Overcurrent protection of conductors is an idea so simple that it is almost self-evident. Excessive current in a conductor results in rapid temperature rise, which damages insulation and creates ...

One of the most common reasons to measure current in today’s automotive systems is to detect fault conditions and respond to them quickly. I touched on this topic previously in Signal Chain Basics ...

In this EC&M Tech Talk Randy Barnett discusses in five different sections the concepts and rules of overcurrent protection. Overcurrent protective devices include the fuses and circuit breakers ...

Book Abstract: An overcurrent is caused by a short-circuit, ground-fault, or an overload. A short-circuit may be hundreds or even thousands of times above the normal operating current. This type of ...

Today's preferred rechargeable battery chemistry for small, lightweight, portable applications is lithium-ion. When it comes to power management for mobile phones, portable media players or navigation ...

Abstract: Paralleled power systems require a hot swap which indicates the replacement of a converter module without shutting down the whole system for easy ...

Synchronous buck regulators are widely used in industrial and infrastructure applications to step down 12V rails to point-of-load inputs as low as 0.6V for microcontrollers, FPGAs, memory and ...

We designed and implemented a Definite Time Lag (DTL) overcurrent relay system with load shedding capabilities. This project demonstrates practical application of power systems protection principles.

A new feature introduced in the AVR® DB family is the Analog Signal Conditioning (OPAMP) peripheral. In this example, the OPAMP is used together with an Analog Comparator (AC) to form a current spike ...

The proposed relay consists of one current and one voltage transducer, as well as two passive elements: 1) an inductor; and 2) a capacitor. For bolted and relatively low-resistance faults, the relay ...
