Alternating current (AC) electrical power has been used in industrial facilities and in people’s homes since 1882. Over the years, we have come to recognize the hazards associated with AC, and safety ...

The digital voltmeter is the best basic tool for electrical troubleshooting, because it's calibrated and exact. But remember, the digital voltmeter can't detect a high-resistance fault if the circuit ...

Bill Nyquist needed a little extra heat and air conditioning for a guest room above the garage at his Mendham home. He purchased an LG mini-split heating and cooling unit seven years ago but it ...

Flammable insulating fluids and electrical faults pose significant fire and explosion risks to transformers. These hazards can result in catastrophic damage, disrupt business continuity, and cause ...

American utilities operate on an integrated power grid of more than 200,000 miles of high-voltage transmission lines. To distribute electricity through this system requires transmitting voltage at ...

The comparison figure between no arc-fault state and arc-fault state under various type of loads, ranging from 30 W–60 W. An arc fault is an electrical discharge between two conductors due to poor ...

High-voltage power transmission systems are more important today than ever before because power generated at renewable energy sites in remote locations must often be transmitted to distant load ...
