The new tests include a D.C. valve-voltmeter circuit for core-to-sheath insulation faults, audio-frequency search methods for open circuits and radio-frequency tests for conductor defects.

Electrical insulation faults are a significant contributor to the failure of rotating machines. Industry studies described in the next chapter indicate that up to one-third of rotating machine ...

Renovations for concrete can cost what feels like a mini fortune. But this foam material can fix those concrete problems at a ...

The test uses a low level of excitation to detect faults in the stator core’s interlaminar insulation. GE Vernova also has a generator retaining ring scanner, which is a robotic inspection tool ...

When a lateral displacement takes place on a fracture, the break is referred to as a fault. Earthquakes are associated with displacements on faults. In this lesson, students learn about the ...

When a ground fault occurs, electric current may find a path to ground via dust, water, or worn insulation. Most short circuits in electrical equipment are caused by ground faults, which can also ...

Poorly installed spray foam insulation can cause structural safety problems. By blocking ventilation, spray foam can result in severe condensation in the roof space. This can lead to rot in the roof ...

If you’re living in a home that has no insulation in the attic, don’t let another summer approach without fixing the issue. Consult our guide to determine the average cost to insulate an attic ...

She is based in Encinitas, California. Roof insulation can reduce energy costs by up to 20% and improve home comfort. Common insulation types include spray foam, fiberglass batts and rigid boards.

Earthquakes happen every day all over the world, along both tectonic plate edges and interiors. Earthquakes occur along faults, which are fractures between blocks of rock that allow the blocks to move ...

Determining the cause of a problem. Also known as "fault diagnosis," the term may refer to hardware or software, but always deals with methods that can isolate the component, device or software ...
