GridKey - Model MCU318 -Metrology and Communications Unit
Our cost effective system continuously and accurately measures and calculates a wide range of grid condition data. 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. 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.
- Current measurement range accurate up to 720 A AC per feeder phase
- The MCU318 continuously and accurately measures and calculates a wide range of grid condition data including:
- Busbar min / max / averaged voltages
- Minimum, maximum and rms current and phase angle for individual phases per feeder
- Active and reactive powers per feeder
- Stores calculated values and alarms for up to 180 days
- The MCU318 is fully configurable at installation time via a Wi-Fi link with a laptop or via Android and IOS apps
- Parameters that can be set include:
- Substation identification and location information
- The feeder connections used
- The reporting intervals and alert message settings
- MCU measurement reporting interval from 1minute, 10 minute or 30 minute periods as needed
- Safe and easy retrofit solution for installations indoors and out
- No interruption of customer supply required
- IP54 protection for indoor and outdoor applications
- When used with SlimSensor Rogowski sensors the system provides class 2 metering
- Compact design allows the system to be fitted internally within LV cabinets reducing the risk of theft or vandalism
- A built-in GPRS modem and antenna provides reliable communications
- A secure Wi-Fi connection to the unit is provided to allow configuration and testing whilst installing
The MCU318 has been designed with the ability to add additional modules and connect to additional sensors to provide increased functionality. Click on the related options below for more information.
