Smaller, lighter and with a higher output power than any other comparable single-phase protective relay test instrument, Megger’s new SMRT1 smart protective relay test set is suited not only for ...

Testing relays is both an art and a science. As relay technicians inevitably learn in the field, pure theory-based understanding of protective relays is not nearly enough for the real-world situations ...

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

This AC power switch circuit senses the presence of AC current in one outlet of a multi-outlet power strip and switches power to the remaining outlet(s). It utilizes a current transformer, single ...

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...

In part 1 of this two-part series, I addressed the mixed-signal-test challenges presented by the fact that automatic test equipment's AC instrument channel density has not increased at the same rate ...
