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 ...

Digital protective relays for power transformers have evolved significantly over the past decades, bringing both reliability and stability in protecting these very expensive and critical assets.

The small, lightweight PTE-50-CE is the ideal instrument to test overcurrent and over/undervoltage protective relays, among many other applications. The reversible 100-VA amplifier can inject up to ...

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 ...

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’ ...

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 ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

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 ...

Omron showcased advanced testing tools for compact electronics, featuring blade pins, relays, and more at DesignCon 2026.
