The CM-UFD.M33 is a secondary anti islanding protection for solar systems generally larger than 30kW. ABB manufacture and supply a range of grid protection relay's designed to counteract issues such as under and over voltage and rate of change of frequency. Grid feed monitoring relay's provide additional segregation between large scale solar systems and the grid itself. They also provide secondary protection to the solar system itself from issues such as surge.
This fully programmable 3 phase unit can be set to meet a number of supply authority requirements thereby making a large scale system compliant with the latest supply authority regulations. Featuring password protection and memory for up to 10 alarms the unit meets a number of regulatory requirements and is featured on Energex's BMS 04240 Network protection Relays list and also complies with Ausgrid's requirements.
The unit will handle Over or Under Voltage, Over or Under Frequency, ROCOF and Vector Shift.
