To be competitive, some electrical contractors often supply low-voltage (LV) service entrance switchboards and switchgear that meet the minimum safety requirements of the National Electrical Code (NEC ...

What is ground-fault protection? The answer depends on whether you are talking about ground-fault protection of equipment or ground-fault protection of people. Just because ground-fault protection is ...

Ground fault protection is a cornerstone in ensuring the safety and operational reliability of modern power systems. Ground faults, which occur when an unintended electrical path connects a live ...

The temporary current in the ground line, caused by a failing electrical component or interference from an external electrical source such as a thunderstorm. See ground. THIS DEFINITION IS FOR ...

California’s wildfire risk has increased in recent years because of climate change, drought, increased development in the wildland-urban interface and the significant buildup of fuel, including on ...

In order to continuously improve the transparency of power distribution grids, it is important to have precise knowledge about the relevant conditions in the local grid. This is achieved by utilizing ...

High-resistance grounding (HRG) makes a power distribution system safer and more reliable than the alternatives. High-rresistance grounding can limit point-of-fault damage, eliminate transient ...

NOTE: THIS SAFETY DEVICE IS STRONGLY RECOMMENDED FOR ALL USERS OF CAPACITOR LIMITED OFF-LINE POWER SUPPLIES! I always wondered what was inside one of these clever devices, so I found one in my junk ...

A pretty typical diagram for the grounding system for a house is shown here, along with a few of the current carrying conductors commonly called live and neutral. On the far left is the transformer ...

A core-balance protection device serves as an example of how these switches operate. Phase and neutral power conductors pass through a toroidal (differential) current transformer. Under normal ...
