Current Overloading

One important issue concerning fire prevention is the early detection of overheated wire insulation, a common source of smoldering fires. Therefore model experiments were performed to examine how far early indications of overheated insulation could be recognized by the gradient microarray and its simple sampling arrangement. The tests were carried out in a closed box with KAMINA placed next to a cable overheated by a current overload. The experiments were performed... 

Unless one really needs the large cathode area of the end-on tubes (and for this problem lenses were created), we find that an excellent tube like the Hamamatsu 928 (Hamamatsu Corp., 420 South Ave., Middlesex, N.J. 08846) to be an extremely versatile performer. This PM has a very broad spectral response from 200 nm to 900 nm, exhibits little if any hysteresis, and can tolerate gross current overloads. A new development has been a miniature PM by Hamamatsu (R1635) that has a risetime of 800 psec. However, since it is an end-on design at present it has limited anode current capability and insufficient red response for many applications.

Starting devices, locally and remotely mounted to limit current overloads on power equipment, are standard installation. Manual or power... 

About one-quarter of the part failures in electronic equipment are capacitor failures. One-half of these failures are caused by improper selection and application. Some typical causes of capacitor failure are (1) voltage overload, (2) current overload, (3) high temperature, (4) frequency effects, (5) shock and vibration,... 

The body-current overload protection should actuate if the magnetic field is reduced for any reason. RF Circuits... 

A fuse will provide protection against faults and continuous marginal current overloads. It is basically a thin strip of conducting wire which will melt when the rated...
