Oxidation in IC Fabrication: Oxidation in IC Fabrication is very important process. In one line, oxidation can be explained as the production of SiO2 using the thermal growth technique. Some of the important uses of…
Overload Protection Relay: Overload Protection Relay - Continuous balanced overloading of a machine causes overheating in the stator winding. An obvious solution to this is the application of overcurrent relays; but this is not usually…
Overlapping Zones of Protection: Overlapping Zones of Protection - In order to provide selectivity to the system it is usual practice to divide the entire system into several protection zones. When a fault occurs in…
Overhead vs Underground System: The distribution system can be Overhead vs Underground System. Overhead lines are generally mounted on wooden, concrete or steel poles which are arranged to carry distribution transformers in addition to the…
Overhead Line Insulators Interview Questions and Answers: 1. What are the important properties that an overhead line insulator must possess ? Ans. The most important properties that an overhead line insulator must possess are :…
Overhead Equipment in Electric Traction Systems: Simplest type of overhead equipment in electric traction systems consists of a single contact wire supported either by bracket or by overhead span. The maximum distance between two consecutive…
Overhead Construction for Tramways, Trolley Buses and Railways: As we know already that, for trams, trolley buses and for railways operating at 1,500 V and above overhead contact wire is used. The design of overhead…
Overfeed Stoker and Underfeed Stoker - Definition and Types: There are two common methods used for burning coal. 1. Stoker firing 2. Pulverised fuel firing. The stoker firing method is used for firing solid coal…
Overcurrent Relay Characteristics: The operating time of all Overcurrent Relay Characteristics tends to become asymptotic to a definite minimum value with increase in the value of current. This is inherent in electromagnetic relays due to…
Overcurrent Protection Relay in Power System: The technique of Overcurrent Protection Relay in Power System is still widely used as a means of detecting faults on distribution system and on transmission lines fed from one…
