Complete Guide to General Electrical Knowledge
High voltage allows electric power to move long distances with lower current and lower conductor losses, but it also increases insulation, clearance, protection and safety requirements. This guide explains what voltage…
Power Distribution System Design: Planning & Engineering Guide
An electrical distribution system transfers power from a utility connection or generator through substations, transformers, switchgear, panels and cables to the final loads. Good design delivers acceptable voltage,…
Complete Guide to Electrical Calculations & Conversions
Converting kVA to amps is one of the most common calculations in transformer, generator, cable and switchgear selection. The arithmetic is simple, but the result is only correct when the phase arrangement and voltage…
Power Factor Correction Capacitor: Guide
A power factor correction capacitor supplies reactive power close to an inductive load, reducing the reactive current drawn from the utility. Correctly applied, a capacitor bank can lower current, release transformer…
