Circuit protection devices perfect ppt
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

Mux decod pld2_vs2
This document discusses complex integrated circuits used in logic design including multiplexers, decoders, and programmable logic devices. It provides details on 4 categories of integrated circuits based on the number of gates - SSI, MSI, LSI, and VLSI. Multiplexers are described as circuits that select one of several data inputs to connect to the output based on the control inputs. Decoders are the inverse, detecting a particular input and activating the corresponding output. Programmable logic devices can be programmed to provide different logic functions, allowing for changes without rewiring the system.
Electrical Drawings and Schematics
The document discusses the importance of drawings in engineering. It states that drawings are effective communication tools that reduce ambiguity. They are used at various stages of engineering projects from design to construction to operations. The document also outlines standards organizations for drawings and different types of drawings like schematics, technical drawings, and 3D models. It describes best practices for drawing offices, such as maintaining uniformity and using standard symbols and dimensions.
Counters
This document discusses 4-bit up/down counters. It begins by defining a counter as a digital circuit used to count pulses. Counters are implemented using flip-flops and are used for applications like timers. The document then discusses the need for counters to perform counting operations. It provides examples of counters in appliances like microwaves and washing machines that keep track of time. Finally, it covers the different types of 4-bit counters like up counters, down counters, and bidirectional up/down counters along with their state diagrams and truth tables.
LCD interfacing with arduino
Liquid crystal displays (LCDs) use liquid crystals that exist in a state between solid and liquid to control pixels. In an LCD, liquid crystal pixels lie between two glass filters at a 90 degree angle. When electricity is applied, it straightens out the naturally twisted structures of the liquid crystals in the nematic phase, rotating light 90 degrees so it can pass through both filters. This allows the pixels to be switched on and off to display information on the screen.
Digital electronics
Electronic systems can be organized into three basic functions: sense, decide, and act. All digital electronics systems operate using only two states - switching electricity on or off. Computers represent information using binary numbers consisting of 1s and 0s. Logic gates like AND, OR, and NOT are used to perform operations on binary inputs and outputs. Combinational logic circuits use logic gates to create functional outputs solely based on the current inputs. Sum of products and Karnaugh maps are conventional methods to design and optimize combinational logic circuits.

Lesson 1 navigating lab view
Here are a few points of discussion for the group exercise:
- Which Express VIs would you use for each step (acquire, analyze, present)?
- How would you wire them together based on the dataflow?
- What terminals need to be wired to pass the data between steps?
- How can you configure the Express VIs (e.g. time, channels, etc.)?
- How would you save and run the VI to test it works as expected?
The goal is to have the groups discuss and come to a consensus on the basic design using Express VIs before implementing it. Getting the design right first is important.
Floating Point Numbers
Exponential notation can be used to represent very large and very small numbers in a normalized form. A floating point number uses a sign, exponent, and mantissa to represent values in a fixed number of bits. Common standards like IEEE 754 specify single and double precision formats that use 1 sign bit, 8 or 11 exponent bits, and 23 or 52 mantissa bits respectively. Calculations with floating point numbers require aligning the exponents before adding or multiplying the mantissas and adjusting the result exponent.
Plc course level 1

It covers topics like PLC components, programming languages, instructions, applications, installation, and troubleshooting. The target audience includes engineers and maintenance staff interested in PLC automation. Training involves lectures, demonstrations, and hands-on exercises to prepare participants for work with PLC-based systems.
PASSWORD BASED ON/OFF CKT BREAKER
This document describes a password based on/off circuit breaker project. The project uses a microcontroller, keypad, LCD, and relay to allow line workers to safely turn power lines on and off by entering a password. This prevents electrical accidents by ensuring the power is off when workers are repairing lines. The system requires line workers to enter the password at the substation to turn a circuit on or off before working on electrical lines. The project aims to increase safety for line workers through access control and communication between the substation and maintenance staff.
PLc Memory & Addressing
The document discusses PLC memory, including that it consists of the operating system, firmware, and programs and data used by the programmer. It notes that programs can be saved externally but data exchange is too slow for interfacing. Memory includes volatile and non-volatile areas, with volatile memory requiring a battery or capacitor to hold programs and data when power is off. Firmware is stored in non-volatile memory and updated using manufacturer tools. Ladder logic programs are stored in RAM memory and overwrite the previous program when a new one is loaded. Memory capacities in PLCs vary and are expressed in kilobytes or bytes.

BİLGİSAYAR LABORATUARINI KULLANMA KURALLARI
- 1. BİLGİSAYAR LABORATUARINI KULLANMA KURALLARI
- 2. Laboratuara yiyecek ve içecekle girilmez. • Çünkü: Dökülen yiyecek ve içecekler hem laboratuarı kirletir hem de donanımların bozulmasına sebebiyet verir.
- 3. Herkes kendisi için ayrılan bilgisayarda oturmalıdır. Çünkü: Bilgisayar ve internet kullanımı ile ilgili herhangi bir sıkıntı oluştuğunda muhatap olarak kimin alınacağının bilinmesi ancak bununla mümkündür. Böylelikle hiç kimse işlemediği hatanın bedelini ödemek zorunda kalmaz.
- 4. Ders bittikten sonra oturulan sandalyeler düzeltilmeden çıkılmaz. Çünkü: Okul tuvaletleri, laboratuarlar, kütüphaneler gibi ortak kullanım alanlarını kullanılabilir halde bırakmak sosyal bir sorumluluktur. Yeri gelmişken tuvaletleri de temiz kullanıyorsunuz değil mi?
- 5. Dışarıdan getirilen flash disk, hafıza kartı, Cd-Rom gibi depolama araçları öğretmenin izni olmadan kullanılmaz. Çünkü: Depolama araçlarında yer alan virüsler bilgisayarlara zarar verir. Bu disklerin, öğretmen tarafından denetimi yapılmadan kullanılması laboratuarın öğrencilere hizmet sunmasını engeller.
- 6. Fare, klavye, monitör gibi bilgisayar parçaları öğretmenin bilgisi olmadan sökülemez, bilgisayarlar arasında yer değiştirilemez. Çünkü: Bilgisayar parçaları hassastırlar ve bilgisizlikten kaynaklı hatalar bilgisayarı yahut ilgili donanım parçalarını kullanılamaz hale getirir.
- 7. Öğretmen bilgisayarı, öğretmenin izni olmadan kullanılamaz. Çünkü: Öğretmen o sınıfın yöneticisidir ve dersle ilgili her işlem öğretmen bilgisayarı üzerinden gerçekleştirilir. Öğrenci tarafından kullanılması bilgisayara zarar verebileceği gibi, öğretmene saygı açısından da uygun değildir.
- 8. Bilgisayarlar güç düğmesinden değil, “başlat/ bilgisayarı kapat” komutu ile kapatılır. • Çünkü: Bilgisayarı, power (güç) düğmesine basarak kapatmak, bilgisayar için ani elektrik kesintisi demektir ve bilgisayara zarar verir.
- 9. Öğretmenin izni alınmadan ayağa kalkılmaz, gezilmez. • Çünkü: Etkin bir ders; ancak ders düzeninin sağlanması ile yapılabilir. Herkesin kafasına göre hareket ettiği bir ortamda düzenden ve verimlilikten söz edilemez.
- 10. Bilgisayarlara messenger, oyun gibi programlar yüklenmez. • Çünkü: Bilgisayar dersi sohbet edebilmeniz, boş yere vakit geçirmeniz için bir eğlence aracı değil, bilgi çağına ayak uydurabilmeniz için sunulmuş bir güzelliktir.
- 11. Hayatımızın her evresinde kurallar silsilesi ile karşılaşırız: görgü kuralları, okul kuralları, trafik kuralları, sınıf kuralları… Kurallar çoğu zaman sıkıcı gelir: ancak bunlara uygun olarak hareket etmek bir yük değil, kaliteli bir yaşam için gereklilik olarak görülmelidir. Gerekenler okunduğuna göre: şimdi ise sırada bir temenni: ADAB İLE KALINIZ!
