In an earlier article, I covered Fire Hazard Tests that form an important part of safety testing for electronic/electrical products. We looked at the standards and equipment used for abnormal heat, ...

Detection of uncontrolled electricity along city streets and sidewalks is a concern for many municipalities and utilities. The preferred method of identifying these locations is to seek out these ...

For over a decade, thousands of users have deployed Permanent Electrical Safety Devices (PESDs) in order to reduce their risks in isolating electrical energy. This innovation greatly reduces the ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

The street scene shows damage caused by an explosion in a manhole as a result of gases generated by a low-voltage arcing fault. North America, according to statistics published by the IEEE Insulated ...

Poor power supply quality—in the form of dips, dropouts, and other voltage variations—can result in electrical malfunctions that can have serious consequences. To verify that automotive systems will ...

Probing to test voltage in electrical connectors on farm equipment can be a challenge. Here are some tricks: A straightened paper clip fits the sockets on many electrical connectors. It’s easier to ...

Voltage requirements are increasing, especially for the EV market. Even devices that might be considered relatively low voltage, such as display drivers, are now pushing past established baselines.

Makers of programmable power supplies and loads have been busy on a variety of fronts. They have focused on minimizing ripple and distortion, cutting weight and cost, improving usability and interface ...
