Pickering Interfaces (Clacton-on-Sea, UK) has introduced the PI-MXT90-100 test tool that identifies faulty relays on its complex PXI switching matrices. The diagnostic tool uses a test adaptor and a ...

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 ...

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 ...

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 ...

Pickering Interfaces is lowering the cost of ownership of switching systems with the introduction of its eBIRST diagnostic test tools. The eBIRST tools, designed specifically for Pickering Interfaces’ ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...
