
Comprehensive reporting of substation feeder parameters, giving better information to drive evidence
based decision making for grid management
Allows the system to be fitted internally within cabinets reducing the risk of theft or vandalism. An antitamper cover is provided as standard.
Our MCU318 is a purpose designed low-cost alternative to our Class 1 product range. Offering Class 2 monitoring accuracy and a faster install time (sub 30 mins) the Metrology and Communications Unit (MCU318) allows for continuous monitoring of Low Voltage networks. The ease of install and operation sits at the forefront of this products design and functionality. Offering automatic feeder detection and routine reporting to the data-centre – allowing for the creation of a range of data sets, all offering the customisation and interopability to accurately and efficiently meet individual needs.
The Unit itself has modular capabilites but offers from day one:
True RMS Voltages at busbar phases
True RMS current at feeder phase, busbar phase and unit level
Synthesised Neutral current at feeder and busbar level
Active, reactive, apparent power and energy at feeder phase, busbar phase and unit level
Power quality measurements at feeder phase, busbar phase and unit level
As well as this, measurements are available as instantaneous values, or min, max and mean data for different time options.
