Manufaturing transformer
This document summarizes the manufacturing process and maintenance of power transformers. It describes the key components of a transformer like the core, windings, bushings, oil filling, and conservator. The manufacturing process involves preparing the raw materials, winding the coils, assembling the core and coils, connecting accessories, drying, oil filtration and filling. Regular maintenance is needed to monitor the transformer hourly, daily, weekly, monthly, yearly and every 2-5 years to ensure proper functioning. Transformers are important equipment that allow transmitted power to be stepped up or down to usable voltages without changing frequency.

PRESENTATION ON MANUFACTURING OF TRANSFORMER By Dhruv Jimit
THIS PRESENTATION WILL GIVE A GREAT KNOWLEDGE OF MANUFACTURING OF PRACTICAL AS WELL AS THEORETICAL TRANSFORMERS.
Testing of transformer
This document discusses testing of transformers. It provides an overview of transformers and their functions in transmission and distribution of electrical energy. It then describes various routine, type, and special tests performed on transformers, including winding resistance measurement, voltage ratio measurement, no-load loss measurement, load loss measurement, insulation resistance measurement, and dielectric tests. It also discusses short-circuit testing procedures and criteria. Temperature rise testing and its limits are also summarized.
Poles and towers
Electrical energy is generated at power stations and transmitted through a network with two parts: transmission and distribution. The transmission system uses high voltage power lines supported by steel transmission towers ranging from 15-55 meters tall. There are different types of poles that can support power lines for the distribution system, including wooden poles, concrete poles, steel tubular poles, and steel towers, with factors like cost, strength, and maintenance considered for the appropriate selection. Safety protocols must be followed when working with transmission towers.
Underground cables
This document discusses underground cables for electrical power distribution. It covers the construction of cables including conductors, insulation, metallic sheathing, bedding, armouring and serving. Common insulating materials like XLPE are described. Cables are classified based on voltage level. Methods of laying cables underground include direct laying, draw-in systems and solid systems. Potential cable faults include open circuits, short circuits and earth faults. Underground cables have advantages over overhead systems like better appearance, lower maintenance needs and fewer faults, but the installation costs are higher.

Aim of conduction transformer Open Circuit & Short Circuit test
To predict its performance without actual loading.
Determination of equivalent circuit parameters
To determine parameters of a transformer like voltage regulation and efficiency
Open circuit test is carried out to determine core loss and shunt parameters.
Open circuit test is carried out at rated voltage and rated frequency . During this test, rated flux is produced in the core .
To carry out open circuit test rated voltage at rated frequency is applied to LV side of the transformer and HV side is left opened as shown in the circuit diagram.
HV side is left opened because it is easier to arrange rated voltage supply on LV side because no load current which is quite small about 2 to 5% of the rated current.
Metering instrument connected at LV side are economical & always safer to work.
The voltmeter, ammeter and the wattmeter readings are taken and suppose they are Voc , Io and Poc respectively.
Strictly speaking the wattmeter will record the core loss as well as the LV winding copper loss. But the winding copper loss is very small compared to the core loss as the flux in the core is rated.
Transformer - Detailed Presentation 50 slids
1. Transformers have on-load and off-load tap changers that allow adjusting the transformer's output voltage without interrupting the load current. On-load tap changers can adjust voltage while energized using fast-acting switches, while off-load tap changers require de-energizing the transformer to change taps.
2. On-load tap changers are commonly used in power generation and distribution transformers to control voltage as load and line conditions vary. They monitor voltage and raise or lower taps using an automatic voltage regulator. Off-load tap changers are typically used in solar and wind projects where the generator voltage is low-voltage.
3. The on-load tap changer maintains uninterrupted
Reluctance and inductance
Reluctance is the opposition to magnetic flux in a magnetic circuit, analogous to resistance in an electric circuit. Reluctance is caused by properties of the magnetic material like length, cross-sectional area, and permeability. The reluctance of a non-uniform magnetic circuit is calculated by adding the reluctances of each uniform section. An air gap is often included to reduce saturation by increasing reluctance.
Inductance is the ability of a circuit to store energy in a magnetic field. It is caused by the self-inductance within a coil or mutual inductance between two linked coils. Inductors use this property to oppose changes in current flow. The standard unit for inductance is the henry.
Hvdc technology
HVDC systems remain the best option for long-distance bulk power transmission and connecting asynchronous grids. They allow for more economical and environmentally friendly power transmission compared to HVAC systems in these conventional applications. However, advances in technology, deregulation of electricity markets, and environmental protection efforts are increasing the viability of HVDC systems for additional situations where high voltage AC transmission was previously preferred.
Transformer, Electromagnetic WavesTheory
This document provides information about transformers and their components. It discusses how transformers work using electromagnetic induction to transfer energy between circuits without a direct electrical connection. The key components of a transformer are described, including the magnetic core made of silicon steel, the windings, insulation and cooling using mineral oil. Ideal transformer theory is also covered, explaining voltage and current ratios based on winding turns.
Lightning protection of windmill
The document discusses lightning protection for wind turbine blades. It defines a wind turbine as a device that converts wind's kinetic energy to electrical power. There are two main types: horizontal axis and vertical axis turbines. Lightning is a sudden electrostatic discharge during a storm that can generate direct thermal effects at the strike point. The blades are one of the most vulnerable parts and research has analyzed the damage mechanisms from lightning strikes. Installation of lightning arresters at blade tips can effectively intercept lightning strikes.
Case Study - Importance of Relay Coordination in Process Industries
A cement plant experienced unexpected tripping of the entire plant twice in three months due to poor relay coordination. An investigation found that load had been added to a motor control center without properly adjusting the relay settings. Specifically, a 75kW high pressure pump and compressor loads totaling 217kW were added. This caused the starting current of a 315kW crusher motor to exceed threshold levels after it restarted, tripping the entire plant. The outages cost the plant over 500 tons of lost cement production and 2.5-2.8 million rupees in losses each time. The case study highlights the importance of coordinating relay and protection settings whenever modifications are made to the electrical distribution system.
INSULATORS & TYPES
Main component parts of the overhead line
The most effective method of providing protection to transmission lines against direct lightning strokes is by use of overhead ground wires as shown in Fig 6. For simplicity, one ground wire and one line conductor are shown. The ground wires are placed above the line conductors at such positions that practically all lightning strokes are intercepted by them (i.
e. ground wires). The ground wires are grounded at each tower or pole through a low resistance as possible. Due to their proper location, the ground wires will take up all the lightning strokes instead of allowing them to line conductors. The degree of protection provided by the ground wires depends upon the footing resistance of the tower.
PPT Fault Analysis
This power point presentation provides an overview of fault analysis and sequence networks in power systems. It defines different types of faults including open circuit faults, short circuit faults, symmetrical faults, and unsymmetrical faults. Symmetrical faults involve all three phases and remain balanced, while unsymmetrical faults involve one or two phases. Sequence networks, including positive, negative, and zero sequence networks are used for fault analysis. The presentation describes each type of fault and sequence network in detail.
Sample calculation-for-differential-relays
The document provides calculations for setting differential relays on a power transformer. It includes calculations of currents at different transformer taps to determine relay settings that avoid unwanted operation during tap changes. Currents are calculated for the high voltage side, low voltage side and on the relay at extremes of +/- 10% taps. The differential current at each tap is compared to the relay operating current to set the pickup value to avoid operation during tap changes while maintaining protection.
Automatic voltage regulator(avr)
The document is a product brochure for TVR-Line voltage regulators manufactured by Zhejiang Farady Electric Co., Ltd. It summarizes the company profile and provides details on the voltage regulators' applications, working principles, technical specifications, structure, functions, installation examples, and answers to frequently asked questions. The voltage regulators can automatically adjust output voltage to keep it stable within ±10-30% of the rated voltage and improve power quality and supply reliability for distribution lines.
132kv substation inplant training seminar
This document provides an overview of the key components in a 132kV substation, including:

- Coupling capacitors that allow communication over power lines.
- Wave traps that offer low impedance to carrier frequencies for communication.
- Current and potential transformers that reduce currents and voltages for safe measurement and protection.
- Circuit breakers, transformers, and busbars that distribute power throughout the substation.

LV SWITCHGEAR -Final PPT.pptx
This document discusses low voltage switchgear, including definitions and examples. It describes common types of low voltage switchgear like air circuit breakers, MCCBs, contactors, relays, and fuses. It provides information on their ratings and standards. The document focuses on contactors, explaining their operation, applications, selection parameters, and utilization categories. It also discusses motor protection concepts and thermal overload relays, including their operation and selection parameters.
Selection of transmission voltage
There is an optimal transmission voltage for electricity that balances various transmission costs. While increasing voltage reduces the cost of conductors, it also increases the costs of insulating equipment, transformers, and support structures. The document discusses how transmission voltage, power transmitted, and transmission line length affect the economic transmission voltage. A graph of total transmission cost versus voltage shows the minimum point as the optimal voltage.
Transformer 2
This document discusses five types of transformer testing: open circuit testing, short circuit testing, load testing of single phase transformers, Sumpner's testing, and polarity testing. Open circuit testing determines losses with one winding open. Short circuit testing determines copper losses at full load. Load testing determines efficiency and regulation characteristics. Sumpner's testing uses two identical transformers to determine iron and copper losses. Polarity testing determines if the transformer windings produce voltages that are additive or subtractive.

Integracion de las tic en las
El documento habla sobre la integración de las TIC en las teorías de aprendizaje de Bruner y Piaget. Según Bruner, el aprendizaje por descubrimiento favorece el desarrollo mental ya que es importante que los estudiantes resuelvan problemas por sí mismos. Los profesores deben proporcionar situaciones problemáticas y recursos como software educativos y blogs para estimular el aprendizaje. Por su parte, Piaget explica que el aprendizaje se da a través de la asimilación y acomodación a través de

CDPQ Infra dévoile un plan de mobilité de 15 G$ sur 15 ans pour la région de Québec. Une alternative plus économique et rapide, ne serait-elle pas posssible?
- Valoriser les infrastructures ferroviaires du CN, en créant un Réseau Express Métropolitain (REM) plutôt qu'un nouveau tramway ou une combinaison des 2.
- Optimiser l'utilisation des rails pour un transport combiné des marchandises et des personnes, en accordant une priorité aux déplacements des personnes aux heures de pointes.
- Intégrer un téléphérique transrives comme 3ème lien urbain dédiés aux piétons et cyclistes avec correspondance avec le REM.
- Le 3 ème lien routier est repensé en intégrant un tunnel routier qui se prolonge avec le nouveau pont de l'Île d'Orléans et quelques réaménagemet de ses chausées.

CDPQ Infra unveils a $15 billion, 15-year mobility plan for the Quebec region. Wouldn't a more economical and faster alternative be possible?
Leverage CN's railway infrastructure by creating a Metropolitan Express Network (REM) instead of a new tramway or a combination of both.
Optimize the use of rails for combined freight and passenger transport, giving priority to passenger travel during peak hours.
Integrate a cross-river cable car as a third urban link dedicated to pedestrians and cyclists, with connections to the REM.
Rethink the third road link by integrating a road tunnel that extends with the new Île d'Orléans bridge and some reconfiguration of its lanes.
