What is Relay Setting Calculations for 6 kV Bus about?
The document describes the calculation of relay settings for a substation protection scheme. It involves calculating the fault current, protective device settings, and operating times. The key steps are: 1) Calculating the fault current of 14kA at the 6kV bus based on the source impedance, cable impedance, and transformer impedance. 2) Determining the protection settings for outgoing feeders, incomers, bus section feeders, and other devices based on their pickup settings, CT ratios, and fault current.
