PQI’s MARKET DIFFERENTIATORS
MEDIUM VOLTAGE TRANSFORMER REPLACEMENTS
If you’re replacing low voltage transformers as part of your solution you should also consider any existing medium voltage (MV) transformers. PQI manufactures transformers with primary voltages up to 46 kV (250 kV BIL). While most MV units are standalone, many facilities have transformers needing replacement that are located inside of switchgear cabinets. We can supply replacement core and coil assemblies. These can be custom designed for easy installation into existing switchgear cabinets, also taking into account building ingress.
PQI TRANSFORMER PERFORMANCE METERS (TPMs) ON EVERY TRANSFORMER
In order to enable our ESCO Partners to monitor the performance of the updated electrical distribution system, or empower their customers to do it themselves, PQI includes integrated ‘revenue class’ power meters (TPMs), with data logging capabilities, on all medium and low voltage transformers. These integrated power analyzers provide all of the power and harmonic measurements that are required to maintain an energy efficient system or diagnose and remedy future system or load problems.
The TPM’s user‐friendly software monitors power and harmonic profiles, locally and remotely via MODBUS or Ethernet, with standard protocols. The meters are compatible with all building management systems and can be supplied with several different communication protocols as options. An important function of the meter, and one that our ESCO Partners find particularly valuable is built in Measurement and Verification for each project.
NEXT LEVEL SAVINGS – CALCULATED REDUCTION OF LOSSES IN SYSTEM AND AT CONNECTED LOADS
When an existing transformer is replaced with a more efficient PQI transformer, it saves money because of reduced electrical losses. Those savings are realized on every project. One of the things that differentiates PQI from any other company in this market is that the savings are not limited to the transformer alone. We accomplish this by using custom engineered applications of harmonic mitigating transformers. Since harmonics are mitigated within each transformer, they no longer flow through the conductors and connected loads. As a result, the conductors and loads perform their tasks far more efficiently. Harmonic mitigating transformers reduce current and voltage distortion throughout the system.
These NEXT LEVEL SAVINGS in the system and the loads are calculated savings above and beyond the savings provided within each transformer. NEXT LEVEL SAVINGS are confirmed by monitoring the information provided by the built‐in PQI TPMs. This is part of our M&V process, so the results will be clear.
