COMTRADE in PQ Canvass
The Common Format for Transient Data Exchange (COMTRADE) defined by IEEE C37.111 and IEC 60255-24 is a file format most commonly produced by protective relays and digital fault recorders, though…
Recognizing Transformer Energization in Power Quality Data
Transformer energization events occur frequently in electrical distribution systems and often appear in power quality recordings. These events can produce large transient currents and waveform distortions that may initially resemble…
Power Quality Challenges of Bidirectional EV Charging
The increasing adoption of Vehicle-to-Grid (V2G) technology enables electric vehicles to operate as mobile inverter-based energy resources, fundamentally altering their interaction with distribution networks. While the power quality impacts of…
High Order Harmonics
Harmonic Distortion has long been recognized as a primary concern in power quality, traditionally monitored only through the 51st harmonic. This boundary was sufficient for decades, when most nonlinear loads…
