Q. What is the Code rule for sizing short circuit and ground fault protection for a single motor branch circuit? A. The motor branch circuit, short circuit and ground fault protective device must ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

Traditional synchronous boost converters offer little to no protection against short-circuit events at the output. Due to the boost converter’s topology, when the output is shorted to ground, a direct ...

Circuit protection devices are safety components used in a variety of applications, ranging from smartphones and laptops to medical and wireless communications equipment. These components include ...

Siemens Smart Infrastructure launches its first fully electronic starter with semiconductor technology. The SIMATIC ET 200SP e-Starter offers short-circuit protection that is 1000 times faster and is ...

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.
