Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

Advanced power-line monitoring systems combine power-supply monitoring, load-balancing, protection, and metering functions. This allows the power utilities to efficiently deliver grid power while ...

This article has been updated Jan. 18, 2023. The proliferation of affordable and readily available semiconductors in the industrial space has enabled many innovations, making things easier for ...

The Type PFCH capacitor series from Cornell Dubilier Electronics, intended for the ac output of large inverter systems, filter undesirable harmonics before power is delivered to the grid or load. The ...

Even though the function of single phase and three phase relays are quite similar, their applications can vary significantly. This is primarily due to the characteristics of three phase power circuits ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

When India’s first Prime Minister Jawaharlal Nehru visited the planned site of the Bhakra Nangal Dam in Bilaspur in 1954, he called dams “the temples of modern India”. Contained in his turn of phrase ...
