To calculate the maximum power delivered through a 400 kV transmission line, we use the formula ( P = V \times I ), where ( P ) is power, ( V ) is voltage, and ( I ) is current. The maximum current that can be carried by the 2x520 sqmm conductors depends on their thermal limits, which can vary based on ambient temperature and installation conditions. Assuming a maximum current of around 800 A for this conductor type, the maximum power can be estimated as ( P = 400,000 , V \times 800 , A = 320,000,000 , W ) or 320 MW. However, this is a simplified calculation and actual power delivery would depend on various factors, including losses and line characteristics.

What does ohbr stand for when referring to reyrolle 275 and 400Kv circuit breakers?
In the context of Reyrolle 275 and 400kV circuit breakers, "OHBR" stands for "Overhead Bridge Restraint." This refers to a mechanism designed to secure the circuit breaker in place and prevent excessive movement during operation or in the event of a fault. The OHBR system helps to maintain the structural integrity and stability of the circuit breaker under various operating conditions.

Why leakage reactance is kept small?
Leakage reactance is useful for limiting the short circuit current in transformer and generators. therefore normally the reactance of transformer varies for 4.5% for distribution transformer to 12.5% for 400KV class.
What is a power transformer?
A transformer is a static machine utilized for changing force starting with one circuit then onto the next without evolving recurrence. This is an exceptionally fundamental meaning of transformer. The historical backdrop of transformer was started in the year 1880. In the year 1950, 400KV electrical force transformer was presented in high voltage electrical force framework. In the mid 1970s, unit rating as expansive as 1100MVA was delivered and 800KV and considerably higher KV class transformers were produced in year of 1980.
Why do you step up voltage from 11kV to 400kV during transmission?
Stepping up voltage from 11kV to 400kV during transmission is primarily done to reduce energy losses over long distances. Higher voltages allow for lower current flow for the same power transfer, which minimizes resistive losses (I²R losses) in the transmission lines. Additionally, higher voltage transmission is more efficient and enables the use of thinner, lighter conductors, reducing infrastructure costs. This process is typically achieved using transformers at substations.
