Online Power Quality Monitoring Device
Advanced Power Parameter Meter (0.2s Class)
PM172 High-End Power Parameter Meter (0.2s Class)
The PM172 is a high-performance feeder monitoring instrument with billing-grade measurement functions and recording capabilities. It measures over 100 electrical parameters, has long-term storage and recording capabilities, and includes circuit breaker open/close position inputs, making this series economically advantageous in distribution automation for public power utilities. The PM172 is widely integrated into distribution cabinets and SCADA systems of commercial and industrial production equipment. It is also used in engine systems.
