use of bjt in aircraft Typical applications for transistors in aircraft electrical and electronic systems are controlling generator field current, driving lights and warning displays, amplifying signals from sensors and transducers and for use as amplifying devices in cabin interphone and aircraft radio and navigation aids. Conventional bipolar junction transistors ( BJT ) generally comprise […]
power saving system
Automated Intelligent Power Saving System and Security free download 1 a power saving device. The transistor turns ON which switches the relay and it turns on the fan and light and other electrical appliances connected to it. When the person leaves from that area, the PIR sensor activates again and the corresponding security surveillance or […]
RECYCLING OF 3D FILAMENT
recycle 3d filaments Turn your 3D printed waste into new spools using a 3D printer filament recycler. The typical recycler will smash failed prints into smaller pieces, melt them down, and force the liquid plastic through an opening. The hot plastic is then cooled down and coiled onto a reel. The two most commonly used […]
3D PRINTING FILAMENT
3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties, requiring different temperatures to print. the most common filament types are acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA). Most basic 3D printers are designed to exclusively use these filaments. Fused- filament […]
grid connected power generation method
A grid-connected photovoltaic system, or grid-connected PV system is an electricity generating solar PV power system that is connected to the utility grid. A grid-connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment. In wind power generation system the grid connected inverter is an important […]
electrical machine 2020
The electric machines are of three main types, transformer, generator, and motor. Electrical Transformer: In the transformer, both input and output are electrical An electrical machine is a device which converts mechanical energy into electrical energy or vice versa. Electrical machines also include transformers, which do not actually make conversion between mechanical and electrical form […]
Transmission line fault detection
Transmission line fault detection phase selection using ANNfree downloadA novel application of neural network approach to protection of transmission line is demonstrated in this paper. Different system faults on a protected transmission line should be detected and classified rapidly and correctly. This paper presents the use of neural Transmission line fault detection and classification using […]
Active Distribution Networks
Active distribution network will be able to highly integrate and utilize a variety of distributed energy through real-time control system and two-way communication network to improve system reliability and operational efficiency. Active distribution network concept is capable of real-time monitoring of whole grid and it may utilize the flexibility of distributed energy resources to enhance […]
four quadrant dc motor control technology
High performance motor drives are necessary parts of industrial applications. A motor drive system with high performance has special characteristics such as good dynamic speed command tracking and load regulating response. The methods of control are much simpler and less expensive than those of alternating current motors. Modelling and simulation of four quadrant operation of […]
