When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

When designing equipment with switching functions, most engineers find that switching high currents and high voltages is a major problem. A solid-state solution may be possible, but it’s complex and ...

In many electrical installations, general-purpose contactors are used to switch the supply voltage to a small dry-type transformer on and off. One common reason this is done is for area lighting ...
