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.
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
This paper presents the case for discussion on the advantages and disadvantages of each method for generator grounding. Medium Voltage Generators are not designed to withstand full fault current during a single phase to ground fault. This is the main reason that medium voltage generators are connected to a system with either low or high impedances. There are many methods to ground generators. To find out what these methods are, please download this free whitepaper....More
