Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Proper selection and effective testing can increase contact reliability in the end product while reducing the overall cost of using relays. Who said relays are pass�? While electromechanical relays ...

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 ...

This new three -phase test instrument addresses the increasing need for three-phase testing capability in electrical distribution substations, renewable power generation stations and industrial ...

This white paper describes Coto's reliability testing of its Coto Classic reed relay and molded reed switches. For many switching applications reed relays remain the best solution, particularly when ...

Relay testing is one of those challenging areas where there never seems to be a shortage of questions. The technology adopted in both the relays themselves and in the equipment used to test them is ...

Distributed generation, also known as embedded generation, is a hot topic at the moment. With more and more generation being connected to the network, those concerned with its stability have to deal ...

Aimed at panel builders, system integrators and process control applications, the HF115FP is available in single and double pole versions, rated at 16A and 8A consecutively. Showing versatility, the ...

Relays can be tiny elements, yet they play vital functions in electrical systems. They operate circuits, guard equipment, and ...

In performing service and troubleshooting on heat pump systems, there are various electrical components to be checked. The following provides information to aid in inspecting and servicing these ...
