480 Voltage Power and Current Formula for single-phase and three-phase circuits: compute kW, amps, and power factor from 480 V line voltage using P=V*I*pf and P=sqrt(3)*V*I*pf for balanced loads ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

A phase to phase connection links two live wires in a multi-phase system, delivering higher voltage than a phase to neutral setup. It's common in industrial power distribution for running heavy ...

Abstract: Most of the loads in industrial power distribution systems are balanced and connected to three power systems. However, voltage unbalance is generated at the user's 3-phase 4-wire ...

In this article, Jake Green, Head of Technical Engagement, Scolmore Group, considers where three-phase supplies come from and some of the general terms used. In subsequent articles Jake will consider ...
