The reliability of an electrical network model is similar to the strength of a chain: Both vary as a function of their weakest links. Beyond their enabling a utility to rapidly respond to the exact ...

Among the various diagnostic methods used to assess transformer condition, capacitance and Tan Delta testing has gained broad acceptance as an effective means of evaluating insulation health. By ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

International technical platforms such as the IEEE PES Transmission & Distribution Conference and Exposition play a key role in shaping these developments by bringing together grid operators, ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.
