The mains of the world were constructed as a giant copper causeway to transport electricity from the generating station to our homes and factories. Today's problems on the mains were unknown a few ...

Though critical to the nation’s power grid, large power transformers are some of the most vulnerable components in the system. Armed with a shared determination for resiliency, government, industry, ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management. Understanding the trade-offs between Delta and Wye connections enables ...

Follow these basic steps to select the best transformer for each phase of your next project. Suppose you've got the job of designing the power distribution for an entire building. At some point, ...

Madhubani: Amid soaring temperature, Madhubani urban area is grappling with frequent power outages due to overloading and transformer failures and thus forcing the residents to suffer during the ...

Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

Eskom has blamed the need for load reduction on the high number of non-paying customers who put immense strain on the power grid. “Most transformers that are overloading have 80% of customers not ...
