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 ...

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 ...

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 ...

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 ...

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 ...

Testing verifies that protection schemes meet their intended purpose, ensuring safety and system integrity. Function testing involves manual or electrical manipulation of components to confirm signal ...
