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 ...

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 ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

IEC 61850 is the new international communication standard for substations. The main goal of 61850 is to obtain interoperability between different protective devices from different vendors. IEC 61850 ...

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 ...

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 ...
