why C.T secondary are rated 5A generally?
Answer Posted / rahul
more of our meter & relay are of 1A to 5A range to operate
because the accuracy,loss & stability factor so alwayes the
CT O/P is 1A to 5A

HOW TO SELECT THE COPPER CABLE SIZES OF MOTORS,TRANSFORMERS?
a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
