DC motors may not be the wave of the future, but they certainly have a secure place in today’s workplace. Therefore, it’s worthwhile for electrical professionals to take a look at their inner workings and, when the time comes, be prepared to service DC motors.
Many electricians have broadened their work model in recent years to include coaxial and Ethernet wiring for communications and data networks. This is usually seen as a good move, given the fact that additional revenue streams become available without excessive overhead or investment during uncertain economic times.
Overcurrent devices provide an essential level of protection in residential, commercial, and industrial applications. Flawless functionality, however, is dependent upon correct design and installation.
Proper grounding and bonding prevent unwanted voltage on non-current-carrying metal objects, such as tool and appliance casings, raceways, and enclosures, as well as facilitate the correct operation of overcurrent devices.
For decades, versatility and potential cost savings have spurred the use of medium voltage variable frequency drives (VFDs) in a wide range of applications. From pipelines with fluctuating flows to mine conveyors with variable throughput,...More
Testing for earth ground resistance is essential for two important reasons: safety and equipment uptime. Without an effective grounding system, fault currents have no safe path to ground, and those current will find unintended paths that could include people. Poor grounding is also a cause of poor power quality....More
