Find Induced Voltage in Inductor
Given a Bushing Current Transformer (BCT) with a shorted secondary terminal. The BCT has 300 milliHenry (mH) rating and it has 0 to 3.5 A or 3500 mA current flowing through it. Assuming an apprentice electrician accidentally remove the shorting wire on the BCT secondary terminal while the circuit was energized at that instant the current is flowing at 2 microsecond and at its maximum value of 3500 mA.
Calculate the induce voltage that the apprentice electrician will be exposed?
Important to remember: Do not remove the shorting wire on any ENERGIZED CT or BCT secondary terminal block because of very High Induced Voltage that can generate an ARC Flash Hazard.
The answer is valid if the units of measurement are in mH, mA, and microsecond. So you need to make measurement conversion to satisfy the calculator algorithm.
