Online Power Quality Monitoring Device
PM175 is developed to meet the diverse needs of different customers in the IEC market: substation operators, power system integrators, generator users, industrial and commercial power consumers, etc. This analyzer is suitable for all applications requiring high-performance power quality monitoring and fault tracing analysis.
The wide range of features of PM175 makes it an ideal choice for many applications such as feeder, switch monitoring, billing measurement and settlement, power quality, and utility SCADA. Since it supports industrial standard DNP3.0 and Modbus RTU protocols, it is also extremely suitable for substation automation.
PM175 provides comprehensive power quality monitoring capabilities and includes statistical reports compliant with EN50160. PM175 enables both power suppliers and power users to monitor the quality of outgoing or incoming electrical energy. This allows power suppliers to take timely remedial actions and power users to avoid equipment damage caused by power quality issues.
Two communication ports enable local and remote data acquisition.
