Misfits of Design

What are they thinking when they installed this electric post in the middle of the road? Is there a way to future proof this design? How could they ever know …

Harmonics and Power Quality

An ideal power quality for a source of energy to an electrical load is represented by a pure sine wave waveform of voltage. The term pure means that it does …

Phase Sequence of Harmonics

Harmonics of different orders have different phase sequences. What is phase sequence any way? In simple terms, a phase sequence is the order of rotation of phase vectors relative to …
