Transmission network operators are facing substantial and even contradictory challenges. A highly variable renewable energy supply and an increased focus on energy efficiency require a reinforcement of the grid, but the resistance against the construction of new lines has never been so high. The new generation of copper alloy conductors can be part of the solution. These copper alloys offer outstanding mechanical properties and a high annealing temperature that makes possible to apply affordable and durable hydrophobic coatings. This unique combination makes the new copper conductors highly suitable for severe weather conditions (wind & cold) both in new lines and in refurbishment projects. Additionally, the high conductivity of copper offers a significant reduction of life cycle costs. This webinar will present the main properties of the new copper alloy conductors and how they allow to respond to the transmission and distribution network new challenges. Also a concrete case study for a 70 km line will be presented, stressing the relevance of the cost of losses and minimizing the total cost of ownership.

This document discusses the characteristics and performance of power transmission lines. It covers the following key points:
- The design and operation of transmission lines considers voltage drop, line losses, and transmission efficiency, which depend on the line constants R, L, and C.

Surge impedance sil
Power flow through overhead transmission lines is limited by concerns over electrical phase shift, voltage drop, and thermal effects. Specifically:
- Surge impedance loading limits power flow to prevent excessive phase shift, which can cause instability. This limit depends on system voltage and transmission line characteristics.
- Voltage drop limits power flow to maintain voltage levels within 5-10% of the sending voltage. This usually limits lines 50-150 miles long.
- Thermal limits prevent overheating of conductors and maintain structural integrity. This usually determines the limit for lines under 50 miles. Longer lines are limited by phase shift or voltage drop first.

Power upgrading of transmission line by combining ac dc transmission
Long extra high voltage (EHV) ac lines cannot be loaded to their Thermal limits in order
to keep sufficient margin against transient instability. With The scheme proposed in this
project, it is possible to load these lines very close to their thermal limits. The conductors
are allowed to carry usual ac along with dc superimposed on it.
The added dc power flow does not cause any transient instability. This Paper gives the
feasibility of converting a double circuit ac line into composite ac– dc power transmission
line to get the advantages of parallel ac–dc transmission to improve stability and damping
out oscillations. Simulation and experimental studies are carried out for the coordinated
control as well as independent control of ac and dc power transmissions. No alterations of
conductors, insulator strings, and towers of the original line are needed. Substantial gain in
the load ability of the line is obtained. Master current controller senses ac current and
regulates the dc current orders for converters online such that conductor current never
exceeds its thermal limit.
Problems in overhead transmission line

Symptoms of problems can be identified through techniques like measuring transmission line corona and gap discharges. Novel condition monitoring techniques are deployed to inspect lines and identify defective equipment online for maintenance.
Attenuation and surge impedance loading
- Attenuation refers to the loss of signal strength that occurs along transmission lines and is measured in decibels per kilometer. It is influenced by factors like line construction, frequency, weather conditions, and faults.
- The attenuation constant α determines the exponential decrease in amplitude per unit length of the line. The phase constant β determines the linear change in phase per unit length.
- Surge impedance is the characteristic impedance of a lossless line and is a measure of the maximum power that can be delivered by the line at unity power factor, known as surge impedance loading. It can be increased by raising voltages or decreasing the surge impedance through series and shunt capacitors.
Types of transmission lines
This document provides information about transmission lines presented by Shivam Patel. It begins with an introduction to transmission lines and defines them as electrical lines used to transmit electrical waves.

Cable sizing to withstand short-circuit current - Example
This document provides an example calculation of short circuit current for a power cable network. It first outlines the main design criteria for rating cable withstand for short circuit stresses. It then describes four methods for calculating short circuit current - ohmic, infinite bus, per unit and MVA methods. The example focuses on using the MVA method, providing equations and steps for calculating the equivalent short circuit power at different points in the network and converting this to a symmetrical fault current value. Resistances and reactances of cable sections are also included.
Lec transmission line
Transmission lines guide electrical energy from one point to another. They have two ends - an input end connected to the source, and an output end connected to the load. Common types of transmission lines include twisted pair, coaxial cable, and optical fiber. Twisted pair comes in unshielded and shielded variants, with shielded providing better protection against interference. Coaxial cable carries signals of higher frequencies than twisted pair. Optical fiber uses light pulses to transmit data over long distances at high speeds. Wireless transmission uses electromagnetic waves like radio waves, microwaves, and infrared to transmit data through the air without a physical medium.
Electrical transmission
This document discusses the mechanical design of overhead transmission lines. It covers the key components of overhead lines including conductors, supports, insulators, and cross-arms. For conductors, it describes common materials like copper, aluminum, and steel reinforced aluminum. For supports, it outlines wood, concrete, and steel poles. It also lists different types of insulators like pin, suspension, and strain insulators.

Analysis and design of three legged 400 kv double circuit steel transmission
This document summarizes the analysis and design of three-legged 400kV double circuit steel transmission line towers with angle and tube sections. The study models the towers in STAAD.Pro to analyze member forces and deflections under various loading conditions. It finds that the tube section tower design has better force-weight performance, with member forces and overall weight reduced by around 20% compared to the angle section tower. The tube section tower thus provides a more economical design for the three-legged 400kV transmission line towers.
Cable sizing to withstand short circuit current
In a cable a short circuit causes very extreme stresses which are proportional to the square of the current:
• A temperature rise in the conducting components subjected to current flow such as conductor, screen, metal sheath, armour. Indirectly the temperature of adjoining insulation and protective covers also increases,
• electro-magnetic forces between the current-carrying components.
The temperature rise is important for its effect on ageing, heat pressure characteristics etc., and should be limited to a permissible short-circuit temperature. The thermo-mechanical effects of the current shall also be considered.
For a given short-circuit duty therefore the short-circuit capacity of a cable installation is to be investigated with respect to all these parameters. For multi-core cables in most instances the thermal effect - related to the magnitude of fault current and clearance time - is the critical parameter, since the cable will normally have enough mechanical strength. With single-core cables however, in addition, the mechanical effect - related to the magnitude of the peak short-circuit current - is of such significance that, next to the thermal, the mechanical with- stand of both cable and its supports is to be investigated.
Also accessories must be rated with respect to thermal and mechanical short-circuit stresses.
The short-circuit withstand of a cable system is not quantitatively defined with regard to permissible number of repeated short circuits, degree of deformation or destruction or impairment quality. It is expected, however, that a cable installation will remain safe in operation and that any deformation remains within tolerable limits even after several short circuits.

Different transmission modes include TEM where electric and magnetic fields are orthogonal to the direction of propagation. The transmission line is modeled as a distributed circuit with inductance and capacitance. This leads to transmission line equations that can be solved as wave equations.

New generation of copper alloy conductors for overhead electricity lines
This document summarizes the key advantages of micro-alloyed copper conductors for overhead power lines compared to traditional aluminium conductors. Micro-alloyed copper conductors have higher energy efficiency due to lower electrical resistance and losses. They allow for higher operating temperatures and temporary overloads which provides more flexibility for grid operators. Life cycle cost analyses found the total cost of new lines and upgrades of existing lines to be similar or lower for copper conductors despite their higher initial cost, due to lower energy losses over the line lifetime.

Overhead line conductors are traditionally a domain for aluminium, using either steel reinforced aluminium or aluminium alloys. Using copper for overhead lines might surprise some people because it is a substantially heavier material. Weight, however, is not the most crucial characteristic of the conductor. Its smaller section and hydrophobic coating reduces the wind and ice loads on the conductors, which makes the overhead line more resistant and resilient to weather conditions.
Also, the higher conductivity of copper reduces the losses and the life cycle cost of the overhead line.

New technological advancements have made copper die-casting commercially viable for producing copper rotors. This allows copper rotors to be mass produced. Copper rotors provide benefits like higher efficiency, extended motor life, and potential for smaller motor size compared to aluminum rotors. Recycling copper rotors is both economically and environmentally feasible due to the high copper content. These innovations are stimulating market growth for copper rotor technology.
Micro-alloyed copper overhead line conductors - PowerGrid International Augus...
This document discusses microalloyed copper overhead line conductors (CAC) as an alternative to traditional aluminum conductors. CAC has a smaller cross-section but higher conductivity than aluminum, allowing it to carry the same current load while reducing energy losses. Though CAC is more expensive initially, the lifetime costs are lower due to much higher maximum operating temperatures and reduced losses over the conductor's lifespan. CAC is particularly suitable for connecting remote renewable energy generation to the grid due to its ability to handle short-term overloads without damage.
Copper alloy conductors for overhead lines - CIGRÉ Regional South-East Europe...
Transmission network operators are facing substantial and often contradictory challenges. A highly variable renewable energy supply and an increased focus on energy efficiency require the reinforcement of the grid. However, resistance to the construction of new lines is huge. Micro-alloyed copper conductors can be part of the solution. Their energy efficiency and their ability to cope with temporary capacity overloads are highly valued features. Such overloads are possible due to the higher resistance of copper against creep at high temperatures. The energy efficiency of the copper conductor compensates for its higher initial cost. As a result, its life cycle cost (LCC) is often lower than that of a steel reinforced aluminium (ACSR) conductor. This was the finding of two feasibility studies conducted by DNV GL (KEMA). The first study examined the construction of new lines; the second investigated the refurbishment of existing lines. The latter study also demonstrated why the higher specific weight of copper compared to an ACSR conductor does not require any reinforcement of the overhead line towers. The smaller cross section combined with a hydrophobic coating results in a much lower wind and ice load, which is a decisive factor for determining the required strength of the towers. This makes the copper conductor particularly suitable in cold and windy climates.

Characteristics of overhead conductors
Characteristics of overhead conductors, the sizes of overhead conductors and the advantages along with fault finding methods are discussed int his presentation.
Conductors
1. Conductors are materials that allow the flow of electric charges through them. Most metals are good conductors due to their crystalline structure and delocalized electrons.
2. In metallic solids, the atomic orbitals overlap to form energy bands. In conductors, the valence band is partially filled or overlaps with the empty conduction band, allowing electrons to move freely through the material.
3. Common good conductors include copper, silver, and gold. Conductivity decreases with increasing temperature as atomic vibrations interfere with electron flow.
4. Some materials become superconductors below a critical temperature, allowing infinite conductivity and perfect diamagnetism due to the Meissner effect. This occurs due to
Electrical conductors & insulators

The document discusses different types of overhead conductors used in transmission and distribution lines including stranded conductors, AAC, AAAC, ACSR, ACAR, smooth body ACSR, expanded ACSR, and ACCC. It provides details on their construction, materials used, properties and applications. Stranded conductors have increased flexibility and mechanical strength. AAC uses aluminum and is used where corrosion resistance is important. AAAC and ACAR use aluminum alloys for improved strength and properties over AAC. ACSR combines aluminum and steel. ACCC uses a lightweight carbon-fiber composite core.
Hard-Drawn Copper Conductors for Over Head Power Transmission
1. This document establishes standards and requirements for hard-drawn copper conductors used for overhead power transmission. It specifies dimensions, weights, resistances, and mechanical and electrical properties.
2. Standards include tables that specify the diameter, weight, and resistance for solid and stranded copper conductors. Tolerances on diameter and resistance are also provided.
3. The document describes test methods for mechanical properties like tensile strength and elongation, as well as electrical resistance tests to ensure conductors meet the specifications. It also outlines sampling procedures and criteria for acceptance or rejection of test results.
AST 406 Conductors
The document discusses conductors, semiconductors, and insulators. It defines conductors as substances that allow free flow of electrical charges, like metal wires and graphite rods. Semiconductors have conductivity between conductors and insulators, allowing some control of charge flow. Insulators do not allow charge flow and include materials like plastic, wood, and glass. The document discusses factors that affect conductance, including length, diameter, temperature, and material of a wire. Copper is identified as the best conducting material.
Conductor types and sizes
The document discusses different types of conductors used in power transmission. It describes the major materials used which include copper, aluminum, and aluminum alloys. The major types of conductors are identified as AAC (All Aluminum Conductor), AAAC (All Aluminum Alloy Conductor), ACSR (Aluminum Conductor Steel Reinforced), and ACAR (Aluminum Conductor Aluminum Alloy Reinforced). Key factors to consider in conductor selection include physical properties of the materials, mechanical characteristics, electrical performance, and cost. The design of conductors involves tradeoffs between these various factors.
Conductors and Insulators-quiz
Conductors allow electric current to flow through them, with examples including aluminum, silver, copper, gold, and iron. Silver is the best conductor, while copper is commonly used for wires due to its availability and low cost. Insulators do not allow electric current to pass through, protecting people from harm, with examples being glass, rubber, plastic, clay, wood, and paper. Glass is the best insulator of electricity, followed by plastic. The document provides information on conductors and insulators of electricity through definitions, examples, and a short quiz.
Lecture 09 transmission lines
This document provides an overview of transmission lines. It discusses how transmission lines transport electric power from generators to loads over long distances using high voltages. The power is then stepped down at distribution substations before being delivered to customers. Transmission lines can be overhead lines suspended from poles or towers, or buried underground cables. They have series resistance, inductance, and shunt capacitance per unit length that determine their power capacity.
Bundle conductors in transmission line
Bundled Conductors are used in transmission lines where the voltage exceeds 230 kV.
At such high voltages, ordinary conductors will result in excessive corona and noise which may affect communication lines.
The increased corona will result in significant power loss. Bundle conductors consist of three or four conductors for each phase.
The conductors are separated from each other by means of spacers at regular intervals. Thus, they do not touch each other.

Cathodic prevention of steel rebars in concrete the international outlook
The fundamental application of " cathodic prevention " of steel reinforcement in concrete was ideated and developed by Professor Pietro Pedeferri. It was successfully applied since 1989 in Italy on Viaduct St. Nicholas I of the highway Rome - Aquila - Teramo and in 1996 in the western underbroadwalk of the Sydney Opera House. Over the past 20 years it has spread throughout the world and particularly in Northern Europe, Middle East and Australia being recognized as the most reliable technique to combat corrosion for new buildings and infrastructure where reinforced concrete is exposed to possible contamination from chlorides. This memory is a review of some of the most significant industrial cases reported in the international literature.
Durrat Al Bahrain and the NAKILAT shipyard in Qatar are two recent projects developed in the Middle East. Cathodic Prevention of West Swanson Dock in Melbourne was the largest project completed in Australia in the last decade.
Other significant experiences in China and North Africa are a sign of the vitality of this technique in the developing countries.

Bus duct fabrication
Bus ducts are used to carry high currents between generators and transformers in power stations. They use thick aluminum conductors that are enclosed in aluminum to safely carry large currents up to 20,000 amps. Aluminum is used as the conducting material due to its lower cost compared to copper. There are two main types of bus ducts: isolated phase and segregated phase. Isolated phase ducts have each phase conductor enclosed separately while segregated phase ducts house the three phases together with insulating barriers between them.

Energy efficiency, structural change and energy savings in the manufacturing ...
- Structural changes in manufacturing have significantly reduced energy consumption in Denmark since 1990 through growth in lower intensity sectors like food production.
- Energy efficiency improvements also contributed, especially from 2010-2014, lowering consumption alongside structural changes.
- A decomposition analysis found that decreases in consumption from 2006-2014 were mainly from structural effects in the first half, and efficiency gains in the latter half.
- Reported energy savings from Denmark's energy efficiency obligation scheme align with estimated efficiency improvements, though some autonomous gains likely occurred too.
Energy Sufficiency Indicators and Policies (Lea Gynther, Motiva)
This policy brief looks at questions ‘how to measure energy sufficiency’, ‘which policies and measures can be used to address energy sufficiency’ and ‘how they are used in Europe today’.
Energy sufficiency refers to a situation where everyone has access to the energy services they need, whilst the impacts of the energy system do not exceed environmental limits. The level of ambition needed to address energy sufficiency is higher than in the case of energy efficiency.
This is the 13th edition of the Odyssee-Mure on Energy Efficiency Academy, and number 519 in the Leonardo ENERGY series. The recording of the live presentation can be found on https://www.youtube.com/watch?v=jEAdYbI0wDI&list=PLUFRNkTrB5O_V155aGXfZ4b3R0fvT7sKz

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
