SUMMARY
The discussion focuses on using a current sense transformer to induce voltage from a 20kVDC pulse for energizing an LED in synchronization with the pulses. The correct method involves passing one lead of the power cable through a ferrite toroidal core, creating a single turn coil, while winding a secondary coil around the toroid to generate sufficient voltage. This technique allows for minimal power extraction from the lead, ensuring safe operation while lighting the LED. Reference materials include "Instrument Transformers" and Current Transformers for further understanding.
