Like peeling away the layers of an onion, research into electrical injuries is revealing more all the time. It’s enough to bring a tear to the eye when the full extent of the potential damage to unfortunate victims — most from the workplace — is completely grasped.
Now soaking wet, the “elephant in the room” is perhaps easier to see. With its floodwaters swamping generators, switchgear, and fueling components for backup power systems serving scores of facilities in and around New York City in October 2012, Hurricane Sandy exposed a flaw in backup power that now may be too big to ignore.
Thermal imaging technology that flags possible electrical problems before they fully form and wreak havoc clearly demonstrates that heat generates light. But if light is also defined as the unvarnished truth, that may only be accurate in the purely physical sense.
For an energy source that’s so consistent and measured in its 93-million-mile trek to Earth’s atmosphere, solar power rides a roller coaster of heady promise and stark reality as it’s factored into the market for electrical energy.
Injuries to workers exposed to high voltage and related electrical hazards may never be totally eliminated, but it won’t be for any lack of trying to bolster the NFPA 70E workplace electrical safety standard.
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
