PQI Transformer Metering

TPM Integrated Transformer Performance MetersTM are installed on PQI e-RatedTM Distribution Class Transformers.


In addition to their revenue class metering and data logging capabilities, these integrated meters, with CSA C802.5 compliant software, determine each transformer’s Total Losses and Efficiency under their measured nonlinear loading profiles.

These best-in-class multifunction power and energy meters may be used as data gathering devices for intelligent electrical distribution systems or plant automation systems. All monitored data is available via a digital RS485 communication port running Modbus RTU and DNP 3.0 protocols. Additional communication options include Ethernet, Profibus DP, and BACnet. With its flexible, modular I/O and communication options, the Type TPM metering system is the most versatile and cost-effective solution available.
