GE Digital Energy has announced the Multilin L30 Line Differential System, which delivers cost-effective current differential protection for high-speed, sub-transmission and distribution lines and ...

GE Digital Energy has signed a 10-year strategic agreement to supply the Tennessee Valley Authority (TVA; Knoxville, Tennessee, U.S.) with Multilin Universal Relay (UR) products for its existing and ...

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

Here’s an interesting introduction to Reed Relays, Mercury Displacement Relays, Contactors, Polar Relays, Latching Relays, T-Bar Relays, Time Delay Relays, and Stepping Relays. Here’s an interesting ...

Although many electromechanical relays have been replaced by their solid-state cousins, they still have their place in electronic systems and they are still being manufactured. The early telephone ...

The cost of component failures continues to increase as electronic products become more complex. Most component replacement costs are associated with marginal devices that become intermittent or fail ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

Since the introduction of solid-state relays some decades ago, the debate over which is better, solid-state relays (SSRs) or electromechanical relays (EMRs), has gone on. The general answer is neither ...
