What is the meaning of key single line diagram?

Answer Posted / keshava narayana.g

KEY SINGLE LINE DIAGRAM is a skeleton drawing of the MSLD
(MAIN SINGLE LINE DIAGRAM) in which only equipment details
will be there rather than specification of the individual
equipment.
ex. If we take an Current Transformer details in MSLD
it will have No of Core,Current Ratio,Burden,Class etc.,
but were as in key single line diagram only Core deatils
will be there.
Actually the concept of key single line diagram is to show
the equipment details in perticular drawing rather than
there specification.
