Some of the most challenging leakage-current-testing requirements are those for patient-monitoring devices—both invasive and noninvasive. Such testing can be time-consuming and expensive, so it is ...

Press the TEST button. You should hear an audible click, the light(s) should go off, and the RESET button will pop out slightly. This means the GFCI is doing its job and responding to a fault. Buttons ...

In a perfect world, all the electrical current sent along a conductive wire would reach its intended destination. However, in the real world some of it is lost along the way for various reasons. Wires ...

Hipot data? That is an oxymoron. A hipot test, also known as dielectric breakdown, is a simple test: Apply high voltage to the insulation barrier of the DUT and ensure there is no breakdown. It is a ...

Fluke announced the availability of its Fluke 368 FC and 369 FC leakage current clamps that help reduce downtime without taking equipment offline. Leakage current can cause unnecessary downtime and ...

PC Series | GFCI/ELCI circuit breakers updated to meet latest UL 943 Standard including self test auto-monitoring and end-of-life indication. Please see GENERAL SPECIFICATIONS section of the datasheet ...

Growing concerns about energy efficiency have led to the development of electronics with higher power density. In grid-connected and industrial applications, such as AC motor control, uninterruptible ...

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 ...
