With the exception of the incandescent light bulb, every load today creates harmonics. Unfortunately, these loads vary with respect to their amount of harmonic content and response to problems caused by harmonics.
Consider all site parameters before recommending an IG system. But first, measure existing equipment grounding system's impedance with a ground impedance tester prior to making any changes to the grounding system.
With today's technology, power quality students have many choices. And as more electrical contractors strive to keep up with that technology, many new training methods become viable alternatives to costly classroom instruction.
Here are five key revisions to this IEEE standard, some of which are in response to manufacturer and end user concerns. The upcoming version demonstrates that its working group is able to stay current in the ever-changing power quality field.
Finding voltage quality problems is a lot like detective work. You rely on the power line monitor to gather evidence of any unseen disturbances. But, how can you ensure a safe monitor hookup and meaningful captured data?
Proper bonding and grounding of communication systems provide reliable operation for voice/data equipment, while enhancing safety for the operator in the event of lightning and AC ground fault conditions. Using ANSI/EIA/TIA-607 grounding topologies, you can achieve these objectives.
