We have a number of recognized transmission and distribution experts serving on our board of "Grid Masters." Several times each month we’ll post what we judge to be the toughest questions that also ...

Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

Germany has connected the world’s first supercapacitor-based STATCOM to the grid, with Siemens Energy and transmission system operator TenneT positioning it as a blueprint to replace fossil-fuel ...

American Superconductor Corporation (Nasdaq:AMSC), a leading global supplier of superconductor products and power electronic converters for the electric power industry, today introduced the D-VARâ„¢ ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...
