POLYFUSE

INTRODUCTION
Current flow in a conductor always generates heat. Excess heat is damaging to electrical components. Overcurrent protection devices are used to protect conductors from excessive current flow. Thus protective devices are designed to keep the flow of current in a circuit at a safe level to prevent the circuit conductors from overheating.
A fuse is a one-time over-current protection device employing a fusible page link that ....etc

High-voltage fuse blower indicator with voice-based announcement system is a type of circuit used to alert the user in the event of a fuse in any electrical equipment being fused. The technology used in electrical equipment has been developed in a wide range. At the same time it is necessary to use the systems with automation and high security. This article shows the study of fuses, the types of faults that occur in a system, and to detect if a fuse has blown out of the circuit with the help of power sensors, micro-controller LEDs and voice ann ....etc

abstract of substation fuse blow indicator

This is a Blown Fuse indicator by LED Display. A Fuse be the equipment protects that use often most. Because of cheapness can use protect electronics expensive circuit. Generally when fuse torn us can know immediately. but in sometimes Fuse torn already we don t know. such as in electricity automobile system brake system , the system delays the electric current very much, etc. Fuse torn get into trouble at we must know for immediately the safety.

So I would suggest this circuit is simple. It can sho ....etc

Polyfuses is a new standard for circuit protection. It is re-settable by itself. Many manufactures also call it as Polyswitch or Multifuse. Polyfuses are not fuses but Polymeric Positive temperature Coefficient Thermistors (PPTC). We can use several circuit protection schemes in 'power supplies to provide protection against fault condition and the resultant and over temperature damage. Current can be accomplished by using resistors, fuses, switches, circuit breakers or positive temperature coefficient devices.Resistors are rarely an acceptable ....etc
