Overhead T&D, Direct Current Technology
Direct current technology delivers efficient DC power distribution via rectifiers, converters, and power electronics, enabling microgrids, energy storage, HVDC links, photovoltaics, and electric vehicle charging with reduced losses and improved reliability.
Direct Current Technology Fundamentals
Direct current (DC) is the preferred technology for moving large amounts of power across long distances. DC results in higher overall efficiency and reliability than an equivalently sized alternating current (AC) system moving the same amount of power.
The Advantages of DC
More efficient: Over long distances, DC transmission can move more power with less electrical losses than an equivalent AC transmission line. For…

Electricity Transmission
Electricity transmission delivers high-voltage power from generating stations to substations across vast electrical grids. Using transmission lines, transformers, and substations, it ensures efficient energy transfer, grid stability, and reliable service to businesses and industries.
Electricity Transmission Fundamentals
History and Evolution of Transmission
Early electricity networks in the late 1800s used direct current (DC), championed by Thomas Edison. However, DC was inefficient for long-distance delivery. Nikola Tesla and George Westinghouse pioneered alternating current (AC), which allowed voltage to be stepped up and down using transformers. This advantage made AC the global standard.
Since then, transmission systems have expanded to…

Electrical Insulator Explained
Electrical insulator materials resist current flow to protect people and equipment. Used in power transmission and switchgear, electrical insulators rely on high resistivity, dielectric strength, and breakdown voltage to prevent leakage.
Electric power only works when it stays inside its intended path. An electrical insulator exists to make sure it does. Unlike conductors, which are chosen to carry current, it is chosen because it prevents current from passing.
In real systems, an electrical insulator separates energized components from grounded structures, confines electric fields within equipment, and prevents accidental discharge. When insulation fails, electricity does not quietly drift. It escapes violently,…

Costly Interconnection Delays
Costly interconnection delays stall grid connection for solar, wind, and storage, driven by interconnection queue backlogs, transmission constraints, lengthy permitting, and network upgrade studies, inflating project CAPEX, financing risk, and PPA timelines.
Costly Interconnection Delays and Their Impact on Workplace Safety
Policy debates on solar incentives and valuation make headlines across the nation, but less attention is paid to the nuts and bolts of solar installation: the interconnection process.But the struggle there is very real. Take Hawaii, where the high volume of solar applications and the slow interconnection process slowed distributed solar installations two years ago. Eventually, the process…

Power Line Carrier Communication Explained
Power line carrier communication enables data transmission over electrical power lines for grid automation, SCADA telemetry, and protective relaying, using coupling capacitors, line traps, and narrowband modulation to support substation monitoring and smart grid control.
Applications of Power Line Carrier Communication in Modern Power Systems
Power line carrier communication (PLCC) is a vital technology for electrical professionals to understand in today's evolving energy landscape. By utilizing existing power lines for data transmission, PLCC offers a cost-effective and reliable communication solution for a wide range of applications within industrial, commercial, and institutional power systems. In transmission engineering contexts, PLCC must…

Why Net-Zero is Cheaper for the UK
The United Kingdom has set an ambitious target to achieve net-zero greenhouse gas emissions by 2050. This goal necessitates a comprehensive transformation of various sectors, including energy, transportation, and agriculture. While the environmental imperatives are clear, there is growing evidence that this transition could also yield significant economic advantages for the nation.
Energy Sector Transformation
A pivotal component of the UK's net-zero strategy involves a substantial shift towards renewable energy sources. By 2040, projections suggest that wind and solar power will supply approximately 80% of the country's electricity needs. This transition is expected to reduce energy imports, enhancing national energy…

FERC Complaint Targets Duke, PJM Transmission Planning
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues that such local planning, lacking independent oversight, leads to inefficient and costly transmission development, resulting in unjust and unreasonable rates for consumers.
Background
Transmission planning involves determining the necessary infrastructure to transport electricity from generation sources to consumers. In the United States, this planning is typically conducted by transmission owners, which are often investor-owned utilities. These entities are responsible for…

How Dangerous is Linemen Work?
Many occupations pose risks to workers, but few match the dangers that linemen face daily. Linemen play a critical role in maintaining and restoring the power grid, often working in extreme weather conditions, at significant heights, and around high-voltage electrical systems. Their work is essential to modern life, yet it comes with life-threatening hazards.
Statistics highlight the dangers of lineman work. The fatality rate for lineworkers is nearly four times higher than the national average for all occupations. Each year, an average of 26 linemen lose their lives due to work-related injuries. Additionally, linemen experience a non-fatal injury rate of…
