What is circuit km?
A 1 km length of double circuit is reported as 2 km of circuit. A three-phase circuit may have “single-phase” (or “two-phase”) branch line taps. This terminology derives from the fact that only one (or two) of the phases of the three-phase circuit – plus (in most areas) a neutral conductor – are involved.
What is CKM in transmission line?
Subscribe Now. NEW DELHI: To meet the government’s target of providing 24×7 power to all, NITI Aayog has set a target of adding 51,400 circuit km (CKM) transmission line this fiscal, 82 per cent more than what was achieved in 2015-16.
What is double circuit line?
Double circuit transmission line refers to the arrangement in which a total of six conductors are provided to make two different transmission circuit. In double circuit transmission line, there are two circuits each consisting of three conductors corresponding to three phases.
What are the types of transmission lines?
Types of transmission line include parallel line (ladder line, twisted pair), coaxial cable, and planar transmission lines such as stripline and microstrip. The higher the frequency of electromagnetic waves moving through a given cable or medium, the shorter the wavelength of the waves.
What is single circuit line?
Single Circuit Transmission Line refers to an arrangement of conductor over the Transmission Tower. In Single Circuit Transmission Line, three conductors corresponding to three distinct phases i.e. R, Y & B phase are run on the Transmission Tower.
What is the simple circuit?
A simple circuit is one in which there is a single voltage source and a single resistance. One statement of Ohm’s law gives the relationship between current I, voltage V, and resistance R in a simple circuit to be I=VR I = V R .
What is a live circuit?
Working near energized circuits. Working on live circuits means actually touching energized parts. Working near live circuits means working close enough to energized parts to put you at risk even though you may be working on de-energized parts.
How is circuit length measured?
The overall length of wiring in a circuit is calculated and displayed as the value for Length in the Properties palette. The Length is calculated as the sum of the distances along the X, Y, and Z axes. In the following example, the length is calculated as 12′ 11 7/64.”
How do you find the length of a circuit?
To obtain the length of a ring circuit you will need to measure the end-to-end resistance of the conductors, this is the same test normally performed to confirm ring continuity. The figures obtained are divided by the resistance per meter for the CSA of cable, giving the approx length.
