Design a circuit using JK flip-flops that takes in a binary stream B0B1B2B3 and outputs 1 at a time t if the stream recieved thusfar (i.e. BoB1..Bt-1Bt), when read as an unsigned binary number, is divisible by 3.
A three-phase substation transformer operating at 34.5kV is loaded to 24 MVA. What is the per-phase current? (assume balanced conditions)
The main mission of this project is to design and build a tap changer which is going to be fitted to power transformers for regulation of the output voltage to required levels for the Micro Grid. The tap changer system will consist of 9 changers with..
Saw on internet some equations to convert from frequency in hertz to mph. Some equations need a gear ratio while others do not. I found the equation mph = circumference * RPM * 60.
