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 ...

Interface relays connect computers and PLC logic devices to machines. But conventional block, modular terminal strips, and socket I/O relays are difficult to modify, and require hours of downtime 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 ...

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 ...

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 ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...

Many of the electrical power networks have seen significant changes over the last few years. Due to the change in energy policy, today’s power is fed into these grids at many different points while ...

Megger’s new SMRT 36 smart protective relay test set is suited not only for testing today’s installations and legacy plant, but also for meeting the future challenges associated with testing the smart ...
