Distinguishing Aspects of Ultra High Voltage in Construction
Specific Characteristics of Ultra High Voltage
Ultra high voltage (UHV) is a term integral to the power transmission field. Apart from the grandiose figure of being able to carry more than 800 kV, UHV brings along a set of specific characteristics, distinguishing it from usual voltage levels.
Higher Power Density
UHV transmission allows for a higher power density, meaning it can transfer larger amounts of power through a single transmission line. This feature reduces the need for parallel or multiple transmission lines, therefore saving costs and real estate.
Extended Transmission Distance
One of the crucial elements of UHV is its ability to transmit electricity over longer distances without appreciable power losses. Due to its increased voltage level, UHV is less susceptible to resistance-related power losses, allowing energy to travel farther.
The Significance of Capacitive and Inductive Load in UHV
In any electrical system, capacitive and inductive loads play an important role, and UHV is no exception.
Inductive Load Impact
Inductive load refers to the consumption of reactive power. A high amount of inductive load can cause voltage instability in the system. However, UHV shows an extremely high power capability, making it less sensitive to large inductive loads.
Capacitive Load Impact
Capacitive load creates reactive power, and can lead to excessively high voltages in the system. UHV systems often require measures like shunt reactors to absorb the excessive reactive power and control the voltage level.
The Regulatory Framework for Ultra High Voltage
Given the potential impacts of UHV on the environment and surrounding community, its implementation and operation are governed by multiple regulations.
Authorities Regulating UHV
Several national and international authorities exert regulatory control over the use of UHV technology. For example, in the United States, the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC) play significant roles.
Key Regulations
Primary regulations that typically apply to UHV include rules on electromagnetic fields, power transmission, safety standards, noise levels, etc. These strict guidelines are intended to protect workers and the general public from any potential health or safety hazards.
