PQI TPM Integrated Transformer Performance Meters
Type TPM Integrated Transformer Performance Meters™ are installed on all PQI e-Rated™ 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.

In addition, IEEE Std. C57.110 compliant software also determines each transformer’s No-Load Losses and Load Losses, including its nonlinear ‘Penalty Loss’ component and EPA Environmental Benefits. In its ‘transformer comparison mode’, given the cost of each transformer and the cost of energy, the software will also compare the performance of any two transformers, including A/C costs, and calculate an annual saving, payback and return-on-investment, in a ‘substitution’ or ‘before end-of-life replacement’ scenario.
