of charge carriers reverses direction periodically. The number of complete AC cycles per second is the frequency‚ which is measured in hertz. An example of pure DC is the current produced by an electrochemical cell. The output of a power-supply rectifier‚ prior to filtering‚ is an example of pulsating DC. The output of common utility outlets is AC. Current per unit cross-sectional area is known as current density. It is expressed in amperes per square meter‚ amperes per square centimeter‚ or amperes

ABSTRACT This document describes the experimental process of developing a non-mechanical hot plate wind and rain sensor. It aims to discuss practical aspects of the necessary hardware to fulfil such a function and different software approaches to controlling such a system. Specifically‚ it discusses an experiment based on 30W hot plates controlled by Labview in an attempt to measure changing wind and rain conditions. It also looks at the data gathered in this instance and calibration

Automatic Street Light [pic] Submitted By: Introduction Automatic Streetlight needs no manual operation for switching ON and OFF when there is need of light. It detects itself weather there is need for light or not. When darkness rises to a certain value then automatically streetlight is switched ON and when there is other source of light i.e. day time‚ the street light gets OFF. The sensitiveness of the street light canal so be adjusted

Konèar PowerTransformers Ltd. A Joint Venture of Siemens and Konèar STRAY LOSSES HOW TO REDUCE THEM AND WHY? KPT-OIPT 013E‚ Published 02.2000. Generally‚ there is a simplified understanding that the socalled load losses in a transformer (load losses‚ PL ) depend on the ohmic resistance of the windings. This is only partly true‚ as the losses arising from magnetic leakage flux in various metal parts of a transformer constitute a significant part of the total losses. This component

Operation and Control of Auxiliary Systems: FUEL/GBC: Safe operation of GBC Check out while starting: • CW System: Ensure that the cooling water pump & at least 04/05 nos fan are in running condition. • Seal Gas Skid: Always Charge gas through gas filters GT-F8102 and fill the system. This prevents dirty gas going to seals. • Always maintain barrier seal pressure @ 0.3to 0.5 atg on OTB side and TB side before start of the Lube oil Pump and during normal operation.
