Hi all, I come in peace, I need help with an exam question.
Q. A new circuit has been added to an existing three-phase installation forming part of a TT system protected by a 100mA RCD to BS61008. Explain how to accurately determine the external earth fault loop impedance Ze for this installation.
Any guidance would be greatly appreciated.
