Electrical rotating machine repairer DELBA Electrical understands that electrical rotating machines are critical components ...

To help power supply development, semiconductor companies offer evaluation boards which show a typical application of a power-management IC. This gives design engineers the opportunity to start their ...

Branch circuit wiring problems lead to more residential electrical fires than any other single cause. Hidden trouble inside a branch circuit can also lead to electrocutions and the failure of ...

Performance under transient loads has become the most important specification of voltage regulators used to power a wide array of products whose current demands vary quickly during operation. Testing ...

Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

When a circuit is pushed past its limits, it rarely fails politely. It signals trouble through tripped breakers, hot outlets, ...

Testing a Li-ion battery charger using its natural load (i.e., a battery) is time consuming because the charging process can take an hour or more. The test time varies widely, depending on whether you ...

When a technician reported for work shortly before 7 a.m., he picked up exactly where he’d left off the previous day — continuing the task of testing a water-cooled power supply at the unit’s ...

A 240-volt service powers heavy-duty appliances like ovens, air conditioners, water heaters and electric dryers. If something goes wrong in that panel, it may cause those systems to fail, damage the ...

It should come as no surprise that Moore's Law of regularly doubling chip capacity is having an impact on automatic test equipment (ATE) for ICs. ATE, of course, applies patterns of signals and checks ...
