- The extensive features of the PM174 make it ideal for applications such as feeder, switch gear monitor, revenue metering and billing, power quality and utility SCADA. It is also highly suitable for substation automation because of its support of industrial standard DNP 3.0 and Modbus RTU protocols.
- The PM174 provides the full range of power quality monitoring capabilities, implemented with the IEEE1159 specifications in mind. The PM174 allows both suppliers and consumers to monitor the quality of outgoing or incoming electric power. This enables power suppliers to prepare timely corrective action, and helps consumers prevent equipment damages caused by power quality issues.
